TransferBOOST (Bachelor's Opportunity Options that are Straightforward and Transparent) is a multi-year state-level initiative developed to provide students with affordable, quality, well-supported two- to four-year pathways. On average, 43 percent of credits are lost nationwide through the transfer process. Recognizing that today's students strive to make good use of their time and money, the TransferBOOST initiative worked to ensure that credits transfer and apply seamlessly from a two-year to four-year institution. The third brief in the series shares lessons learned for higher education policymakers and practioners from the TransferBOOST initiative. The 24 institutions that worked to improve equitable transfer student outcomes during the TransferBOOST initiative have helped formulate lessons that other community college and four-year institutions, state partners for higher education, and leaders might use to increase prospective and current student trust in higher education as well as increase enrollment, retention, and completion.
