Objective: This study seeks to expand understanding of transfer student capital (TSC), including sources of TSC and how TSC is used by community college transfer students to navigate transfer to a public, 4-year institution. Method: Using the TSC framework, a descriptive case study design was employed. Data sources include 17 transfer student interviews, eight observations of pre-transfer meetings between students and advisors, and a review of documents. Data were analyzed inductively and deductively using a pattern matching coding technique. Results: Family and peers appear to be the most common way that students gain TSC to navigate the transfer process. High schools also provide critical transfer information to students. Transfer advisors and faculty either at community colleges or 4-year colleges sometimes provide important transfer information but serve in a critical role of building students' self-efficacy for transfer rather than merely passing along transfer information. Contributions: This study indicates that high schools, family members, and peers are influential sources of TSC, in addition to previously well-understood sources, such as community college faculty and transfer advisors. This study introduces a new term, "self-efficacy for transfer'" and offers an expanded TSC conceptual model.
