Institutional collaborations between community colleges and baccalaureate-degree granting universities are becoming an increasingly popular strategy to improve transfer and degree completion outcomes. Many promising cases of these collaborative efforts are described in the literature, and draw attention to some of their critical components. However, fewer resources are available to inform the process of developing transfer partnerships. This Data Note draws upon qualitative findings from the High-Performing Transfer Partnerships (HPTP) study to explore many of the factors and conditions that can impact the creation and sustainability of transfer partnerships.
