Shaw, BenjaminGammons, RachelPierdinock-Weed, AmberDeveloped in partnership between a University Library and a College of Information, the presenters have created and led a three-semester teacher training fellowship that prepares MLIS students for careers in academic librarianship. In celebration of the Fellowship program*s 10th anniversary, we offer reflections from a decade of research and practice, including findings from an ongoing qualitative study featuring interviews with Fellowship alumni. While this presentation focuses on our institution’s Fellowship program, the implications of our findings are relevant to anyone interested in supporting early-to-mid-career librarians as they navigate the challenges, opportunities, and future of the profession. Objective 1: Participants will be able to identify and apply effective strategies for developing and maintaining professional development programs based on a decade of insights from a student-centered fellowship program. Objective 2: Participants will learn to evaluate which components of a professional development program are most impactful for participants, drawing on qualitative findings from interviews with fellowship alumni. Objective 3: Participants will gain actionable recommendations for supporting early-to-mid career librarians in navigating career transitions, building scholarly portfolios, and fostering community-building, informed by findings from interviews with fellowship alumni.Other
