Research shows that the at-risk population entering college dropout or land on probation within their first year in college. Through a longitudinal comparative research design, this study examines at-risk students' academic standing, retention, graduation, and tutoring usage within a cohort program compared to a non-cohort initiative at a community college. The analysis focuses on the at-risk population, exploring community college attendance, online education, student involvement, and social and academic integration. The study yielded several insights relevant to the impact of cohort design on a comprehensive approach that includes educational and non-academic support contributing to the development of evidence-based practices to improve outcomes for at-risk students. The findings can assist in enhancing the academic success, retention, and graduation rates of at-risk students. The study results can also help policymakers and higher education institutions make informed decisions about the effectiveness and potential benefits of cohort and non-cohort programs for at-risk students.
