INTRODUCTION
This job family standard (JFS) provides series definitions, titling instructions, and grading criteria
for nonsupervisory professional positions in the Mathematical Sciences Group, 1500, for General
Schedule (GS) and other “white collar” pay plans. In the General Schedule position classification
system established under chapter 51 of title 5, United States Code, the positions addressed here
would be two-grade interval positions.
This JFS is divided into three parts. Part I contains occupational information that is applicable to
Federal work covered by the JFS without regard to pay plan or classification system. Part II
provides the grading criteria for positions classified in accordance with GS grade definitions. Part
III includes explanatory material about the development of this JFS.
The term “General Schedule” or “GS” denotes the major position classification system and pay
structure for white collar work in the Federal government. Agencies no longer subject to chapter
51 have replaced the GS pay plan indicator with agency-unique pay plan indicators. For that
reason, reference to General Schedule or GS has been omitted from much of this JFS.
Coverage
This job family standard covers the following occupational series:

PART I – OCCUPATIONAL INFORMATION
Part I is intended for use by all agencies in evaluating professional positions in the Mathematics
Sciences Group, 1500. It provides series definitions, titling instructions, and detailed occupational
information for this job family.
General Series Determination Guidelines
For a variety of reasons, selection of the correct series for a position is an essential part of the entire
human resources management process. For example, qualification requirements used in recruiting
are based on the series of the position; career ladders are influenced by the series; and organizational
structure is often designed with consideration of the series of assigned positions.
Determining the correct series for a position is usually apparent by reviewing the assigned duties and
responsibilities and then comparing them to the series definitions and general occupational
information the job family standard (JFS) provides. Generally, the series determination for a
position is based on the primary work of the position, the highest level of work performed, and the
paramount knowledge required to do the work of the position. Normally, it is fairly easy to make
this decision. However, in other instances, determining the correct series may not be as obvious.
Use the following guidelines to determine the predominant series when the work of a position
matches more than one job family or occupational group. Also, when the work of a position falls
into more than one series within this job family, it may be difficult to determine which particular
series predominates. In such situations, apply the guidelines below in the order listed to determine
the correct series.
Paramount knowledge required. Although there may be several different kinds of work in the
position, most positions will have a paramount knowledge requirement. The paramount
knowledge is the most important type of subject matter knowledge or experience required to do
the work.
Reason for existence. The primary purpose of the position or management’s intent in
establishing the position is a positive indicator for determining the appropriate series.
Organizational mission and/or function. Positions generally align with the mission and
function of the organization to which they are assigned. The organization’s function is often
mirrored in the organizational title and may influence the appropriate series.
Recruitment source. Supervisors and managers can help by identifying the occupational series
that provides the best qualified applicants to do the work. This is closely related to the
paramount knowledge required.
Although the work of some positions may require applying professional mathematical or related
knowledge and skills, classification as professional positions in the Mathematics Sciences Group,
1500, may not be appropriate. The
Additional Occupational Considerations section of this JFS
provides examples where the work may involve applying related knowledge and skills, but not to the
extent that it warrants classification to this job family.
Additional information may be found in OPM’s publication
The Classifier’s Handbook.

Classifying Professional Scientific Work
Professional scientific work involves exercising discretion, analytical skill, judgment, personal accountability and
responsibility for creating, developing, integrating, applying, and sharing an organized body of knowledge that
characteristically is:
uniquely acquired through extensive education or training at a recognized college or university;
equivalent to the curriculum requirements for a bachelor's or higher degree with major study in or pertinent to
the specialized field; and
continuously studied to explore, extend, and use additional discoveries, interpretations, and applications to
improve data quality, materials, equipment, applications, and methods.
Interdisciplinary Professional Positions
An interdisciplinary position is a position involving duties and responsibilities closely related to more than one
professional occupation. As a result, you could classify the position into two or more professional occupational
series. The nature of the work is such that persons with education and experience in two or more professions may
be considered equally well qualified to do the work. In both categories the position description should show clearly
that the position is interdisciplinary and indicate the various series in which the position could be classified. The
final classification of the position is determined by the qualifications of the person selected to fill it.
For further guidance on the use and classification of interdisciplinary positions, refer to
The Classifier’s
Handbook.

Distinguishing Between Professional and Technical Work
It is important to determine whether a position is comprised of technical or professional work. It is not always easy
to differentiate between the two because some tasks are common to both. The developmental work of professional
positions and the demanding work of high level technical positions are sometimes similar. Typical distinctions
between technician and professional work follow.
Professional Work Involves:
Technical Work Involves:
Applying a range and depth of knowledge
acquired specifically through intensive learning
of the phenomena, theories, and concepts of a
scientific body of knowledge.
Creating, exploring, evaluating, and sharing
solutions for scientific, mathematical, and/or
statistical problems, methods, conditions, and
issues.
Understanding theories, concepts, principles,
and their relationships underlying the practice of
a professional scientific discipline to achieve

work performed and/or to protect the public’s
interests in the quality of life, health,
infrastructures, and natural resources.
Identifying, analyzing, advising, consulting, and
reporting on scientific, theoretical, and factual
data, conditions, and problems.
Independently assessing, resolving, and
predicting the relationships and interactions of
data and findings under varying conditions.

Official Titling Provisions
Title 5, United States Code, requires OPM to establish the authorized official position title that includes a basic title (e.g.,
Mathematical Statistician) that may be appended with one or more prefixes and/or suffixes. Agencies must use the
official position titles for human resources management, budget, and fiscal purposes. Instructions for assigning official
position titles are provided for specific series in this section.
Supervisors and Leaders
Add the prefix “Supervisory” to the basic title when the agency classifies the position as supervisory. If the position
is covered by the General Schedule refer to the
General Schedule Supervisory Guide for additional titling and
grading information.
Add the prefix “Lead” to the basic title when the agency classifies the position as leader. If the position is covered
by the General Schedule refer to the
General Schedule Leader Grade Evaluation Guide for additional titling and
grading information.
Research Positions
Add the prefix “Research” to the basic title when the work satisfies the criteria for research as defined in the
Research Grade Evaluation Guide.
Specialty or Parenthetical Titles
Specialty titles are typically displayed in parentheses and referred to as parenthetical titles. OPM has not prescribed
parenthetical titles for five of the series in this JFS:
General Mathematics and Statistics, 1501;
Actuarial Science, 1510;
Operations Research, 1515;
Mathematics, 1520; and
Mathematical Statistics, 1529.
For these five series agencies may supplement the basic position titles with agency established specialty titles if necessary
for recruitment or other human resources needs. However, for the Statistics series, 1530, this standard prescribes the use
of the following specialty titles:
Agriculture Engineering
Biology Health
Demography Medicine
Economics Operations and Administration
Education Social Science
Agencies may use only the above listed specialty titles to supplement the basic titles for the Statistics series, 1530.
Organizational Titles
Organizational and functional titles do not replace, but complement official position titles. Agencies may establish
organizational and functional titles for internal administration, public convenience, program management, or similar
purposes. Examples of organizational titles are Branch Chief and Division Chief. Examples of functional titles are Chief
of Operations and Chief of Policy Development.

Functional Classification Codes
Functional Classification for Professional Work. The National Science Foundation (NSF) manages a system of
functional classification codes to describe the work done by scientists and engineers. NSF uses these data to
conduct studies of the science and engineering workforce. To meet the needs of the NSF, OPM requires agencies to
document and maintain functional classification codes for positions in science and engineering occupations.
The
Guide to Personnel Data Standards provides a list of the applicable occupations and definitions of the functional
classification codes. Use established internal agency procedures to assign the appropriate code for positions
covered by series in this JFS. A complete list of valid functional classification codes is given below.

