A narrative review was developed to add to the discussion and dissemination of research on community colleges. The review adds to existing work by synthesizing and critiquing the empirical research to date specific to three of the most prevalent programmatic efforts presently seen on community college campuses: (a) learning communities, (b) student success courses, and (c) supplemental instruction. Empirical investigations or evaluations of student success programs from academic journals, conference presentations, dissertations, unpublished policy reports, and book chapters were identified, summarized, and critiqued. The review concludes with a proposed research agenda to advance research on program effectiveness at community colleges and implications for practice. (Contains 2 tables.)
