Educator labor markets

Many districts and states have begun implementing incentives to attract high-performing teachers to low-performing schools.  Previous research has found that these incentives are effective.  However, effects on the schools and students these teachers leave behind has not been examined.  This study focuses on the general equilibrium effects of recruiting effective teachers to Tennessee’s Innovation Zone (iZone) schools, one of the most successful turnaround initiatives in the nation (Zimmer, Henry, & Kho, 2017).  While there is some variation in the effects of losing these teachers, we find they range between -0.04 and -0.12 standard deviations in student test score gains.  However, an estimate including both these negative effects and the positive effects in iZone schools yields overall net positive effects.

High teacher turnover imposes numerous costs on the schools and districts from which teachers depart. This study asks how schools respond to spells of high teacher turnover, and assesses organizational and human capital losses in terms of the changing composition of the teacher pool. Our analysis uses more than two decades of linked administrative data on math and ELA teachers at middle schools in North Carolina to determine school responses to turnover across different policy environments and macroeconomic climates. We find that, even after accounting for school contexts and trends, turnover has marked, and lasting, negative consequences for teacher quality and student achievement. Our results highlight the need for heightened policy attention to issues of teacher retention and working conditions.

Exploiting variation from principal and teacher transitions over long administrative data panels in Missouri and Tennessee, we estimate the effects of principal race on the hiring and turnover of racially diverse teachers. Evidence from the two states is strikingly similar. Black principals increase the probability that a newly hired teacher is Black by 5–7 percentage points. This result appears to be partially driven by principals hiring from within their networks of educators with whom they have worked before. Black principals also decrease Black teacher mobility, reducing the probability that a Black teacher changes schools by 2–5 percentage points. Increases in Black teacher hiring and reductions in turnover mean that a change from a White to a Black principal increases the fraction of Black teachers working in a school by about 3 percentage points, on average, increasing exposure of students to Black teachers. Further evidence suggests that assignment to a Black teacher increases the math achievement of Black students, though the presence of a Black principal appears to have positive impacts on Black students’ math achievement that is not explained by assignment to Black teachers.

Recruiting and retaining teachers can be challenging for many schools, especially in low-performing urban schools in which teachers turn over at higher rates. In this study, we examine three types of school-level attributes that may influence teachers’ decisions to enter or transfer schools: malleable school processes, structural features of employment, and school characteristics. Using adaptive conjoint analysis survey design with a sample of teachers from low-performing, urban, turnaround schools in Tennessee, we find that five of the seven most highly valued features of schools are malleable processes: consistent administrative support, consistent enforcement of discipline, school safety, small class sizes, and availability of high-quality professional development. In particular, teachers rated as effective are more likely to prefer performance-based pay than teachers rated ineffective. We validate our results using administrative data from Tennessee on teachers’ actual mobility patterns.

Effective teacher hiring is fundamental to improving schools and yet few studies investigate this process. In this exploratory study of six successful, high-poverty schools (three charter, three district) in one Massachusetts city, we analyze the policy contexts that influenced hiring and examine the schools’ hiring practices. Through interviews with 142 teachers and administrators, we learned that, despite significant differences, these schools’ approaches were strikingly similar. Each used a two-way, information-rich hiring process that provided schools and candidates with opportunities to exchange information and assess one another before making an offer or signing a contract. Participants viewed their investment in hiring as an essential part of their school’s success. Based on our findings, we provide recommendations for policymakers, practitioners, and researchers.

A growing body of research evaluates the effects of turnaround on chronically low-performing schools. We extend this research to formally test factors that either mediate or suppress the effects of two turnaround initiatives in Tennessee: the Achievement School District (ASD) and local Innovation Zones (iZones).  Using difference-in-differences models within a mediational framework, we find that hiring highly effective teachers and employing effective principals partially explain positive effects of iZone interventions.  In the ASD, high levels of teacher turnover suppress potential positive effects after the first year.  In iZone schools, several factors suppress even larger positive effects: hiring more novice teachers; hiring more principals with less experience; and high levels of student chronic absenteeism and student in-migration.