ACTUARIAL SCIENCE, 1510
Qualification Standards
Series Definition
This series covers positions that manage, supervise, lead, or perform scientific work in the field of actuarial
science. Actuarial science involves professional knowledge of the disciplines of mathematics, statistics,
business, finance, economics, and insurance. The work requires applying this knowledge to programs or
problems related to the financial risks posed by life, health, retirement/pension, and property/casualty entities
and contingencies.
This series requires a
functional classification code.
Titling
The basic title for this occupation is Actuary.
Occupational Information
General Occupational Information
Actuaries in the Federal Government evaluate the financial status of Federal programs designed to help protect
individuals, businesses, and pension plans against adverse financial contingencies. They also play an active
role in designing, modifying, and administering these Government programs and in providing the facts and
estimates that serve as the foundation for management decisions and actions in administering these programs.
These programs include:
Old Age, Survivors, and Disability Insurance (commonly known as Social Security);
Supplemental Security Income (cash assistance for low income, aged, blind, and disabled persons);
Medicare (hospital insurance and supplementary medical insurance for the aged and disabled);
Medicaid (health care for low income persons);
Unemployment Insurance;
Pension Benefit Guarantee Insurance;
private pensions and other employee benefit plans;
property insurance programs such as crop, hail, and flood insurance;
life and health insurance, retirement and disability pensions, and other benefits for Federal military
and civilian employees;
insurance plans protecting mortgages, loans, savings, and investments;
estate, gift, and other tax regulations applicable to trusts, pension funds, insurance programs, gifts,
etc.; and
pension and unemployment benefits for retired employees.
Many Federal programs involve Federal trust funds that have specific financing sources that must be adequate
to cover promised benefits and other expenditures.
Actuarial Functions
Actuaries deal with the financial, economic, and social aspects of a rapidly changing world. Today there are
frequent discoveries in science and medicine, and growing complexities in business and finance. Actuaries
ensure the financial viability of programs designed to protect individuals, groups, and businesses against the
uncertain risk of future financial loss. They evaluate their past projections against actual experience to
determine the economic and social forces at work. Actuaries apply these findings to create future projections.
Because most programs involve a large amount of data, actuaries often study samples. They ensure that their
study samples accurately reflect the population studied and that they are using the most suitable statistical tools
to solve a problem.

ACTUARIAL SCIENCE, 1510 (continued)
Occupational Information (continued)
Major Actuarial Services
Actuaries provide the following nine principal services:
Cost Estimation – involves projecting future program cost estimates to form the basis for estimating
staffing needs and service capabilities.
Financial Status Evaluation – requires the actuary to compare estimated future program revenues and
expenditures, often over long periods, to assess trust fund adequacy. Federal law frequently requires
formal public reports on program financial status.
Insurance Valuation – involves calculating and compiling:
mortality, morbidity, and disability tables;
retirement, withdrawal, and remarriage rates;
joint and survivorship values;
annuity and insurance values; and
reserve and trust fund values.
These valuations are used to determine the stability of programs, the value of assets and liabilities, and
compliance with legal requirements.
Financial Projection – involves estimating future expenditure levels for benefits, administration, and
other Federal program costs. In many cases, the actuaries also estimate future program revenues. The
projections involve the following activities:
estimating future program participants such as insured persons, beneficiaries, and taxpayers;
calculating growth rates for various economic and programmatic factors such as the consumer
product index, wages, health care prices, and utilization; and
projecting incidence of certain risks such as death, disability, hospital admission, and pension plan
termination.
Some of these projections are used in documents such as the Annual Budget, Social Security and
Medicare Board of Trustees reports, and the Consolidated Financial Statement of the U.S. Government.
Legislative Proposal Evaluation – involves estimating or projecting the cost, impact, and actuarial
soundness of proposed legislation. The actuaries must prepare their study findings and supporting
evidence in nontechnical language for presentation to lay persons. To ensure proper interpretation and
implementation of their recommendations, some actuaries work closely with attorneys and other personnel
who are drafting proposed legislative and regulatory changes.
Calculating Program Cost – involves determining pay and salary premiums, wage thresholds, health
service payment updates, cost of living benefit increases, beneficiary coinsurance levels, and a host of
other statutory factors.
Consultation – involves advising policy makers on how to create effective and reliable programs for
addressing financial security. Some Government actuaries frequently work closely with members of
Congress and their staffs, key administration officials, national advisory commissions, and others. They
promote these relationships to ensure that their proposals will function as intended and that the financial
and operational implications are carefully considered.

ACTUARIAL SCIENCE, 1510 (continued)
Occupational Information (continued)
Improving Public Understanding – involves making presentations and participating in public forums to
explain financial status, costs, technical operations, and other program characteristics. Actuaries
frequently take a leading role in improving public understanding of complex programs.
Publishing Professional Findings – involves presenting research, study, and analytical findings at
professional conferences and in professional journals for critical review by qualified professionals.
Critiques in these forums play a necessary and invaluable role in advancing both the profession and
individual actuaries. Actuaries may perform many functions that require an actuarial background, but do
not require writing an equation, proving a theorem, or performing any activity that involves applied
mathematics. Their unique contribution is to communicate to their readers the mathematical
considerations that underlie their and others’ research, analysis, and study findings.
Actuaries typically specialize in one or more of the following categories of actuarial work:
Retirement Benefits including employer-sponsored defined benefit and defined contribution pension
plans, social security, and other cash retirement income sources.
Health Insurance – including individual policies (e.g., “Medigap”), employer-sponsored plans,
Government programs, and delivery systems such as health maintenance organizations, preferred provider
organizations, and fee-for-service indemnity plans.
Other Group Insurance – including protection offered through employers, unions, trade and professional
associations, and other organizations against the financial risks posed by such factors as death, disability,
workplace accidents or illnesses, and legal fees.
Other Individual Insurance – including life insurance, annuities, disability insurance, and reinsuring
other insurance products for high claim amounts.
Finance – including corporate finance, financial intermediation, capital management, and financial risk
management.
Investments – including pension and other accumulated reserve funds, asset management, and
asset/liability matching.
Property and Casualty Insurance – including business insurance, malpractice and other professional
liability insurance, worker’s compensation, homeowner’s insurance, and automobile insurance.

OPERATIONS RESEARCH, 1515
Qualification Standards
Series Definition
This series covers positions that manage, supervise, lead, or perform scientific work that involves designing,
developing, and adapting mathematical, statistical, econometric, and other scientific methods and techniques.
The work also involves analyzing management problems and providing advice and insight about the probable
effects of alternative solutions to these problems. The primary requirement of the work is competence in the
rigorous methods of scientific inquiry and analysis.
This series requires a
functional classification code.
Titling
The basic title for this occupation is Operations Research Analyst.
Occupational Information
General Occupational Information
Operations research is:
an advisory function that utilizes a structured approach to problem solving;
a rigorous process of scientific inquiry and analysis applicable to unique or recurring problems that
confront decision makers; and
the systematic examination and development of alternative courses of action to define and clarify the
advantages and disadvantages of available choices.
The primary purpose of operations research analysis is to provide decision makers with sound, scientific, and
quantitative information as a basis for making decisions. These decisions are often made under the following
types of conditions:
uncertainty arising from a lack of current experience and knowledge;
conflicts in objectives;
a variety of possible alternative; and/or
the failure of current systems to meet goals.
Types of Operations Research Work
Operations research analysts perform the following two broad types of work:
Methods Development and Assessment – involves applying expert knowledge of particular classes of
problems and the ability to develop associated problem solving methods. Analysts may specialize in one
or more areas including queuing theory, optimization methods, simulation, or artificial intelligence. They
advise other operations research analysts, scientists, or engineers on techniques best suited for analyzing
their problems.
Problem Solving – involves the ability to work directly to correct deficiencies or improve the performance
of systems, processes, or operations. Analysts doing this type of work are expert in methods of problem
solving and also have an in-depth knowledge of recurring or persistent subject matter problems.
Multidisciplinary Approaches
A key requirement of operations research analysis is the ability to work across disciplinary boundaries and to
develop multidisciplinary solutions to complex problems. For example, evaluating the capability of a high
performance fighter/bomber to reach and destroy its target may involve issues relating to:
aeronautical, electrical, electronic, and mechanical engineering;
physics;
mathematics; and
economics.

