Researchers and policymakers often assume that teacher turnover harms student achievement, but recent evidence calls into question this assumption. Using a unique identification strategy that employs grade-level turnover and two classes of fixed-effects models, this study estimates the effects of teacher turnover on over 600,000 New York City 4th…

Despite the long history of the study of pedagogical content knowledge (PCK), two facts remain obvious.

Although little empirical work on peer tutoring has focused specifically on retained students, the literature suggests that those students who act as peer tutors often experience…
