WG-2500 through WG-9000 Job Listings

The government’s Personnel Classification System includes Wage Grade occupations grouped into families of like jobs. The 36 occupational families range from WG-2500 to WG-9000. Each occupational family has its own group number and title which makes it distinctive from every other family grouping. The following is a list of the Wage Grade families with links to current job vacancies.

There were 192,520 federal wage grade workers employed in this group as of March 2016 of which 1,236 work overseas in foreign countries. Most cabinet level agencies and some large and small independent agencies employ wage grade workers. The largest employers are the Departments of the Army, Navy, Air Force, and Defense with 136,069 civilians employed.

Each occupational family has a three-part identifier: the Pay System, Occupational Group Number, and Title. In the example WG-2500, Wire Communications Equipment Installation and Maintenance Family, WG means the job is in the Wage Grade Schedule (or blue collar) pay system; 2500 is the Occupational Family Number; and Wire Communications Equipment Installation and Maintenance is the Occupational Family Title. Each occupational family lists the individual jobs that comprise the family with their corresponding Job Series Numbers and Titles. A brief description is provided for each of the occupational Wage Grade families and the jobs within that family.

Because of the scope and variety of Federal Government operations, and the continuing changes taking place in wage grade 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.

The following information is compiled from numerous federal documents including qualification standards, job announcements, career articles, occupation flysheets, FEDSCOPE, OPM, Agency websites, interviews with federal employees, The United States Government Manual, and from the Department of Labor’s Occupational Outlook Handbook.