OPERATIONS RESEARCH, 1515 (continued)
Occupational Information (continued)
Analysts usually deal with a variety of broad issues, subject matter areas, and problems. Each assignment
presents a different question. Over time, analysts may gain considerable knowledge of some specialty fields,
yet operations research knowledge remains paramount. Analysts often borrow and adapt analytical methods
and modify techniques from other scientific, technical, and analytical disciplines. Similarly, professionals in
other fields may use the operations research approach to solve problems in their disciplines.
The Operations Research Analysis Process
The framework for the operations research analysis process is best understood in terms of concepts and phases.
Concepts
Three key conceptssystems, relationships, and modelsare important in understanding the analytical process
involved in problem solving. Each concept is described below:
A system is a group of interrelated, interacting, or interdependent elements forming a complex whole. A
process or operation may be a system. In this job family standard, the term system refers to the process and
operation of analysis.
A relationship is a statement about the similarities, differences, or interactions of two or more quantities or
measurements called variables. For example, a tall person probably weighs more than a short person. The
two measurements of height and weight are relative variables. There are other variables that relate to
weight, such as the person’s bone structure and body type. A person’s height and any of the other
variables may establish a relationship. Much of the work of operations research lies in identifying the
proper variables and their true relationships for use in solving a particular problem or evaluating
alternatives.
A model is a representation of the relationships that define a system or situation under study. It may be a
set of mathematical equations, a computer program, a hand-played game, a written scenario, an
experiment, or other type of representation ranging from verbal statements to physical objects. Models
permit the manipulation of variables to determine how a process, object, or concept would behave in
different situations, without using the time, risk, or expense of actual real world implementation.
Phases
The analytical process has four phases: problem definition, model development, hypothesis testing and
investigation, and predictions/explanations. Each phase is described below.
Problem Definition – usually takes the form of “what if” questions. In formulating problem statements,
analysts examine the objectives and criteria of systems to make sure they are studying the right problems.
They determine the context of problems to identify the:
principal decisions made;
relevant variables and true relationships;
alternative choices;
measures of effectiveness or success that distinguish among the alternatives; and
constraints.

Operations Research, 1515 (continued)
Occupational Information (continued)
Model Development – represents the important factors of the problem and their relationships to selected
features of the real world. Models permit experimentation and extend the evaluation of system
performance and reliability beyond the scope of practical testing. Analyses done with models may be the
only means to forecast performance for certain kinds of systems, for example, the world economy or
combat.
Using models leads to discovering cause and effect relationships that may otherwise go undetected.
Analysts develop or select models with which they can experiment to develop and explore choices or
hypotheses. They determine if the models describe the systems under study and test their reality by
measuring their sensitivity to various values of appropriate variables. After showing that a model is a fair
representation of reality, or that its limitations are acceptable for the current study, the model can be useful
for analyses.
Mathematical models cannot solve some problems. These problems usually include intangible
characteristics that quantitative terms cannot express. Foremost among such characteristics is the presence
of the human element.
Hypothesis Testing and Investigation – is repeated throughout the analytical process. The process
involves successive integration of analogies, patterns, and relationships, and usually involves feedback and
further restructuring. For new types of problems, analyses constitute a continuous cycle of formulating
problems, selecting the objectives, designing better alternatives, collecting data, building new models,
weighing costs against performance, questioning assumptions and data, reexamining objectives, and
identifying new alternatives.
Predictions/Explanations – are the end result of analyses. Analysts predict future events or explain past
events. They recommend the best alternatives, if they are found, and present relevant tradeoffs and
limitations so decision makers can make informed choices or take appropriate action.

Pure or Abstract Mathematics – is sometimes referred to as basic research. Relatively few
mathematicians perform basic research. This work involves studying and developing principles for their
own sake and possible future rather than immediate usefulness. Pure or abstract mathematics applies to
areas of mathematics such as:
differential geometry;
topology;
combinatorics;
discrete equations;
network theory; and
graph theory.
Applied Mathematics – concerns mathematical aspects of the physical, natural, and social sciences. In a
restricted sense, the term refers to using mathematical principles as tools in the fields of physics, chemistry,
engineering, biology, and the social sciences. Many mathematicians perform work in applied mathematics.
Typical areas of applied mathematics are:
linear and nonlinear ordinary and partial differential equations;
numerical analysis;
finite element and finite differences methods;
integral equations;
inverse scattering;
neural nets;
computational geometry;
visualization;
virtual reality;
robotics;
solid and fluid modeling;
linear and nonlinear control; and
nonlinear dynamics.

The basic title for this occupation is Mathematical Statistician.
Occupational Information
General Occupational Information
Mathematical statisticians perform duties in which the “problem” is the basic work unit. The size and
complexity of the problem varies extensively. Solving a problem usually requires that the mathematical
statistician use standard research procedures. These procedures, sometimes referred to as the scientific method,
include the following seven basic work processes:
defining problems;
conducting background research;
planning;
conducting investigations;
reducing findings to facts;
interpreting findings; and
documenting findings.
The science of mathematical statistics is a body of theories and methods for obtaining knowledge.
Mathematical statisticians do not merely rely on a collection of facts; instead they are characterized by the
techniques that they develop to design models for collecting quantified data. Mathematical statisticians design
and use methods that provide the technical framework for such activities as:
developing sampling strategies to collect data;
discovering the meaning of facts;
performing methodological research;
analyzing data and generating inferences about the real world based on analysis;
ensuring the accuracy of measurements that data represent;
evaluating the precision and validity of estimates;
investigating sources and magnitude of error in data;
planning and executing sample or census surveys;
designing and conducting experiments;
analyzing experimental design;
performing operations research; and
instituting procedures for quality control in production.

MATHEMATICAL STATISTICS, 1529 (continued)
Occupational Information (continued)
Mathematical statisticians apply or are guided by concepts, theories, methods, and techniques such as:
probability;
statistical estimation;
data analysis;
linear model analysis;
time series analysis;
survey design;
questionnaire design;
statistical quality control;
sampling theory;
methodological research and development;
statistical and mathematical modeling; and
random processing of problems related to testing, estimation, and prediction.
Their objective in this work is to design or use techniques that provide a basis for investigating the reliability,
validity, precision of measurement, probability of inferences, and risk of error in statistical outcomes.
Statistical means of inquiry may be applicable to any area of investigation. After mathematical statisticians
develop substantive knowledge of a subject matter, they may readily transfer their professional knowledge to
another subject matter field. The methods are fundamentally the same whether the employee applies them to:
analyze physical phenomena;
design, conduct, and analyze medical experiments;
develop management control data;
examine quantitative material in economics; or
investigate other scientific fields.
The mathematical statisticians’ work assignments follow a variety of patterns. For example:
As part of research teams, they:
measure, correlate, and reduce to numerical form phenomena that is best observed using mathematical
or statistical methods; and
frequently serve as staff advisors to various subject matter specialists on the potentials and limitations of
statistical methods.
As leading statistical agency authorities, they:
make recommendations to senior officials on interpreting multiple, conflicting, or incomplete data;
advise senior officials on technical issues central to initiating new statistical programs or major
revisions to current statistical programs;
research new sampling and/or estimation techniques for statistics;
publish state-of-the-art statistical study findings; and
make presentations at professional meetings and conferences.
In collecting data, they:
serve as program technical advisors;
design or adapt mathematical and statistical tools;
develop methods and select techniques that other statisticians and/or subject matter specialists use;
conduct methodological research to improve sample surveys or experimental designs; and
conduct evaluations of data collection, reduction, processing, and analysis methodologies.

