The Department of Education's Office of Federal Student Aid (FSA) manages the Free Application for Federal Student Aid (FAFSA), which students and parents submit to determine a student's eligibility for receiving financial aid. The FAFSA Processing System (FPS)--the system that underpins federal student aid--processes these applications. In December 2023, FSA, the largest provider of student financial aid in the nation, deployed a new system with limited functionality to process student aid applications. However, the system--FPS--had availability issues, recurring errors, and long wait times that affected students' ability to receive aid. Since then, FSA has continued to work to deploy additional functionality. Among other things, this report addresses the extent to which FSA conducted selected contract oversight activities and applied leading systems testing practices. The Government Accountability Office (GAO) examined how FSA tracked the contractor's progress in meeting contract requirements and compared FSA actions to established contract oversight processes and agency standards. GAO also identified key contract oversight staff for FPS and compared federal certification and training requirements against relevant documentation for these staff. In addition, GAO compared the actions taken by FSA to leading practices for system testing.
