It is common knowledge that teacher quality is a key in-school factor affecting student achievement. While the quality of teaching clearly matters for how much students learn, this quality is challenging to measure. Evaluating teacher quality based on the level of their students' end-of-year test scores has been one method of assessing…

Over the past decade, states and districts have updated teacher evaluation systems in response to federal incentives, such as waivers to No Child Left Behind and grants from Race to the Top. The use of multiple measures, however, raises an important issue for policymakers and practitioners: to what extent should different measures of a teacher's…

In the summer of 2013, the National Council on Teacher Quality (NCTQ) issued public, highly-visible ratings of teacher education programs as part of their ambitious and controversial Teacher Prep Review. We provide the first empirical examination of NCTQ ratings, beginning with a descriptive overview of the ratings and documentation of how they…

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…

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…

Policymakers appear increasingly inclined to utilize measures of student achievement, often state assessment results, to inform high-stakes teacher personnel decisions. This has been spurred on by the federal government's Teacher Incentive Fund (TIF) and Race to the Top (RttT) grant programs, each of which urge states and localities to tie teacher…

As part of Washington State's efforts to ensure and improve the quality of the teacher workforce, the Professional Educator Standards Board (PESB), with assistance from Educational Testing Services (ETS), has recently introduced a new, evidence-based assessment of teachers called the ProTeach Portfolio. The development of ProTeach was mandated by…

Economic theory commonly models unobserved worker quality as a given parameter that is fixed over time, but empirical evidence supporting this assumption is sparse. In this paper we report on work estimating the stability of value-added estimates of teacher effects, an important area of investigation given that new workforce policies implicitly…

This paper explores the relationship between teacher testing and teacher effectiveness using a unique data set that links teachers to their individual students. The findings show a positive relationship between some teacher licensure tests and student achievement. They also suggest that states face significant tradeoffs when they require…