Occupational Information (continued)
As consultants and mathematical statistical analysts, they:
develop or review sampling plans and all the essential elements of sample design, including:
o determining sample size;
o allocating optimum total sample size to strata or clusters;
o specifying methods of sample selection and estimation; and
o measuring the magnitude and direction of bias, if any; and
conduct research and development to improve the design and performance of sample surveys,
experimental designs, and clinical trials, including:
o applying mathematical statistical theory, techniques, and methods to statistical studies and surveys;
o analyzing the accuracy and validity of prior statistical data;
o determining if planned operations and processes are appropriate;
o recommending improvements for collecting and analyzing statistical data;
o preparing and disseminating technical documentation of work;
o being on the forefront of developing new statistical methods and performing cutting edge research
to solve statistical problems; and
o developing and conducting statistical computing research involving record linkage, time series
modeling, seasoned adjustment, and demographic forecasting.
In conducting mathematical statistical research, in contrast to subject matter research, mathematical
statisticians help to develop new, or improve existing, statistical theories and techniques.

Occupational Information (continued)
Survey Statisticians
A survey is a scientific method of gathering information from a sample of individuals, households, firms,
institutions, or other units of analysis so that results can be generalized to the entire population. The validity of
survey results depends on selecting the sample so that each unit has a measurable chance of selection and
collecting information using standardized, replicable procedures. Survey statisticians apply statistical theories
and techniques to:
plan, organize, and operate programs for collecting, verifying, adjusting, processing, summarizing,
analyzing, and presenting information numerically; and
conduct research to evaluate data quality.
Survey statisticians collect primary data from original sources and secondary data from records, instruments, or
reports established for historical, administrative, regulatory, or quality control purposes. They also select or
sample data.
Although the decisions of survey statisticians rest on a sound foundation of statistical principles, they also
require other specialized knowledge.
The responsibilities of survey statisticians involve the following:
defining useful measurements for specific purposes;
determining the best and most efficient ways to collect quantitative information;
determining the feasibility of reducing a problem to one in which objective measurements can be taken;
planning, organizing, and overseeing the operation of a survey;
selecting the most appropriate survey methods within cost considerations;
devising measurement methods to assess the completeness of a survey sampling universe;
devising surveys or processes that will capture the missing elements in a survey sampling universe;
developing procedures to ensure that the sampling universe for repetitive surveys are kept up to date;
developing or reviewing questionnaires, instructions, and schedules to ensure structural soundness;
planning the development of related data for comparison;
establishing systems of classification and coding;
organizing a reporting system on a production basis;
establishing the sequence of collection, summarization, and representation;
planning necessary quality checks and controls;
solving statistical problems that occur in survey collection and summarization processes;
reducing the survey process as far as possible to a routine that support personnel can manage;
establishing procedures for data storage and retrieval;
planning data dissemination systems; and
conducting in-depth analysis of data and disseminating the results of those analyses.
In some situations, a single statistician may be responsible for the entire survey process. In other situations,
particularly with large statistical organizations, survey statisticians may specialize in particular functions such as
survey planning, data collection, data processing, or data analysis and dissemination as described below:
Survey Planning – involves developing and formulating overall plans for complete surveys or parts of
surveys by using general objectives and methods. In survey planning, statisticians develop:
overall procedures;
forms design;
cost estimates;

Occupational Information (continued)
activity and time schedules;
timetables;
specific plans for quality control and production control systems;
staff requirements;
general data collection specifications;
general data processing requirements;
general survey documentation;
particular statistical methods and techniques applicable to the subject matter involved; and
statistical software and computer programs to perform analysis of statistical data and findings.
Data Collection – involves establishing general data collection specifications that translate into detailed,
practical plans for data collection systems. In data collection, statisticians:
write training manuals, procedural manuals, and related materials;
design scientific instruments and procedures governing the administrative and technical features of the
data collection system;
plan and implement pretesting plans for survey instruments; and
estimate and control budgetary and financial, supply and space, human resources, public relations, and
other general administrative management requirements of the data collection system.
Statisticians can perform the actual data collection phase of the survey in compliance with all previous plans
and procedures, quality checks appropriate for the particular survey, and troubleshooting methods applicable
to problems in the field. Their assignments typically include responsibility for explaining:
unexpected data or trends; and
inconsistent survey findings.
Data Processing – involves establishing general processing specifications that translate into detailed,
practical plans for data processing systems. In data processing, statisticians:
design large systems to control incoming data collection materials; and
develop plans for production management that include staffing plans, procedures, backlog scheduling,
and programming for tabulation methods.
Data Analysis and Dissemination – involves interpreting findings to draw substance and meaning from
them and planning statistical publications where knowledge of statistical presentation (e.g., tabulation,
classification, and charting techniques) is a paramount requirement. In data analysis and dissemination,
statisticians:
conduct statistical analyses of data using appropriate statistical methodologies;
summarize initial data;
review, analyze, coordinate, and/or revise statistical reports, volumes, and releases; and
consolidate published or publishable statistical research and writings into complete documents or books
such as statistical compendia (
Statistical Abstract or Historical Statistics).
The proper technical documentation of the statistical methods statisticians use is an essential part of data
publication and requires professional knowledge and understanding of the statistical principles that serve as a
basis for surveys.
In all of these activities, survey statisticians preserve the statistical validity intended in the original survey design
and must exercise professional knowledge of pertinent statistical principles and techniques.

STATISTICS, 1530 (continued)
Occupational Information (continued)
Statisticians
Statisticians may use data derived from a probability sample. They are usually responsible for the design, size,
and characteristics of the probability samples that are necessary to ensure the reliability of data.
Statisticians may provide advice or be directly involved in collecting primary data. They examine data collected
by others to help them understand its implications and limitations for the problem under study. Further,
statisticians evaluate data collection and statistical methodologies, and develop better data collection methods.
Statisticians organize data into a format that facilitates the required analysis and communicates the results to data
users. The organization of data takes different forms depending upon the problem under investigation. For
example, if one is interested in changes over time, statisticians present the data in a different manner than when
one is interested in the current period’s totals. The problem may involve comparing data easily with masses of
similar data and analyzing differences, or developing complex models to support in-depth analysis of data,
illustrate and interpret findings, and disseminate findings to a variety of constituents.
Statistical functions are numerous and vary extensively, but fully qualified statisticians are typically able to
determine:
whether the problem is amenable to statistical inquiry;
kinds of data needed;
necessary data sources;
new or improved methods for obtaining data, and their estimated cost and limitations; and
the most appropriate methods for analyzing and interpreting data.
Statisticians are responsible for:
analyzing findings, evaluating the statistical limitations of available data, and specifying the range of
logically possible explanations of the findings;
discovering the meaning of facts; and
presenting original or derived data in their most pertinent form, which may include text, graphs, charts,
tables, and models.
These responsibilities require knowledge of:
statistical theory;
statistical methods and techniques; and
statistical software and computer programs to perform computer analysis of statistical data and findings.

