We estimate a framework that separates these components, allowing match quality to vary with observable student characteristics and unobservable teacher-school factors. Using more than a decade of administrative data from a large urban district, we address endogenous sorting with quasi-random assignment variation induced by differences in driving time between teachers and schools. Match effects are similar in magnitude to general effectiveness. Teacher-acceptable reassignments can raise average test scores by about 0.13 standard deviations. %K teacher effectiveness %K teacher–student match effects %K assignment and sorting %K education production %K labor markets in education
