Approximately 30% of students who enter the postsecondary education system do so through 2-year colleges. The majority of these students intend to earn a bachelor's degree, but most leave college before earning a diploma from a 4-year institution. The discrepancy between bachelor's degree aspirations and degree attainment rates of students who enter through 2-year colleges suggests that vertical transfer students--those who transfer from 2- to 4-year colleges--face unique obstacles to academic performance and retention that affect their likelihood of earning a bachelor's degree. Similar barriers exist for economically disadvantaged students, who may be more likely to enter the postsecondary education system through 2-year colleges. This scoping review synthesizes the literature on factors influencing economically disadvantaged vertical transfer students' academic performance in the first year posttransfer and retention between the first and second year posttransfer. Implications for 2- and 4-year institutions and recommendations for future research are discussed.
