Using a literature review taxonomy described by Cooper and Hedges (2009), an analysis of 32 publicly available studies of late registrations was conducted to provide researchers and policymakers with an assessment of the extent, quality, and major findings of the studies. The reviewer asserted that few high-quality studies have been conducted on late registration, and the research does not provide strong evidence that late registration is associated with poor student outcomes. The review provided answers to the following questions: What does the body of research on late registration indicate about the advisability of retaining it as an option for students? What research methods--and of what quality--have been employed? What research remains to be done? What are the implications for policy and college operations?
