The Abell Foundation commissioned this study to examine the potential of dual college enrollment and similar learning options for students enrolled in Baltimore City Public School System (BCPSS) high schools. What is the potential of dual enrollment as a strategy to improve high school completion rates, ease the transition to college for lower-achieving students, decrease the need for college remediation, and improve college graduation rates? Dual enrollment permits high school students to earn transferable college credits before graduation from high school. Multiple research studies have identified five strong predictors of college attendance and completion, particularly for minority and low-income students: academic preparation, social support, access to information, parental involvement and knowledge about college, and financial aid. This report focuses primarily on the first two elements, academics and social support. However, all five elements should be considered vital to any college transition initiative. This report provides a primer on dual enrollment, early college access, college transition and similar programs as practiced in Maryland and throughout the country. It concludes by recommending approaches that can help more youth, not just high achievers, make a successful transition to college. Appended are: (1) State Policies on Dual Enrollment; (2) Early College Access Program Comparison; (3) BCPSS Participation in Advanced Placement Program, 1994-2006 by number of AP exams taken (number of students taking exams); and (4) 2006 Dual Enrollment in BCPSS High Schools.
