Permitting students to transfer credits earned in one program towards another program lies at the heart of the BC post-secondary transfer system, maximizing student mobility through credit portability. This study focused on situations where students seek to apply credits to multiple credentials that are "lateral" (for example, where a student with a marketing diploma seeks to earn another business diploma) or "reverse" (for example, where a student with a social work degree seeks to earn a certificate in addictions). The study examined only undergraduate credentials and posed the following questions: (1) To what extent, and in what ways, do public post-secondary institutions in BC allow students to use credit that they have already applied towards earning one credential as credit towards another credential at the same or lower level?; (2) What policies and practices currently govern the awarding of credit for multiple credentials, and how readily available are these?; (3) To what extent are institutional policies consistent across the province, and where do they vary?; and (4) What issues are raised by the practice of allowing the same credit to be used in multiple credentials, and how might the BC public post-secondary system best address these issues? To answer these questions, the authors conducted a literature review, gathered data on current policies and practices published on a sample of institutional websites, conducted interviews with institutional personnel, and collected background policy documentation.