STATISTICS, 1530 (continued)
Occupational Information (continued)
Some statisticians apply statistical theory and methods to solve problems in a subject matter field. To ensure
effectiveness, statisticians must acquire considerable knowledge not only about the detail but also about the
theory of the subject under study. The work requires that they become familiar with both the general and the
specific knowledge of the field. They must understand the:
general magnitude and characteristics of the subject under study;
various categories of data;
technical language involved;
major controlling factors in the field and their general relationships;
cycles, trends, sources, validity, limitations, and interrelationships of the data involved;
need for selecting facts to quantify, and determining which are relevant, important, or extraneous;
agency programs and objectives and the special and continuing problems involved; and
data collection mechanisms and limitations.
Statistical techniques apply to any subject matter field in which numerical expression may represent the facts. In
applied statistics the statistician uses these techniques to solve specific problems requiring quantitative data or
problems inherent in selecting, collecting, analyzing, interpreting, and presenting such information. The
statistician seeks to derive meaningful relationships from data, and/or to measure the significance of quantified
data usually relating to a particular subject matter field.
Examples of the various kinds of statistical techniques that statisticians use include:
analysis of frequency distributions;
analysis and modeling of multivariates;
sampling;
analysis of variance;
determining confidence limits; and
estimating magnitudes.
A high order of judgment is required in adapting or applying appropriate techniques and interpreting results.
Such judgment is necessary to initially determine whether a problem is amenable to statistical inquiry and to
formulate and plan the entire investigation.

Distinguishing Among the Covered Occupations
Mathematical Statistics, 1529, versus Mathematics, 1520
Mathematical statistics differs from mathematics in the following areas:
concentration on the body of mathematical theory related to probability and inference; and
mathematical processes and techniques associated with statistics.
Mathematical Statistics, 1529, versus Statistics, 1530
Mathematical statistics differs from statistics in the following areas:
focus on mathematical techniques and methods of the statistical process; and
scope of mathematical theory necessary to the job function.
Mathematical statisticians design statistical tools. They are concerned less with applying statistical techniques than
with the usefulness of statistical tools in terms of the quality, reliability, and validity of the data they yield.
Impact of Automation
Automation greatly affects the way mathematical and statistical products and services are delivered. Many
mathematical and statistical professionals do scientific computation and data reduction work that involves
translating mathematical equations into compatible computer programs. Techniques that lend themselves well to
information technology include:
computer simulations;
optimization;
matrix methods;
ordinary and partial differential equations;
Monte Carlo methods; and
Boolean Algebra.
The information technology tools involved and the skill required to use them generally replace or supplement work
previously done manually or by machines. Automation does not change the primary purpose of the work or the
paramount knowledge required to do the work, which is a professional knowledge of mathematics, statistics, or
actuarial science. Properly classifying positions in these occupations is based on the relevant knowledge and skills
required to do the professional mathematics, statistics, and/or actuarial duties of the position.

Additional Occupational Considerations
Some positions may include professional work requiring knowledge and skills typically associated with the
Mathematical Science Group, 1500. In some cases, a closer look at the work may reveal that classification to a
series in this job family may not be always be appropriate. The
General Series Determination Guidelines section
of this JFS offers guidance on selecting the most appropriate series.
The following table provides examples of work that is similar to that performed in the 1500 job family, but not to
the extent that the paramount knowledge required, the reason for the position’s existence, the mission and/or
function of the organization, and the recruitment source for the best qualified candidates would warrant
classification to a series in this JFS.

Crosswalk to the Standard Occupational Classification
The Office of Management and Budget requires that all Federal agencies that collect occupational data use the
Standard Occupational Classification (SOC) system for statistical data reporting purposes. The Bureau of Labor
Statistics uses SOC codes for the National Compensation Survey and other statistical reporting. OPM and other
Federal agencies maintain a “crosswalk” between OPM authorized occupational series and the SOC codes to serve
this need. This requirement and these SOC codes have no effect on the administration of any Federal human
resources management system. The information in this table is for information only and has no direct impact on
classifying positions covered by this job family standard. The SOC codes shown here generally apply only to
nonsupervisory positions in these occupations. As changes occur to the SOC codes, OPM will update this table.
More information about the SOC is available at

PART II – GRADING INFORMATION
Part II provides grading information for use in determining the appropriate grade of
nonsupervisory two-grade interval professional positions in the Mathematical Sciences Group,
1500. These grading criteria are applicable to General Schedule positions classified under chapter
51 of title 5, United States Code. They may also be used as appropriate to determine work levels
for other Federal position classification systems. You will find more complete instructions for
evaluating positions in the following OPM publications: Introduction to the Position
Classification Standards and The Classifier’s Handbook.
How To Use This Grading Information
Evaluate positions on a factor by factor basis using the factor level descriptions (FLDs) provided
in this standard. Compare each factor in the position description to the appropriate FLDs and
illustrations. If the factor information in the position description fully matches an FLD for the
series and specialty, you may assign the level without reviewing the illustrations. FLDs are
progressive or cumulative in nature. For example, each FLD for Factor 1 – Knowledge Required
by the Position encompasses the knowledge and skills identified at the previous level. Use only
designated point values.
The FLDs in this standard cover nonsupervisory positions at grades GS-5 through GS-15.
Evaluate supervisory, leader, test and evaluation, research grants, and research positions by
applying the appropriate functional guide.
Use the occupation- and specialty-specific factor illustrations following the FLDs as a frame of
reference for applying factor level concepts. Do not rely solely on illustrations in evaluating
positions, because they reflect a limited range of actual work examples. The level of work
described in some illustrations may be higher than the threshold for a particular factor level. If the
factor information in the position description fails to fully match a relevant illustration, but does
fully match the FLD, you may still assign the level.
For each factor, record the factor level used, the points assigned, and relevant comments on the
Position Evaluation Summary Worksheet. Convert the total points to a grade using the Grade
Conversion Table, and record the grade in the Summary section of the Worksheet. The shaded
portions of the table reflect the most commonly found grades in this job family.

