The clinical teaching experience is one of the most important components of teacher preparation. Prior observational research has found that more effective mentors and schools with better professional climates are associated with better preparation for teacher candidates. We test these findings using an experimental assignment of teacher…

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…

We investigate the predictive validity of teacher licensure tests using data from the Massachusetts Tests for Educator Licensure (MTEL). MTEL scores predict teachers' in-service performance ratings and contributions to student test scores (i.e., value added). We then explore whether these relationships vary for teacher candidates of color.…

Many prior studies have explored average differences in initial levels of teaching effectiveness among graduates from different teacher preparation programs (TPPs) and the features of preparation that predict these differences. We focus on another important dimension of effectiveness--how graduates from different TPPs improve over time. Examining…

Contemporary teacher evaluation systems use multiple measures of performance to construct ratings of teacher quality. While the properties of constituent measures have been studied, little is known about whether composite ratings themselves are sufficiently reliable to support high-stakes decision making. We address this gap by estimating the…

Our secondary analysis of Measures of Effective Teaching data contributes to growing evidence that observation ratings, used as part of comprehensive teacher evaluation systems across the nation, may measure factors outside of a teacher's performance or control. Specifically, men and teachers in classrooms with high concentrations of Black,…

There is mounting evidence of substantial "teacher quality gaps" (TQGs) between advantaged and disadvantaged students but practically no empirical evidence about their history. We use longitudinal data on public school students, teachers, and schools from two states--North Carolina and Washington--to provide a descriptive history of the…

We conducted a theory-based analysis of the underlying structure of the Tripod student perception survey instrument using the Measures of Effective Teaching (MET) database (N = 1,049 middle school math class sections; N = 25,423 students). Multilevel item factor analyses suggested that an alternative bifactor structure best fit the Tripod items,…

Teacher performance pay programs are theorized to improve student achievement by incentivizing teachers, but opponents counter that teachers are not motivated by money. We used regression discontinuity techniques and data on a census of the students, teachers, and schools in a large urban minority-majority school district to show receipt of a…

International assessments, such as the Program for International Student Assessment (PISA), are being used to recommend educational policies to improve student achievement. This study shows that the cross-sectional estimates behind such recommendations may be biased. We use a unique data set from one country that applied the PISA mathematics test…

Education agencies are evaluating teachers using student achievement data. However, very little is known about the comparability of test-based or "value-added" metrics across districts and the extent to which they capture variability in classroom practices. Drawing on data from four urban districts, we found that teachers were…
