Are teachersʼ impacts on studentsʼ test scores ("value-added") a good measure of their quality? One reason this question has sparked debate is disagreement about whether value-added (VA) measures provide unbiased estimates of teachersʼ causal impacts on student achievement. We test for bias...

This paper extends the traditional test-score value-added model of teacher quality to allow for the possibility that teachers affect a variety of student outcomes through their effects on both students' cognitive and noncognitive skill. Results show that teachers have effects on skills not...

In a widely cited study, Chetty, Friedman, and Rockoff (2014a; hereafter CFR) evaluate the degree of bias in teacher value-added estimates using a novel "teacher switching" research design with data from New York City. They conclude that there is little to no bias in their estimates. Using the same...

This paper uses a new administrative dataset of students at a large university matched to courses and instructors to analyze the importance of teacher quality at the postsecondary level. Instructors are matched to both objective and subjective characteristics of teacher quality to estimate the...

We provide evidence that the robust association between cognitive skills and economic growth reflects a causal effect of cognitive skills and supports the economic benefits of effective school policy. We develop a new common metric that allows tracking student achievement across countries, over...

Growing concerns over the achievement of U.S. students have led to proposals to reward good teachers and penalize (or fire) bad ones. The leading method for assessing teacher quality is quot;value addedquot; modeling (VAM), which decomposes students' test scores into components attributed to...

This paper is the first to systematically document the relationship between individual teacher performance incentives and student achievement using United States data. We combine data from the National Education Longitudinal Survey on schools, students, and their families with our own survey...

Estimates of teacher “value-added” suggest teachers vary substantially in their ability to promote student learning. Prompted by this finding, many states and school districts have adopted value-added measures as indicators of teacher job performance. In this paper, we conduct a new test of...

This paper examines the dynamic effects of a teachers' pay for performance experiment on long-term outcomes at adulthood. The program led to a gradual increase in university education of the high school treated students, reaching a gain of 0.25 years of schooling at age 28-30. The effects on...

Over the past 15 years, labor-quality growth has been very strong—defying nearly all earlier projections—and has added around 0.5 percentage points to an otherwise modest U.S. productivity picture. Going forward, labor quality is likely to add considerably less and may even be a drag on...