FACTOR 2 SUPERVISORY CONTROLS
This factor covers the nature and extent of direct or indirect controls exercised by the supervisor,
or a designated individual, over the work performed, the employee’s responsibility, and review of
completed work. The controls apply to both how supervisors assign and review work. The
supervisor determines what information the employee needs to perform the assignments (e.g.,
instructions, priorities, deadlines, objectives, and boundaries). Review controls may range from
detailed inspection of work in progress, to simply confirming that the work adheres to agency
policy. The employee’s responsibilities complement the supervisory controls (e.g., if the
supervisor does not establish the sequence in which the work is to be done, it becomes an
employee responsibility). The primary components of this factor are presented below in three
categories: How Work Is Assigned, Employee Responsibility, and How Work Is Reviewed.
NOTE: These factor level descriptions (FLDs) apply to all 1500P occupational series in this JFS.
Level 2-1 25 Points
FLD
How Work Is Assigned – The supervisor or a delegated alternate assigns work that consists of routine
requirements and developmental tasks designed to prepare the employee for higher level work. They provide:
detailed instructions on how to use and select specific methods, procedures, and techniques; and
deadlines and priorities.
Employee Responsibility – The employee:
performs work as instructed;
consults with the supervisor or designated employee when clarification of instructions is necessary; and
receives guidance on problems and work methods not specifically covered by the original instructions.
How Work Is Reviewed – The supervisor or a delegated alternate closely checks work in progress and work
results for accuracy, and evaluates the employee’s rate of development. As the employee progresses
professionally and becomes more competent in certain work areas, the supervisor gradually relaxes control over
work in progress, but continues to closely review and evaluate the work for accuracy.
Level 2-2 125 Points
FLD
How Work Is Assigned – The supervisor or designated employee instructs the employee on work objectives
and its scope, limitations, expected deadlines, and priorities. The supervisor may provide more detailed
instructions when assigning work of a type that the employee has not previously done.
Employee Responsibility – The employee:
uses initiative in carrying out recurring assignments;
works independently, but within the framework the supervisor established;
conforms with established practices and prescribed procedures; and
refers problems not covered by the instructions or guides to the supervisor for help or a decision.
How Work Is Reviewed – The supervisor or designated employee:
reviews completed work closely to verify accuracy and conformance to policy or procedural requirements
and any special instructions;
reviews findings and conclusions to ensure they are supported by facts; and
reviews in detail the more difficult work that the employee has not previously done.
Professional Work in the Mathematical Sciences Group, 1500 September 2005
U.S. Office of Personnel Management
38
Level 2-3 275 Points
FLD
How Work Is Assigned – The supervisor or designated employee outlines or discusses possible problem areas
and defines objectives, plans, priorities, and deadlines. Assignments have clear precedents requiring successive
steps in planning and execution.
Employee Responsibility – The employee:
independently plans and carries out assignments in conformance with accepted policies and practices;
adheres to instructions, policies, and guidelines in exercising judgment to resolve commonly encountered
work problems and deviations; and
brings controversial information or findings to the supervisor’s attention for direction.
How Work Is Reviewed – The supervisor or designated employee:
provides assistance on controversial or unusual situations that do not have clear precedents;
reviews completed work for conformity with policy, the effectiveness of the employee’s approach to the
problem, technical soundness, adherence to deadlines, and accomplishment of objectives; and
performs limited review of the methods used to complete the assignment.
Level 2-4 450 Points
FLD
How Work Is Assigned – The supervisor outlines available resources and overall objectives of the work. The
employee and supervisor, in consultation, discuss scope of the assignment, approaches, timeframes, and
possible execution phases.
Employee Responsibility – The employee:
plans and carries out the assignment;
resolves most of the conflicts that arise;
coordinates the work with others as necessary;
interprets policy and regulatory requirements;
keeps the supervisor informed of progress and potentially controversial problems, concerns, and issues;
develops changes to plans and/or methodology; and
provides recommendations for improvements to meet program objectives.
How Work Is Reviewed – The supervisor reviews completed work for soundness of overall approach,
adherence to requirements, achievement of expected results, and the feasibility of recommendations. The
supervisor usually does not review methods used.
Professional Work in the Mathematical Sciences Group, 1500 September 2005
U.S. Office of Personnel Management
39
Level 2-5 650 Points
FLD
How Work Is Assigned – The supervisor provides administrative direction for projects in terms of broadly
defined missions or functions of the agency.
Employee Responsibility – The employee:
is responsible for a significant agency or equivalent level program or function;
defines objectives;
interprets policies promulgated by authorities senior to the immediate supervisor and determines their effect
on program needs;
exercises a wide degree of independent professional discretion and judgment; and
independently plans, designs, and carries out the work to be done.
How Work Is Reviewed – The supervisor:
reviews work for potential impact on broad agency policy objectives and program goals;
normally accepts work as being technically authoritative; and
normally accepts work without significant change.

FACTOR 3 GUIDELINES
This factor covers the nature of guidelines and the judgment employees need to apply them. The
availability of specific, applicable guidelines may vary with individual assignments; thus, the
judgment employees use similarly varies with the assignment. The existence of detailed plans
and other instructions may make innovation in planning and conducting work unnecessary or
undesirable. However, in the absence of guidance provided by prior agency experience with the
task at hand or when objectives are broadly stated, the employee may use considerable judgment
in developing an approach or planning the work. The following are examples of guidelines used
in professional work in the Mathematical Sciences Group, 1500:
Agency regulations, directives, procedures, rulings, and initiatives
Legislation and requirements covering program operations (e.g., Employee Retirement Income Security Act,
Social Security Act, Retirement Protection Act)
Data merging system documentation
Professional association and private sector standards of practice, conduct, procedures, and certification (e.g.,
American Hospital Association, Blue Cross Blue Shield)
Military directives
Agency developed systems performance, testing, and life cycle management handbooks, specifications, and
instructions
Agency developed technical manuals and standard operating procedure guidance (e.g., statistical analysis, cost
analysis/estimating, auditing, optimization, design of experiments, quality assurance, and mathematical
modeling)
Computer software and hardware manuals
Precedent data, studies, models, and cases
Tables, charts, forms, and maps (e.g., life expectancy, properties, interest rates, productivity, mileage)
Guidelines, circulars, and regulations of other agencies and organizations such as the Office of Management
and Budget, Office of Personnel Management, Department of Labor, Department of the Treasury, Pension
Benefit Guaranty Corporation, Internal Revenue Service, and functional regulations (e.g., the Federal
Acquisitions Regulations)
Files and records, such as previous audit reports
Technical reports (e.g., reports of capabilities, performance, effectiveness, test results)
Treaties (e.g., U.S. Canada Salmon Treaty)
Established data collection, sampling, investigative, and examining procedures
Traditional budgetary practices, procedures, and policies
Do not confuse guidelines with the knowledge described under Factor 1 – Knowledge
Required by the Position. The primary components of this factor are: Guidelines Used and
Judgment Needed.
NOTE: These factor level descriptions (FLDs) apply to all 1500P occupational series in this JFS.
Level 3-2 125 Points
FLD
Guidelines Used – The employee uses a number of guidelines that are directly applicable to the assignment.
Guidelines prescribe established procedures and techniques and provide clear precedents.
Judgment Needed – The employee:
uses judgment in selecting and applying the most appropriate guidelines;
determines the appropriateness and applicability of any minor deviations within existing guidelines; and
refers to the supervisor situations to which the existing guidelines cannot be applied or that require
significant deviations.
Professional Work in the Mathematical Sciences Group, 1500 September 2005
U.S. Office of Personnel Management
41
Level 3-3 275 Points
FLD
Guidelines Used – The employee uses a wide variety of reference materials and manuals; however, they are not
always directly applicable to the work, or they have gaps in specificity. Precedents are available outlining the
preferred approach to more general problems or issues.
Judgment Needed – The employee is expected to apply guidelines accurately and articulate the reasons for
modifying specific guidelines to address unusual situations.
Level 3-4 450 Points
FLD
Guidelines Used – The employee uses guidelines and precedents that are very general regarding agency policy
statements and objectives. Guidelines specific to assignments are often scarce, not applicable, or have gaps in
specificity that require considerable interpretation and/or adaptation for application to issues and problems.
Judgment Needed – The employee uses judgment, initiative, and resourcefulness in deviating from established
methods to:
modify, adapt, and/or refine broader guidelines to resolve specific complex and/or intricate issues and
problems;
deal with specific issues or problems;
research trends and patterns;
develop new methods and criteria; and/or
propose new policies and practices.
Level 3-5 650 Points
FLD
Guidelines Used – The employee uses guidelines such as broad policy statements, basic legislation, recent
scientific findings, or reports that are often ambiguous and require extensive interpretation.
Judgment Needed – The employee uses considerable judgment and ingenuity and exercises broad latitude to:
determine the intent of new or revised guidelines;
develop policy and guidelines for specific areas of work; and
interpret policy statements, regulations, and methods development plans.

