T his report provides an overview of statutory inspectors general (IGs) in the federal government, including their structure, functions, and related issues for Congress. Establishment of Statutory IGs

Statutory inspectors general (IGs) are intended to be independent, nonpartisan officials who prevent and detect waste, fraud, abuse, and mismanagement within federal departments and agencies. To execute their missions, IGs lead offices of inspector general (OIGs) that conduct audits, investigations, and other evaluations of agency programs and operations and produce recommendations to improve them. Issues for Congress

Statutory IGs play a key role in government oversight, and Congress plays a key role in establishing the structures and authorities to enable that oversight. The structure and placement of IGs in government agencies allows OIG personnel to develop the expertise necessary to conduct in-depth assessments of agency programs. Further, IGs' dual reporting structure—to both agency heads and Congress—positions them to advise agencies on how to improve their programs and policies and to advise Congress on how to monitor and facilitate such improvement. Congress, therefore, may have an interest in ensuring that statutory IGs possess the resources and authorities necessary to fulfill their oversight roles. As the federal government continues to evolve, so too does the role of IGs in government oversight. Agency programs and operations have increased in breadth, complexity, and interconnectedness. Consequently, IGs may face increasing demand to complete statutorily mandated reviews of programs and operations that require (1) a broader focus on program performance and effectiveness in addition to waste, fraud, and abuse; (2) analysis of specialty or technical programs, possibly in emerging policy areas; and (3) use of more complex analytical methods and tools. Congress may consider several options regarding IG structures, functions, and coordination as the role of IGs in government oversight evolves.
This report provides an overview of statutory inspectors general (IGs) in the federal government, including their structure, functions, and related issues for Congress.
Statutory IGs—established by law rather than administrative directive—are intended to be independent, nonpartisan officials who aim to prevent and detect waste, fraud, and abuse in the federal government. To execute their missions, IGs lead offices of inspector general (OIGs) that conduct various reviews of agency programs and operations—including audits, investigations, inspections, and evaluations—and provide findings and recommendations to improve them. IGs possess several authorities to carry out their respective missions, such as the ability to independently hire staff, access relevant agency records and information, and report findings and recommendations directly to Congress.
