Exploring the Ancillary Benefits of Residency and Differential Staffing Programs–Glass Frog Solutions July 13, 2020 Recent research from Glass Frog Solutions looks at the ancillary benefits of residency and differential staffing programs. Residency programs are teacher preparation programs that provide experiential training to residents by placing them in classrooms with host teachers, as a part of a comprehensive teacher preparation curriculum. This research explores whether, by placing an additional adult (i.e., a resident) in the classroom, there are also positive, short-run benefits for student learning. Glass Frog uses data on three teacher residency programs across the country to explore whether hosting a resident in the classroom improves student learning, as measured by improved teacher effectiveness scores (TES), relative to teachers who do not host residents in their classrooms. The research finds evidence that having a resident in the classroom can improve student learning, with TESes being higher for host teachers at two programs.
