Amid heightened concerns of teacher shortages, we document the role of principals in shaping teachers’ labor market decisions. Using teacher transfer applications from a large urban school district, we find that teachers are most likely to seek transfer away from schools with less-experienced principals and weaker leadership. The qualities of principals that attract applicants are survey reports of strong leadership, applicant-principal demographic congruence, and especially having worked with the principal previously. Ultimately, schools with high rates of teacher transfer seeking and exit receive few applications per teacher vacancy. These schools are likely to have shallow applicant pools and may need district support with recruitment in the short term, with the longer-term goal of developing leaders who retain teachers.

Across an array of educational outcomes, evidence suggests that girls outperform boys on average. For example, in Chicago, ninth-grade girls earn math GPAs that are 0.29 points higher than boys on average. This paper examines explanations for this gap, such as girl-boy differences in academic preparation, behaviors and habits, and experiences in math classes. After accounting for these factors, the gender gap in math grades persists. We, then, examine the classroom-level conditions that reduce the gender gap in grades. The gap is smaller in more advanced courses like honors classes and geometry. Further, boys perform more similarly to girls in classes with male teachers. These findings highlight classroom conditions that are more conducive to the academic success of boys.

Personnel evaluation systems have historically failed to identify and remediate low-performing teachers. In 2012, Chicago Public Schools implemented an evaluation system that incorporated remediation and dismissal plans for low-rated teachers. Regression discontinuity estimates indicate that the evaluation reform increased the exit of low-rated tenured teachers by 50 percent. The teacher labor supply available to replace low-rated teachers was higher performing on multiple dimensions, and instrumental variables estimates indicate that policy-induced exit of low-rated teachers significantly improved teacher quality in subsequent years. Policy simulations show that the teacher labor supply in Chicago is sufficient to remove significantly more low-performing teachers.
