Several decades of research using school administrative data show that teacher quality is inequitably distributed across schools. But these estimates may understate teacher-related inequities if they do not account for how teacher vacancies or late hires are distributed across schools. We investigate these hiring issues using data on a direct…

We use administrative panel data from seven states covering nearly 3 million students to document and explore variation in "academic mobility," a term we use to describe the extent to which students' ranks in the distribution of academic performance change during their public schooling careers. On average, we show that student ranks are…

While spring of 2020 introduced virtual instruction to all public schools, virtual schooling had already been growing in most states. We focus on pre-COVID-19 changes to full-time virtual school enrollment in public schools, and provide evidence on the relationship between virtual school enrollment, internet speed, community demographics, and…

Prior work on teacher candidates in Washington State has shown that about two thirds of individuals who trained to become teachers between 2005 and 2015 and received a teaching credential did not enter the state's public teaching workforce immediately after graduation, while about one third never entered a public teaching job in the state at all.…

Teacher attrition is squarely in the policy spotlight. Major news outlets have featured recent stories highlighting the impact of the COVID-19 pandemic on teacher shortages. In this brief, the authors frame the magnitude of teacher attrition during the pandemic, including from the 2020-2021 school year to the 2021-22 school year, using publicly…

While spring of 2020 introduced virtual instruction to all public schools, virtual schooling had already been growing in most states. We focus on pre-COVID-19 changes to fulltime virtual school enrollment in public schools, and provide evidence on the relationship between virtual school enrollment, internet speed, community demographics, and…

We use comprehensive administrative data from three states to document the relationships between geographic mobility and student outcomes during K-12 schooling. We focus specifically on "nonstructural" mobility events--which we define as school or district changes that do not occur naturally as the result of planned transitions between…

One of the unfortunate consequences of the COVID-19 pandemic is that the sharp downturn in tax revenues, in the absence of a federal bailout, likely foretells unprecedented cuts in state and local budgets. This will in turn mean large cuts in teaching positions across the country; indeed, some projections suggest that the number of teacher layoffs…

There is growing interest in using measures of teacher applicant quality to improve hiring decisions, but the statistical properties of such measures are not well understood. We use unique data on structured ratings solicited from the references of teacher applicants to explore the dimensionality of measures of teacher applicant quality and the…

A growing quantitative literature finds evidence that student teaching placements predict later outcomes of teacher candidates and their students, but there is little large-scale quantitative evidence about the mechanisms for these estimated relationships. We use data from a survey of STEM teachers in Washington State to better understand how…

Empirical evidence shows that disadvantaged students tend to have less-qualified and less-effective teachers than their more-advantaged peers. These teacher quality gaps (TQGs), which have existed for decades and across many measures of student disadvantage and teacher quality, are an important factor explaining student achievement gaps between…

We exploit within-teacher variation in the years that math and reading teachers in grades 4-8 host an apprentice ("student teacher") in Washington State to estimate the causal effect of these apprenticeships on student achievement, both during the apprenticeship and afterwards. While the average causal effect of hosting a student teacher…

Purpose: A burgeoning literature investigates the importance of student teaching placements for teacher candidate development, but an important perspective that is largely missing from the existing literature is that of the school districts that host student teachers. In this paper, we describe the student teaching process from the perspective of…

There is empirical evidence of substantial heterogeneity in economic mobility across geographic areas and the efficacy of schools has been suggested as an explanatory factor. Using administrative microdata from seven states covering nearly 3 million students, we explore the potential role of schools in promoting economic mobility by estimating…
