Teachers’ evaluations in many states include information about their students test score gains. In this paper, we describe the assumptions that are required for teacher value-added (TVA) estimates to be treated as unbiased causal effects. We compare commonly used TVA models on policy-relevant criteria using simulated data in which the assumptions of unconfounded assignment of students and teachers and no peer effects are violated and with actual data. The three-level hierarchical linear performs best when either assumption is violated. For year-to-year consistency, the dynamic ordinary least squares model performs best. A common policy goal – identifying the lowest performing quintile of teachers—can be done with reasonable accuracy but between 3.2 and 9.3 percent of all teachers are misclassified.
