These are the appendices for the technical report, "An Investigation of the Comparability of Commission-Approved Teaching Performance Assessment Models." California's Commission on Teacher Credentialing (Commission) requires all programs of preliminary multiple and single subject teacher preparation to use a Commission-approved Teaching Performance Assessment (TPA) as one of the program completion requirements for prospective teacher candidates. Three TPA models were approved by the Commission: (1) the FAST (Fresno Assessment of Student Teachers), owned and operated by California State University, Fresno (Fresno State); (2) the edTPA, owned by Stanford University, with an operational contractor of the Evaluation Systems group of Pearson; and (3) the CalTPA (California Teaching Performance Assessment), originally developed by Educational Testing Service (ETS) and owned by the Commission, revised by a Design Team with an operational contractor, also of the Evaluation Systems group of Pearson. The Commission contracted with the Human Resources Research Organization (HumRRO) to conduct an independent investigation of the comparability of the three TPA models. The investigation occurred between June 2017 and December 2019. Appendices include documentation, surveys, and rubrics. [For Volume I: Technical Report, see ED613793.]
