1. Government Performance and Results Act of 1993, Public Law 103-62. Section 2, "Findings and Purposes," (b) Purposes. This section explicitly lists the purposes of the Act.
Purpose (3): "improve Federal program effectiveness and public accountability..." (Supports that D is a purpose).
Purpose (4): "help Federal managers improve service delivery..." (Supports that A is a purpose).
Purpose (6): "improve internal management of the Federal Government." (Supports that B is a purpose).
The text does not list "providing instructions on program reporting" as a foundational purpose.
2. U.S. Government Accountability Office (GAO). (2011). MANAGING FOR RESULTS: GPRA Modernization Act Provides Opportunities to Help Address Government's Fiscal, Performance, and Management Challenges. GAO-11-466T. Page 3. The report summarizes the original purposes of GPRA, stating it was intended to "improve federal program effectiveness and public accountability... help federal managers improve service delivery... and improve internal management." This reaffirms that A, B, and D are core purposes.
3. Office of Management and Budget (OMB). (2023). Circular No. A-11, Preparation, Submission, and Execution of the Budget. Part 6, Section 200.2. This document, which provides the detailed instructions for implementing GPRA, states its purpose is to "provide instructions on performance management and strategic reviews to implement the GPRA Modernization Act of 2010." This shows that the instructions are provided in OMB guidance, separate from the foundational purposes of the Act itself.
