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 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...

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...

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...
