This study examines student retention using Astin’s Input-Environment-Output model of assessment. Using administrative data, binomial logistic regression was performed to identify factors for successful student retention of first year, full-time, First-degree entrants at a Caribbean university. The odds of being retained were highest for scholarship recipients and female students. Living on campus was found to reduce one’s odds of being retained. The number of courses passed in high school and age were found to be statistically significant. The study adds to the literature on student retention by examining students in the Caribbean, and confirms the importance of financial aid to student retention. Future research will examine the relationship between academic preparation and retention.
