Teacher Turnover, Teacher Quality, and Student Achievement in DCPS Aug 29, 2016 By James H. WyckoffMelinda AdnotThomas DeeVeronica Katz Teacher Turnover, Teacher Quality, and Student Achievement in DCPS In practice, teacher turnover appears to have negative effects on school quality as measured by student performance. However, some simulations suggest that turnover can instead have large positive effects under a policy regime in which low-performing teachers can be accurately identified and replaced with more effective teachers. This study examines this question by evaluating the effects of teacher turnover on student achievement under IMPACT, the unique performance-assessment and incentive system in the District of Columbia Public Schools (DCPS). Employing a quasi-experimental design based on data from the first years of IMPACT, we find that, on average, DCPS replaced teachers who left with teachers who increased student achievement by 0.08 standard deviation (SD) in math. When we isolate the effects of lower-performing teachers who were induced to leave DCPS for poor performance, we find that student achievement improves by larger and statistically significant amounts (i.e., 0.14 SD in reading and 0.21 SD in math). In contrast, the effect of exits by teachers not sanctioned under IMPACT is typically negative but not statistically significant.
