The purpose of the paper is to provide evidence that the Transfer System in British Columbia (BC) has been effective and therefore accountable for the public funding that supports that system. The paper attempts to show: (1) the multi-faceted nature, breadth and depth of research that has been conducted to determine the effectiveness of the BC Transfer System and the success of transfer students; (2) the longitudinal nature of some elements of that research; (3) efforts that have been made to promote innovation in the Transfer System for the benefit of students and institutions; and (4) the role that BCCAT plays in working with institutions to ensure an effective Transfer System. The paper describes the history of BCCAT and its role in the Transfer System. It presents information on key research findings in two main sections, the first dealing with transfer and the second with admissions, the two different but related emphases of BCCAT's mandate. It reviews efforts to improve the Transfer System and it concludes with a discussion of possible future research projects and strategies to further enhance the accountability of the Transfer System. The Transfer System includes 27 public and 5 private institutions. Transfer research tends to deal with all institutions in the Transfer System whereas admissions research deals with public institutions only, as the Personal Education Number (PEN), which is necessary to track student flows across institutions, is not used with students at private institutions.
