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…

While researchers have shown great interest in understanding teacher evaluation, little is known about how teachers' actions and interactions surrounding evaluation affect the dual goals of evaluation--accountability and development. Using data collected during a yearlong ethnographic study at three schools (combined with follow-up interviews four…

Studies link principal effectiveness to lower average rates of teacher turnover. However, principals need not target retention efforts equally to all teachers. Instead, strong principals may seek to strategically influence the composition of their school's teaching force by retaining high performers and not retaining lower performers. We…

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…

We used multilevel analysis to examine the predictive validity of scores from the Framework for Teaching (FFT), the observation measure used most often to evaluate teachers' instruction. We investigated how well 81 kindergarten teachers' FFT scores for eight reading and eight mathematics lessons observed throughout the year predicted students'…

In July 2011, the State of Michigan adopted a broad set of teacher labor market reforms, including a high-stakes evaluation system designed in part to remove low-performing teachers. We examine the characteristics of teachers rated as "minimally effective" and "ineffective," as well as their schools, and the relationship…

A core motivation for the widespread teacher evaluation reforms of the past decade was the belief that these new systems would promote teacher development through high-quality feedback. We examine this theory by studying teachers' perceptions of evaluation feedback in Boston Public Schools and evaluating the district's efforts to improve feedback…

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,…

Novice teachers' professional contexts may have important implications for their effectiveness, development, and retention. However, due to data limitations, descriptions of these contexts are often unidimensional or vague. Using 10 years of administrative data from the Los Angeles Unified School District, we describe patterns of new teacher…

The federal Race to the Top initiative signified a shift in American education policy whereby accountability efforts moved from the school to the teacher level. Using administrative data from Tennessee, we explore whether evaluation reforms differentially influenced mobility patterns for teachers of varying effectiveness. We find that the rollout…

Spurred by the federal Race to the Top competition, the state of Tennessee implemented a comprehensive statewide educator evaluation system in 2011. The new system is designed to increase the rigor of evaluations and better differentiate teachers based on performance. The use of more differentiated ratings represents a significant shift in…

Given concerns with the performance and attrition of novice teachers, North Carolina allocated $7.7 million from Race to the Top to create the New Teacher Support Program (NTSP), an induction model developed and implemented by the state's public university system and targeted at low-performing schools. In this study, we assess the associations…

Policymakers are revolutionizing teacher evaluation by attaching greater stakes to student test scores and observation-based teacher effectiveness measures, but relatively little is known about why they often differ so much. Quantitative analysis of thirty schools suggests that teacher value-added measures and informal principal evaluations are…

Professional vision has been identified as an important element of teacher expertise that can be developed in teacher education. It describes the use of knowledge to notice and interpret significant features of classroom situations. Three aspects of professional vision have been described by qualitative research: describe, explain, and predict…

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…
