    GS-1500 - MATHEMATICS AND STATISTICS GROUP   

This group includes all classes of positions the duties of which are to advise on, administer, supervise, or perform research or other professional and scientific work or related clerical work in basic mathematical principles, methods, procedures, or relationships, including the development and application of mathematical methods for the investigation and solution of problems; the development and application of statistical theory in the selection, collection, classification, adjustment, analysis, and interpretation of data; the development and application of mathematical, statistical, and financial principles to programs or problems involving life and property risks; and any other professional and scientific or related clerical work requiring primarily and mainly the understanding and use of mathematical theories, methods, and operations.

Throughout the following information, an asterisk (*) stands for series with a published standard and a double asterisk (**) stands for series with a published flysheet.

Series in this group are:

GS-1510 - Actuary Series*

This series includes positions that involve the application of professional knowledge and experience in actuarial science (including mathematics, statistics, and business, financial, and economic principles) to programs or problems related to annuities, and to life, health, or property risks and contingencies.

GS-1515 - Operations Research Series*

This series includes positions that involve professional and scientific work requiring the design, development and adaptation of mathematical, statistical, econometric, and other scientific methods and techniques to analyze problems of management and to provide 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 rather than in the subject matter of the problem.

GS-1520 - Mathematics Series*

This series includes all positions the duties of which are to advise on, administer, supervise, or perform work that requires professional education and training in the field of mathematics. This work includes research on basic mathematical principles, methods, procedures, techniques or relationships; the development of mathematical methods in the solution of a variety of scientific, engineering, economic and military problems, where the exactitude of the relationships, the rigor and economy of mathematical operations, and the logical necessity of the results are the controlling considerations.

GS-1521 - Mathematics Technician Series*

This series includes all classes of positions the duties of which are to supervise or perform work in the reduction and computation of quantitative data where such work requires the use of mathematical techniques in connection with particular engineering and scientific activities, but does not require professional knowledge of the mathematical theories, assumptions, or principles upon which the techniques are based.

GS-1529 - Mathematical Statistician Series*

This series includes all classes of positions the primary duties of which are to advise on, administer, or perform professional work requiring the design, development and adaptation of mathematical methods and techniques to statistical processes, or research in the basic theories and science of statistics.

GS-1530 - Statistician Series*

This series includes all classes of positions the duties of which are to administer or perform professional work, or to provide professional consultation in the application of statistical theories, techniques and methods to the gathering and/or interpretation of quantified information.

GS-1531 - Statistical Assistant Series*

This series includes positions that require primarily the application of knowledge of statistical methods, procedures, and techniques, to the collection, processing, compilation, computation, analysis, editing, and presentation of statistical data. The work does not require the application of professional knowledge of statistics or other disciplines.

GS-1540 - Cryptography Series

This series includes all classes of positions the duties of which are to advise on, administer, supervise, or perform research or other professional and scientific work in the construction and solution of codes and ciphers, or in the design, construction, inspection, testing, operation, and maintenance of new and improved cryptographic code and cipher equipment and methods.

GS-1541 - Cryptanalysis Series

This series includes all classes of positions the duties of which are to supervise or perform subordinate technical work in the solution or analysis of secret communication codes and ciphers.

GS-1550 - Computer Science Series**

This series includes professional positions that primarily involve the application of, or research into computer science methods and techniques to store, manipulate, transform or present information by means of computer systems. The primary requirements of the work are: (1) professional competence in applying the theoretical foundations of computer science, including computer system architecture and system software organization, the representation and transformation of information structure, and the theoretical models for such representations and transformation; (2) specialized knowledge of the design characteristics, limitations, and potential applications of systems having the ability to transform information, and of broad areas of applications of computing that have common structures, processes, and techniques; and (3) knowledge of relevant mathematical and statistical sciences.

GS-1599 - Mathematics and Statistics Student Trainee Series

See the series definition for the General Student Trainee Series, GS-0099.
