This research report, accompanying brief and fact sheet from the Learning Policy Institute examine statewide patterns that emerge from the responses of almost 60,000 completers of teacher preparation programs (TPPs) across California who applied for their preliminary teaching credentials in 2016–17 to 2020–21. The data also include perceptions from employers hiring these new teachers and the cooperating teachers working with student teachers during their preparation. The report describes who is receiving preliminary teaching credentials after completing California-based TPPs, how well prepared completers of TPPs feel across all of the domains of the teaching performance expectations, what kind of coursework and clinical experiences they received, and what aspects of preparation explain how prepared completers feel to enter the profession.
