PART and GPRA
The Government Performance and Results Act (GPRA) seeks to make the federal government more accountable to the American people for the tax dollars it spends and the results it achieves. The Department of the Interior is complying with GPRA through its performance management system that provides useful information to managers and promotes accountability for results. In addition to a strategic plan, GPRA requires agencies to prepare related annual performance plans and annual performance reports. The legal requirements for an annual performance plan are met by a performance budget. The annual performance report requirement will be fulfilled by both the performance budget and the performance and accountability report (PAR).

The OMB Summary assessment shows the scores and outline of the program.
The program enforces Federal and Tribal law on reservations by investigating criminal offenses to protect life and property. The program also provides detention and correctional facilities, officer training, and community outreach programs. Both the Bureau and Indian Tribal governments operate the program.
