Transfer student success is an increasingly important subject in higher education policy circles in recent years, and for good reason. Almost half of undergraduates attending Maryland's public four-year institutions transfer from the state's community colleges. However, transfer students complete bachelor's degrees at notably lower rates than their counterparts starting at four-year institutions. Improving transfer student outcomes will be integral to meeting the goal of 55% or more of Marylanders holding at least an associate degree by 2025. This policy brief explores the challenges transfer students experience and provides evidence-based policy recommendations by summarizing the findings from rigorous empirical research on the subject.
