Research on teacher churn has produced conflicting conclusions as to its impact on students and teachers. We bring clarity to this work by combining and expanding on analytical approaches used in earlier research to determine how and when different types of churn (i.e., grade, school) impact teacher effectiveness and attendance. Using data from…

Many districts and states have implemented incentives to recruit teachers to low-performing schools, and previous research has found evidence that these incentives are effective at attracting teachers. However, effects on the schools and students these teachers leave behind have not been examined. This study focuses on the spillover effects of…

We contextualize the magnitude of teacher attrition during the pandemic, including from the 2020-2021 school year to the 2021-2022 school year, using longitudinal data on teachers in Washington since the 1984-1985 school year. The teacher attrition rate after the 2020-2021 school year (7.3%) increased by almost one percentage point from the…

Theories of market-based school reform suggest that teacher labor markets may be inefficient because schools lack autonomy to incentivize performance in hiring, retention, and compensation. We test this empirically by comparing teacher exits in the deregulated market of New Orleans with neighboring traditional school districts. We find that the…

A growing body of research evaluates the effects of turnaround on chronically low-performing schools. We extend this literature by formally testing factors that may either mediate or suppress the effects of two turnaround initiatives in Tennessee: the Achievement School District (ASD) and local Innovation Zones (iZones). Using…

We examine the effect of Michigan's 2011 reforms to teacher evaluation and tenure policies on teacher retention. Our data are drawn from administrative records containing the population of public school employees from 2005-2006 through 2014-2015. To identify the causal effects of these reforms on teacher attrition, we utilize a…

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…

Nationally, 18% of principals turn over each year, yet research has not yet credibly established the effects of this turnover on student and teacher outcomes. Using statewide data from Missouri and Tennessee, we employ a difference-in-differences model with a matched comparison group to estimate arguably causal effects. We find that principal…

Informal and institutional barriers may limit teacher movement between charter schools and traditional public schools (TPSs). However, we know little about how teachers choose schools in areas with a robust charter school sector. This study uses qualitative data from 123 teachers to examine teachers' job decisions in three cities with varying…

Educators raise concerns about what happens to students when they are exposed to new or new-to-school teachers. However, even when teachers remain in the same school they can switch roles by moving grades and/or subjects. We use panel data from New York City to compare four ways in which teachers are new to assignment: new to teaching, new to…

The federal School Improvement Grant (SIG) program allocated US$7 billion over nearly a decade in an effort to produce rapid and lasting improvements in schools identified as low performing. In this article, we use a regression discontinuity design to estimate the effect of Ohio's SIG turnaround efforts on student achievement and school…

One consequence of the Great Recession is that teacher layoffs occurred at a scale previously unseen. In this article, we assess the effects of receiving a layoff notice on teacher mobility using data from Los Angeles and Washington State. Our analyses are based on 6-year panels of data in each site, including 4 years of layoffs. We find that the…

School reconstitution, a turnaround strategy that prescribes massive staffing turnover, is expected to result in more committed and capable school staff and innovative practices. However, little evidence supports this assumption. We use quasi-experimental designs to assess the impact of reconstitution on student achievement and teacher mobility,…

Retaining effective teachers is a key policy priority nationwide, particularly in districts that serve large numbers of disadvantaged students. We investigate whether a change in the Miami region's Teach for America (TFA) placement strategy was accompanied by changes in teacher attrition and mobility decisions. Our results suggest that the…

We report findings from a quasi-experimental evaluation of the recently implemented US$5,000 retention bonus program for effective teachers in Tennessee's Priority Schools. We estimate the impact of the program on teacher retention using a fuzzy regression discontinuity design by exploiting a discontinuity in the probability of treatment…
