INTRODUCTION 

The Handbook of Occupational Groups and Families provides agencies with a starting point to 

classify positions. For additional information, please refer to the Introduction to the Position 

Classification Standards.

The Handbook of Occupational Groups and Families is divided into two parts: 

 PART I White Collar Occupational Series 

Defines occupations and lists the series names and codes used in 

classifying white collar jobs in the Federal Government. Previous 

editions of this document referred to these occupations as “General 

Schedule System Occupations.” 

 PART II Trade, Craft, or Labor Occupational Series

Defines occupations and lists the occupation names and codes used in 

classifying trade, craft or labor jobs in the Federal Government. 

Previous editions of this document referred to these occupations as 

“Federal Wage System Occupations.” 

GLOSSARY 

TERM DEFINITION

Classification Standard Classification standards are issued by OPM to relate the grade level definitions 

in title 5 to specific work situations and thereby provide the basis for assigning 

to each position the appropriate title, series, and grade. (Source: Introduction

to the Position Classification Standards, TS-134, July 1995) 

Federal Wage System 5 U.S.C. 5102 (c)(7) exempts from coverage under the General Schedule those 

“employees in recognized trades or crafts, or other skilled mechanical crafts, or 

in unskilled, semi-skilled, or skilled manual-labor occupations, and other 

employees including foremen and supervisors in positions having trade, craft, 

or laboring experience and knowledge as the paramount requirement.” Such 

positions are covered by the Federal Wage System. 

Flysheet Flysheets provide some information about a series and may suggest standards 

and guides to use for determining grade levels under the General Schedule or 

Federal Wage System, but include no grade level criteria. 

Functional Guide and 

Standards 

Functional guides and functional standards are used to determine the grade of 

broad categories of Federal work classified under the General Schedule (GS) 

Classification System and the Federal Wage System (FWS), respectively. 
Handbook of Occupational Groups and Families May 2009 

U.S. Office of Personnel Management 4

General Schedule The classification system covered by chapter 51 of title 5. It includes a range of 

levels of difficulty and responsibility for covered positions from grades GS−1 

to GS−15. It is designated by “GS” for positions at all of these grade levels. 

(Source: Introduction to the Position Classification Standards, TS-134, July 

1995) 

Job Family (for Trade, 

Craft and Labor) 

A job family is a broad grouping of trades, craft, and labor occupations related 

in one or more ways such as: similarity of functions performed, transferability 

of knowledge and skills from one occupation to another, or similarity of 

materials or equipment worked on. (Source: Federal Wage System Job 

Grading System, TS-44, Sep 1981) 

Job Family Standard (for 

White Collar) 

A Job Family Standard (JFS) covers a group of related white collar occupations 

or series. (Source: The Classifier’s Handbook, TS-107, Aug 1991) 

Occupational Group A major category of white collar occupations, embracing a group of associated 

or related occupations; e.g., the Accounting and Budget Group, GS−0500; the 

Engineering and Architecture Group, GS−0800; the General Administrative, 

Clerical, and Office Services Group, GS−0300). (Source: Introduction to the 

Position Classification Standards, TS-134, July 1995) 

Series A subdivision of an occupational group or job family consisting of positions 

similar as to specialized line of work and qualification requirements. Series are 

designated by a title and number such as the Accounting Series, 0510; the 

Secretary Series, 0318; the Microbiology Series, 0403. (Source: Introduction 

to the Position Classification Standards, TS-134, July 1995) 

Trade, Craft, and Labor 

Occupations 

If a position clearly requires trades, craft, or laboring experience and 

knowledge as a requirement for the performance of its primary duty, and this 

requirement is paramount, the position is in a trade, craft, or labor occupation 

regardless of its organizational location or the nature of the activity in which it 

exists. (Source: Introduction to the Position Classification Standards, TS134, July 1995) 

White Collar 

Occupations 

A position is considered white collar, even if it requires physical work, if its 

primary duty requires knowledge or experience of an administrative, clerical, 

scientific, artistic, or technical nature not related to trade, craft, or manual-labor 

work. (Source: Introduction to the Position Classification Standards, TS134, July 1995)

General Information

• This handbook does not provide grading criteria. For positions classified under the 

General Schedule, position classification standards and job family standards provide 

grading criteria. Job grading standards provide grading criteria for trade, craft, and 

labor positions classified under the Federal Wage System. 

• A single asterisk (*) in this handbook indicates a published position classification 

standard or job grading standard exists for that series. Two asterisks (**) indicate a 

flysheet exists for that series. Three asterisks (***) indicate a published job family 

position classification standard exists for that series. 

• For additional information regarding the classification of positions as Professional, 

Administrative, Technical, Clerical, or Other (PATCO), please refer to the 

Introduction to the Position Classification Standards, TS-134, July 1995). 

• Series which are underlined are hyperlinked to the corresponding standard for 

convenience. 

• All agencies may use any occupational series in Parts I and II of this handbook.

This series covers positions that involve the management, administration, or operation of a safety 

and occupational health program or performance of administrative work concerned with safety 

and occupational health activities and includes the development, implementation, and evaluation 

of related program functions. The primary objective of this work is the elimination or

principles, standards, and techniques of safety and occupational health management; and (2)

work. The positions require technical rather than professional knowledge and abilities for full 

performance and, therefore, do not require education and training equivalent in scope and nature 

to that required for professional positions in community planning.

PART II 

Outline of Position Classification Plan for 

Trade, Craft, or Labor Job Families and Occupations 

Note: Because of the scope and variety of Federal Government operations, and the continuing 

changes taking place in occupations, a separate occupation is not always established for each 

identifiable line of work. The “01” code in each job family, therefore, is designated as a general 

code, and is used for jobs which cannot be identified with an established occupation within the 

family but which can be identified with the family itself. For additional guidance on the use of the 

“01” code see the Introduction to the Federal Wage System Job Grading System.
