We study the returns to experience in teaching, estimated using supervisor ratings from classroom observations. We describe the assumptions required to interpret changes in observation ratings over time as the causal effect of experience on performance. We compare two difference-in-differences strategies: the two-way fixed effects estimator common…

Teacher evaluation systems and their associated incentives have produced fairly mixed results. Our analyses are motivated by theory and descriptive evidence that accountability systems are highly racialized, and that individuals are less likely to respond to incentives when they have low expectations of success (and vice versa). Using a regression…

Teacher evaluation systems that use in-class observations, particularly in high-stakes settings, are frequently understood as accountability systems intended as nonintrusive measures of teacher quality. Presumably, the evaluation system motivates teachers to improve their practice--an accountability mechanism--and provides actionable feedback for…

The transition to new assessments aligned to the Common Core State Standards was a significant turning point in the standards' implementation. Concerns about the transition led districts to suspend the use of value-added scores for evaluating teachers, but changes to other measures, such as classroom observations, were rare. Using data from the…

Ten years ago, many policy makers viewed the reform of teacher evaluation as a highly promising mechanism to improve teacher effectiveness and student achievement. Recently, that enthusiasm has dimmed as the available evidence suggests the subsequent reforms had a mixed record of implementation and efficacy. Even in districts where there was…

Using administrative data from D.C. Public Schools, I use exogenous variation in the presence and intensity of teacher monitoring to show it significantly improves student test scores and reduces suspensions. Uniquely, my setting allows me to separately identify the effect of pre-evaluation monitoring from post-evaluation feedback. Monitoring's…
