This ex post facto study evaluated Achieving a College Education (ACE) Plus program, a credit-based transition program between a high school district and a community college. Achieving a College Education Plus is an early outreach program. It is designed to aid at-risk students in graduating from high school and making a smooth transition to higher education, while taking college courses and earning college credit. The authors examined the efficacy of Achieving a College Education Plus with respect to retention rates, graduation rates, and rate of transfer to colleges. Sixty high school students who had participated in Achieving a College Education Plus were matched to a sample of 60 non-Achieving a College Education Plus students. Archival records, postgraduate survey, and school district transcript information comprised three sources of data for this study. Using a series of logistic regression analyses to assess data and provide adequate controls for prior academic achievement, the authors determined that there were no differences in the findings with respect to gender, ethnicity, and language spoken in the home. However, statistically significant differences were found in favor of the Achieving a College Education Plus program with regard to student retention, graduation, and college enrollment. With an increasing emphasis on college readiness and student retention, this study is timely and contributes empirical data and findings to the community college literature. (Contains 4 tables.)
