Using the 1996–98 Beginning Postsecondary Students Longitudinal Study, this report describes short-term enrollment in postsecondary education: departure within three years of students' first entry into postsecondary education without earning a credential and without returning. The analyses include exploration of factors associated with departure and the reasons students themselves gave for departure among students who began at public 4-year, private not-for-profit 4-year, and public 2-year institutions.