FACTOR 5 SCOPE AND EFFECT
This factor covers the relationships between the nature of work; i.e., the purpose, breadth, and
depth of the assignment, and the effect of work products or services both within and outside the
organization. Effect measures whether the work output facilitates the work of others, provides
timely services of a personal nature, or impacts the adequacy of research conclusions. The concept
of effect alone does not provide sufficient information to properly understand and evaluate the
impact of the position. The scope of the work completes the picture allowing consistent
evaluations. Only consider the effect of properly performed work. The primary components of
this factor are: Scope of the Work and Effect of the Work.

FACTOR 6 PERSONAL CONTACTS
AND
FACTOR 7 PURPOSE OF CONTACTS
These factors include face-to-face and remote dialogue – e.g., telephone, email, and video
conferences – with persons not in the supervisory chain. (Personal contacts with supervisors are
under Factor 2 – Supervisory Controls.) The levels of these factors consider the work required to
make the initial contact, difficulty of communicating with those contacted, the setting in which the
contact takes place, and the nature of the discourse. The setting describes how well the employee
and those contacted recognize their relative roles and authorities. The nature of the discourse
defines the reason for the communication and the context or environment in which the
communication takes place. For example, the reason for communicating may be to exchange
factual information or to negotiate. The communication may take place in an environment of
significant controversy and/or with people of differing viewpoints and goals.
Only credit points under Factors 6 and 7 for contacts that are essential for successfully performing
the work and that have a demonstrable impact on its difficulty and responsibility. Factors 6 and 7
are interdependent, so use the same personal contacts to evaluate both factors.
Determine the appropriate level for Personal Contacts and the corresponding level for Purpose of
Contacts. Obtain the point value for these factors from the intersection of the two levels as shown
on the Point Assignment Chart at the end of this section.
NOTE: These factor level descriptions (FLDs) apply to all 1500P occupational series in this JFS.
PERSONAL CONTACTS
Level 1
Other professionals, technicians, and support personnel in the immediate office or related units
within the agency. Limited contact with employees outside the office.
Level 2
Employees in the same agency, professionals and specialists from related occupations, and/or
members of the general public in a moderately structured setting. Typical contacts are:
scientists and engineers;
military personnel;
client organization representatives.
Level 3
Individuals or groups inside and outside the employing agency representing high levels of
organizations internal and external to the Federal Government. Typical contacts are:
management officials or senior technical staff of corporations;
medical and legal professionals;
contractors; and
State and local officials;
Government, academia, and professional organizations;
representatives of Congressional committees.
Level 4
High ranking officials from outside the employing agency at national or international levels in
highly unstructured settings. Typical contacts are:
members of Congress or their professional staffs/representatives;
leading officials of foreign Governments; and
Presidential advisors and/or cabinet level appointees of major departments and agencies;
State governors and mayors of large cities or their professional staffs/representatives;
presidents of large national or international firms; or
leaders of national stakeholder and/or interest groups.

Purpose of Contacts
Level A
To obtain, clarify, or exchange information or facts needed to complete an assignment.
Level B
To plan, coordinate, or advise on work efforts or to resolve issues or operating problems. Contacts
involve influencing or persuading people who have a cooperative attitude and goals in common
with those of the employee. Contacts typically involve identifying options for resolving problems.
Level C
To influence and persuade persons or groups to comply with established policies or to accept
established methods. Also to negotiate or establish rapport to gain information. Contacted
personnel may be skeptical or uncooperative.
Level D
To justify, defend, negotiate, or settle matters involving significant or controversial topics. Work
usually involves active participation in conferences, meetings, hearings, or presentations.
Problems or issues are of such considerable consequence or importance that they are not
susceptible to resolution at lower echelons in Government. Persons contacted typically have
diverse scientific approaches, viewpoints, goals, or objectives. The employee must achieve a
common understanding of the problem and a satisfactory solution by persuasion, compromise, or
developing suitable alternatives.

Scope of the Work – Work involves serving as a consultant to high level officials and counterparts in other
agencies, educational institutions, professional associations, and Governments. The mathematical statistician
works on projects of general interest and significance to the Government (e.g., endangered wildlife species).
Work requires:
conducting extensive applications in time series analysis, sampling, analysis of variance, etc., to resolve
critical agency problems;
ensuring proper interpretation and implementation of technical recommendations by drafting proposed
legislative changes to a critical agency program or system;
planning, developing, and directing major programs where the analysis and original studies are of such major
importance and scope that extremely large data sources or legislative coordination is required; and
representing the agency or command at conferences, briefings, and meetings concerning long-range goals,
state-of-the-art technology, or the advantages or disadvantages of various complex methods.
Effect of the Work – Work has ongoing, far reaching implications and may be the basis for evaluating the
sustainability of major programs. The employee provides technical leadership that affects numerous industries
(e.g., fisheries, lumber), political activist groups, nations, treaties, natural resources, wildlife, and general
populations. Work attracts attention from others in the scientific community seeking to make comparisons or
develop similar tools.

PART III – EXPLANATORY MATERIAL
KEY DATES AND MILESTONES
In 1998, the Office of Personnel Management (OPM) notified agencies that we were continuing an
earlier effort to develop a Job Family Position Classification Standard for Professional Work in the
Mathematical Sciences Group, 1500. We had suspended the earlier effort because of a lack of
staffing resources. The 1500 occupational group includes the Computer Science Series, 1550. We
excluded the 1550 series from the effort because we believed it might be better aligned with the
Information Technology Group, 2200. The 1550 series will be the subject of a separate study to
determine its final disposition.
In conjunction with the study, we conducted factfinding at 15 installations representing collectively
10 major agencies. After completing the factfinding, we developed a draft job family standard (JFS)
which we released electronically in 2001 for agency review, comment, and test application. At that
time, we arranged with those agencies that had the largest covered populations to take the primary
role in reviewing and commenting on the draft. OPM calls this arrangement the “lead agency”
approach. In addition to the lead agencies, we invited and encouraged all agencies to comment on
the draft. This appendix addresses concerns expressed by reviewing agencies and describes our
responses to them. It also provides information that may help agencies to manage transition from
cancelled occupational standards to this JFS.
Another important milestone is that many Federal “white collar” positions are no longer evaluated
by the General Schedule grading criteria. In recognition of this situation, OPM now defines series
without a prefix of GS (e.g., series GS-1501 is now shown as 1501). We have also changed the
format of this JFS to support those users who do not classify positions according to the General
Schedule. Part I contains occupational information that is applicable to Federal work covered by the
JFS without regard to pay plan or classification system. Part II provides grading information for
positions classified according to the General Schedule grade definitions in chapter 51 of title 5,
United States Code. Part III explains the development of this standard.
RESULTS OF AGENCY REVIEW, COMMENT, AND TEST APPLICATION
A. JOB FAMILY STANDARDS – GENERAL INFORMATION. During the development of this
job family standard (JFS), we exploited every opportunity for simplifying and streamlining its
content. We relied heavily on the help of agency subject-matter experts and human resources
management officials to do this. We also incorporated changes into this JFS based on lessons we
learned from our work on earlier JFS issuances.
1. Name Changes. We changed the name of the occupational group, “Mathematics and Statistics
Group” to “Mathematical Sciences Group.” We made this change to reflect broad agency
recognition of statistics, actuarial, and mathematical work as scientific in nature. For consistency,
we also changed the designation of this job family standard to include the words, “Mathematical
Sciences Group.”

