Title IV of the Higher Education Act (HEA; P.L. 89-329), as amended, authorizes programs that provide financial assistance to students to attend certain institutions of higher education (IHEs). In academic year (AY) 2016-2017, 6,760 institutions were classified as Title IV eligible IHEs. Of these IHEs eligible to participate in Title IV programs, approximately 29.4% were public institutions, 27.8% were private nonprofit institutions, and 42.9% were proprietary (or private, for-profit) institutions. It is estimated that $122.5 billion was made available to students through Title IV federal student aid in FY2017. This report provides a general overview of HEA provisions that affect a postsecondary institution's eligibility for participation in Title IV student aid programs. It first describes general eligibility criteria at both the institutional and programmatic level and then, in more detail, the program integrity triad. Next, it discusses several issues that are closely related to institutional eligibility: Program Participation Agreements, campus safety policies and crime reporting required under the Clery Act, the return of Title IV funds, and distance education.
