OPM's oversight responsibility began over 125 years ago with the passage of the Civil Service Act of 1883. Even though there have been many changes in organizations, agencies, Presidential administrations, and personnel systems, our statutory oversight responsibility remains today.
Consistently, the Civil Service Commission (up until the 1978 Civil Service Reform Act) and the U.S. Office of Personnel Management (established as part of the Civil Service Reform Act of 1978) provides the statutory responsibility to maintain oversight of the Federal personnel system.
OPM's statutory responsibility to oversee the Federal personnel system encompasses assessment of compliance with merit system principles, and supporting laws, rules, regulations, Executive Orders, and OPM standards, as well as the effectiveness of personnel policies, programs, and operations.
The legal authority for OPM oversight is 5 U.S.C. 1104(b) (2) and 5 CFR, Part 5 and 10 discuss OPM regulations for enforcement, corrective action, and agency responses to corrective action.