Our policy is to prescribe functional names for occupational series, and position titles for positions
performing work in that series. For example, “accounting” is a function and is the name we use for
the accounting occupation (i.e., Accounting Series, 0510). “Accountant” is the title we prescribe for
positions that involve doing work predominantly in the accounting series. Consistent with this
policy, we changed the names of three occupational series in the Mathematics and Sciences Group
as shown below.
Series Former Series Name New Series Name
1510 Actuary Actuarial Science
1529 Mathematical Statistician Mathematical Statistics
1530 Statisticia

2. Classifying Professional Scientific Work. In response to the draft of this JFS and earlier
standards, agencies requested that we provide guidance on classification issues related and perhaps
unique to professional scientific work. One specific request was that we provide instructions for
assigning functional classification codes to professional scientific positions. The guidance is
available in
The Classifier’s Handbook. As a convenience for the agencies, however, we have
incorporated the guidance into this JFS.
3. Issue – Distinguishing Between Professional and Technical Work. We have included in
this job family standard (JFS), guidance to determine whether work is professional or technical in
nature. The guidance is available in The Classifier’s Handbook. We have added the material to
this JFS in recognition of the fact that line managers and others who use it may do so infrequently.
By placing this guidance in this JFS, we eliminate the need for them to reference another document.
We believe this change in a small way contributes to the efficiency and convenience of the
classification process.
B. THE 1500 JOB FAMILY STANDARD FOR PROFESSIONAL WORK – SPECIFIC
ISSUES. When we announced this study, we requested agency comments on a number of specific
issues. This section describes those issues and provides a summary of the agency comments on
them. It also describes the actions we have taken in response to the agency comments, and the
rationale for our actions.
1. Issue – Establish a General Mathematics and Statistics Series, 1501
Agency Comments: The majority of agencies indicated a strong preference for establishing a
“miscellaneous” series for the Mathematical and Statistical Occupational Group.
Our Response: We established a miscellaneous series, the General Mathematics and Statistics
Series, 1501. This new series gives agencies the capability to appropriately classify work that
consists of a mix of mathematical, statistical, and related work. The new occupation gives agencies
a classification option that for many years has been available for other occupational groups.

2. Issue – Retaining Specialty Areas (represented by parenthetical titles) in the Statistics
Series, 1530.
Agency Comments: Most agencies commented that the existing parenthetical titles facilitate
recruitment efforts and should be retained. A couple of agencies with medical and health research
functions suggested the addition of a “Biomedical” specialty. One agency suggested combining
some of the specialties to eliminate any overlap in current specialty titles. Only one agency opposed
the use of parenthetical titles for specialty areas.
Our Response: With one exception, we retained the existing 1530 parenthetical titles. The one
exception is that we abolished the parenthetical title, “General.” We did this because we are
allowing agencies to use any basic title with the newly-established General Mathematical and
Statistic Series, 1501. The agency choice of a basic title with the 1501 series eliminates the need for
a parenthetical title, General, with the 1530 series.
We did not authorize use of a new parenthetical title, “Biomedical.” We disapproved that change
because we already authorize use of relevant parenthetical titles (e.g., Health, Biology, and
Medicine) with the 1530 series.
In response to agency comments, we clarified that agencies may apply parenthetical titles to both
Survey Statisticians as well as to Statisticians.
3. Issue - Establish Specialty Areas and Parenthetical Titles for Series in this JFS in
Addition to Those Authorized with the Statistics Series, 1530.
Agency Comments: The majority of agencies indicated that there was no need for specialty
areas/parenthetical titles for any series other than the Statistics Series, 1530.
Two agencies recommended parenthetical titles for the Mathematical Statistics Series, 1529. One of
the two agencies suggested we authorize the specialty areas and parenthetical titles defined for the
Statistics Series, 1530 for use with the series, 1529. The other agency recommended we recognize
health, biology, and medicine specialties and establish for them the related parenthetical titles,
“Biomedical Research,” “Bioinformatics,” and “Health.”
A third agency suggested we recognize specialty areas for the Operations Research Series, 1515.
The agency also recommended we establish for the specialties, the related parenthetical titles
“Various Engineering Fields,” “Ships,” “Aircraft,” “Cost Analysis,” and “Computers.
Our Response: The Introduction to Position Classification Standards provides guidance on this
issue. The guidance instructs agencies that when we do not prescribe use of parenthetical titles, or
specifically proscribe their use, agencies may append official position titles with any meaningful
parenthetical title of their choosing. We believe there is no compelling argument to rescind the
flexibility that this guidance gives to the agencies. Accordingly, we have not prescribed
parenthetical titles for series other than the Statistics Series, 1530.

4. Issue - Assessing Impact on Grades. We observed our usual practice of requesting that
agencies test the draft job family standard by applying it to actual positions. We requested also that
they report to us the impact of the draft application on the grades of tested positions.
Agency Comments: Agencies applied the draft JFS to 421 positions. They reported no grade
impact due to its application. They did report five downgrades, but acknowledged they were due to
inaccurate grade evaluations based on application of the existing standard.
In addition to grade impact, agencies indicated that the test showed the need for clearer distinctions
among factor level descriptions (FLDs) 1-7, 1-8 and 1-9 in Factor 1, Knowledge Required by the
Position. Agencies also asked for more occupation-specific illustrations.
Our Response: We made significant changes to the FLDs for Factor 1 and also (although not
specifically requested to do so) for Factor 4, Complexity. We also added a number of occupation-
specific illustrations for Factors 1 and 4, and also for Factor 5, Scope and Effect. As requested,
many of the newly-added illustrations are companion to the higher level FLDs. We believe these
changes, taken as a whole, will improve the accuracy of classification efforts.
C. THE 1500 JOB FAMILY STANDARD FOR PROFESSIONAL WORK –
MISCELLANEOUS ISSUES.
1. Issue - Distinguishing between Grade 15 and Executive Level Positions
Agency Comments: One group of reviewers suggested that many of the higher factor level
descriptions (FLDs) for several factors in this job family standard (JFS) seemed “…more descriptive
of a Senior Executive Service (SES) position than a GS position.”
Our Response: The law at 5 U.S.C. 5104 defines the criteria for all GS grade levels. Some years
ago, the Civil Service Commission (predecessor agency to the Office of Personnel Management)
developed a Primary Standard in Factor Evaluation System (FES) format to provide the
classification community with a generic tool that might be applied to positions in all occupations.
All interested parties have long accepted the Primary Standard and its FES higher factor level
descriptions (FLDs) as consistent with the law.
We prepared this JFS in FES format. When we prepared this JFS, we confirmed that its FLDs met
FLD criteria in the Primary Standard and as a consequence were in compliance with the law. We
understand and recognize that the higher FLD criteria may be quite demanding. However, we are
obligated by statute to develop standards that are consistent with the law’s current grade level
criteria. Accordingly, we have not made changes to weaken the higher FLDs in this JFS.
2. Issue – Cancellation of the Cryptography Series, 1540
We proposed canceling series, 1540 because our records showed it had no population.
Agency Comments: A few reviewers suggested that we not cancel series 1540. The reviewers
believed that a number of executive agencies used the series, but for security reasons did not report
employment in it.
U.S. Office of Personnel Management
94
Professional Work in the Mathematical Sciences Group, 1500 September 2005
Our Response: We contacted the agencies the reviewers believe employ personnel in series, 1540.
None of the contacted agencies expressed concern with our proposal to cancel the series.
Accordingly, we cancelled 1540 as a series available for general use. We have reserved the code
“1540” and the occupational series name, “Cryptography,” for use by the intelligence community.
This information will be placed in the next revision of the Handbook of Occupational Groups and
Families with a list of reserved series.
