Teaching performance assessments (TPAs) can be used to assess the readiness of potential teachers because they require candidates to provide evidence of their planning and teaching skills through classroom videos accompanied by commentaries Ensuring that teaching candidates are well prepared to enter the classroom is a critical mission for teacher preparation programs and state agencies that approve programs and set teacher licensure standards. Teaching performance assessments (TPAs) can be used to assess the readiness of potential teachers because they require candidates to provide evidence of their teaching knowledge and skills through classroom videos, lesson plans, student work, and analysis of teaching and learning. Multiple studies have found that TPA scores predict effectiveness once candidates enter the classroom as licensed teachers. TPAs have been adopted in at least 16 states as a requirement of either teacher preparation program completion or initial licensure. California, the focus of this study, was one of the first states to adopt a TPA as a licensure requirement for beginning teachers. The report on which this brief is based explored whether certain preparation experiences predicted success on the California Teaching Performance Assessment (CalTPA) or the educative Teaching Performance Assessment (edTPA), the two widely available TPAs used across California preparation programs. Focusing on the 2021-22 and 2022-23 school years, this analysis examined whether TPA success for more than 18,000 California teaching candidates varied by preparation pathway, program, and the nature of preparation experiences as reported by respondents on the annual survey administered to all those completing preparation and applying for their preliminary teaching credential with the California Commission on Teacher Credentialing (CTC).
