To understand the complex nature of learning recognition and credit transfer in American postsecondary education and examine the systemic barriers to entry many students face as they navigate its institutions, Ithaka S+R conducted a series of qualitative interviews in fall 2024 with state and system-level leaders in Idaho, Illinois, Ohio, and the University of North Carolina System, and representatives from Charter Oak State College and Florida International University. These semi-structured interviews were designed to probe an array of areas related to credit mobility initiatives--chief among them policy, technology, practice, and implementation--and tease out common challenges, themes, and open questions with which educational leaders continue to grapple. The case studies within this report provide the unique context for each system and institution and a descriptive overview of the policies, practices, and technologies they have employed to improve credit mobility and student outcomes. The case studies also reflect on how efforts underway at these institutions and systems align with the conceptual framework of "holistic credit mobility."
