Purpose: This article examines the literature on the transfer function in American higher education, and it reviews three primary dimensions of transfer: (a) the transfer function and pathways, (b) transfer access and experiences, and (c) state transfer policy. Argument: This literature review engages core transfer concepts and we argue that the literature is dominated by the vertical transfer pathway, despite multiple transfer pathways and definitions. The research also suggests that students' transfer experiences and outcomes are not equal, institutional cultures and policies are not designed to support diverse students, and the inadequate transfer structures and policies need to be reformed to improve transfer outcomes for students of color, low-income students, and first-generation students. Finally, we argue that the nature and distribution of state transfer policies is uneven and the impact of state transfer policies on student outcomes is mixed, so we know little about their efficacy. Conclusion: We conclude the article with a set of priorities for future transfer research that address gaps and limitations of the existing literature.
