We use statewide data from Massachusetts to investigate teacher performance evaluations as a measure of teaching effectiveness. Schools tend to classify most of their teachers as proficient, but we document substantial variation across schools in the extent to which ratings differentiate teachers. Using event study and teacher fixed effects…

States are responsible for setting and evaluating the standards that teacher preparation programs (TPPs) must meet for accreditation. Despite the considerable investment that states make in this process, no prior research has linked the ratings of TPPs generated by program reviews to inservice teacher performance. In this paper, we describe…

In this policy brief we argue that there is little debate about the statistical properties of value-added model (VAM) estimates of teacher performance, yet, despite this, there is little consensus about what the evidence about VAMs implies for their practical utility as part of high-stakes performance evaluation systems. A review of the evidence…

Ratings are present in many areas of assessment including peer review of research proposals and journal articles, teacher observations, university admissions and selection of new hires. One feature present in any rating process with multiple raters is that different raters often assign different scores to the same assessee, with the potential for…

Fifty years after the release of "Equality of Educational Opportunity"--widely known as the Coleman Report--much of what James Coleman and his colleagues reported holds up well to scrutiny. It is, in fact, remarkable to read through the 700-plus pages and see how little has changed about what the empirical evidence says matters. The…

There are good reasons for re-thinking teacher evaluation. Evaluation systems in most school districts appear to be far from rigorous. A recent study showed that more than 99 percent of teachers in a number of districts were rated "satisfactory," which does not comport with empirical evidence that teachers differ substantially from each…

The evaluation of teachers based on the contribution they make to the learning of their students, "value-added", is an increasingly popular but controversial education reform policy. In this report, the authors highlight and try to clarify four areas of confusion about value-added. The first is between value-added information and the…

This report addresses the comparison of teacher evaluation systems in the context of a particular administrative and legislative challenge: How a state or the federal government could achieve a uniform standard for dispensing funds to school districts for the recognition of exceptional teachers without imposing a uniform evaluation system on those…

Over 2000 teachers in the state of Washington received reduction-in-force (RIF) notices in the past two years. The authors link data on these RIF notices to a unique dataset that includes student, teacher, school, and district variables to determine the factors that predict the likelihood of a teacher receiving a RIF notice. They find a teacher's…

The formula is simple: Highly effective teachers equal student academic success. Yet, the physics of American education is anything but. Thus, the question facing education reformers is how can teacher effectiveness be accurately measured in order to improve the teacher workforce? Given the demand for objective, quantitative measures of teacher…

This paper explores the politics of various types of teacher compensation reforms, with a particular focus on pay for performance. It examines the political positions taken by the nations two teachers' unions, the extent to which these reflect the preferences of teachers, and how both influence the decisions by localities to implement reforms. New…
