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. 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 state has since adopted three TPA models: the California Teaching Performing Assessment (CalTPA), the educative Teaching Performance Assessment (edTPA), and the Fresno Assessment of Student Teachers (FAST). Unlike multiple-choice licensure exams measuring the basic skills or content knowledge of teaching candidates, TPAs are classroom-based assessments capturing direct evaluation of teaching skills. This evaluation process creates opportunities for candidates (and their preparation programs) to identify their strengths and weaknesses. TPAs typically occur when preservice candidates are in student teaching placements (referred to here as clinical practice) or, for those participating in in-service preparation like internships, in their own classrooms. Multiple studies have found that TPA scores predict effectiveness once candidates enter the classroom as licensed teachers, and proponents argue that TPAs serve as a valuable professional standard set to ensure a teaching candidate is ready to enter the classroom. On the other hand, critics have questioned whether a TPA requirement, along with other tests, serves as an unnecessary gatekeeper to the profession and whether the fees and time investment required by a TPA can be a cumbersome barrier for potential teachers, particularly teaching candidates of color and candidates with fewer financial resources. While TPA passing rates among California teaching candidates were quite high prior to the COVID-19 pandemic, variability in performance on TPAs has increased in California as the pandemic has rocked every aspect of the education system, including the training of teachers. Focusing on the 2021-22 and 2022-23 academic years, this study explored whether certain preparation experiences predicted TPA success. Understanding these relationships can inform programmatic and policy decisions about how to support teaching candidates in entering the workforce with strong preparation and minimal barriers. Using data provided by the California Commission on Teacher Credentialing, this analysis focused on 18,455 California teaching candidates who took either the CalTPA or edTPA--the two widely available TPAs used across California teacher preparation programs--between September 1, 2021, and August 31, 2023.
