In 2013, the Chicago Board of Education closed 47 elementary schools, directly affecting 13,000 students and 900 teachers. The closures created employment uncertainty for closed-school teachers, and this article investigates the labor market consequences for teachers. We employ a difference-in-differences approach that compares the exit rates of closed-school teachers with teachers in schools that only experienced threat of closure. We estimate that the closures resulted in a near doubling of teacher exit among teachers in closed schools, particularly among low-performing teachers. We also find that, among closed-school teachers, Black teachers were more likely to return than White teachers. Given the nationwide trend of school closures for budgetary or performance reasons, this article has implications for strategic retention of effective teachers.
