Postsecondary enrollment consists of all students who graduated from high school in a given school year who enroll in programs of postsecondary education in the first academic year that begins after the students' graduation. Using RIDE's high school completer data along with National Student Clearinghouse's postsecondary enrollment data, RIDE determines the type of postsecondary program students have enrolled in upon graduation. For the purposes of reporting on postsecondary enrollment, a "program of postsecondary education" has the same meaning as "institution of higher education" under section 101(a) of the Higher Education Act of 1965, as amended (HEA). (34 C.F.R. § 200.36(a)(2)). Under section 101(a) of the HEA, an institution of higher education must meet specific criteria; for example, it must be accredited (or preaccredited, as specified under section 101(a)(5)), it must be a public or non-profit institution, and it must award a bachelor's degree or provide a 2-year program that is acceptable for full credit toward such a degree.
