This presentation focuses on the results of an implementation evaluation of a college-wide teacher performance assessment (TPA) framework which was developed collaboratively by the College's Assessment Taskforce in 2022-2023. The assessment was implemented in 13 initial and dual certification programs in 2023-2026. The TPA framework was intentionally designed to be adapted to varied programmatic contexts, to emphasize local knowledge and expertise, to prevent a narrowing of teacher education curriculum, and to encourage innovation. The three-year implementation study consisted of investigation of implementation fidelity (based on faculty interviews and reviews of program materials), participant satisfaction (based on completer survey), and educational effectiveness (based on the analysis of assessment data). We briefly describe the results of these three-part investigation and discuss the TPA framework potential to serve multiple purposes of accountability, improvement, and innovation.
