The California Formative Assessment and Support System for Teachers (CFASST) is a structured, two-year induction program for beginning teachers that is used across the state as a central component of California's Beginning Teacher Support and Assessment (BTSA) program. In 2002, the California Commission on Teacher Credentialing commissioned ETS to conduct a study of the impact of BTSA/CFASST. In this study, ETS Researchers Marnie Thompson, Pamela Paek, Laura Goe, and Eva Ponte looked at the impact of the program on the teaching practices of beginning teachers and on the learning of their students. A summary of the research study is available; detailed information on the methods and findings of the study can be found in a series of four technical reports that can be obtained from ETS.
