This study analyzed predictors of fall-to-spring and fall-to-fall retention for 9,200 first-time-in-college students who enrolled in a community college over a four-year period. Findings highlight the impact of developmental education programs and internet-based courses on student persistence. Additional predictors include financial aid, parents' education, the number of semester hours enrolled in and dropped during the first fall semester, and participation in the Student Support Services program.
