Historically, Community College has been the gateway to higher education for many students regardless of their background or academic achievement level. Perhaps this may explain why the retention rates at Community Colleges are consistently lower than four-year institutions. Only 29% of full-time degree seeking Community College students graduate within three years of their initial enrollment (McFarland et al., 2017). Although several programs have been implemented to increase retention, few studies have addressed how effective these strategies are at Community College. Using data from Florida Community College, this causal-comparative study examined the effects of a Summer Bridge (SB) course on student success outcomes. Also, this study explored how the effects varied by gender and ethnicity. The sample (N = 1735) was comprised of two groups: a cohort of first-time, full-time degree-seeking students who were enrolled in SB during Summer 2015 and a matched comparison group who enrolled the following term, Fall 2015. Findings revealed a statistically significant difference between the two groups on academic integration by gender and ethnicity. Results suggest that participation in Summer Bridge promotes integration into the academic and social system of the college which increases the chance of students persisting to graduation. Although findings revealed a statistically significant difference between the groups on success indicators, no causal link can be established. Further in-depth investigation into the effects of enrolling in a SB course using an experimental design with a qualitative component is warranted.
