At a time when student loan debt continues to mount for many, the Public Student Loan Forgiveness (PSLF) program--established in 2007 and administered by Education--is intended to encourage individuals to pursue careers in public service. Senate Report 116-48 included a provision for the Government Accountability Office (GAO) to study the effectiveness of the PSLF program at promoting military and civilian recruitment and retention as well as military readiness. This GAO report assesses the extent to which: (1) Department of Defense (DOD) personnel pursue and receive loan forgiveness through the PSLF program; (2) Education has shared information with DOD officials and its military and civilian personnel about the program; and (3) DOD uses the program for recruitment and retention to promote readiness. GAO analyzed student loan data from Education and the PSLF servicer from the beginning of the program through January 2020; reviewed relevant laws, documents, and other information related to PSLF, benefits, recruitment, retention, and readiness; and interviewed DOD and Education officials. GAO is making five recommendations to increase information sharing about the PSLF program. These include that DOD provide information to its personnel and issue guidance to its officials about the program, and that Education and DOD collaborate to share information about the program. Education concurred and DOD partially concurred with the recommendations, which GAO continues to believe are valid, as discussed in the report.
