Three years into the COVID-19 pandemic era, concerns about teacher turnover and teacher shortages remain at the top of the education agenda. But contrary to media reports about a "wave of resignations and retirements" (e.g., Heller, 2021), early evidence from state databases showed a more nuanced picture: teacher attrition was actually…

We use a novel database of student teaching placements in Washington State to investigate teachers' transitions from student teaching classrooms to first job classrooms and the implications for student achievement. We find first-year teachers are more effective when they teach in the same or an adjacent grade, in the same school type, or in a…

This policy brief summarizes the responses by early-career science, technology, engineering and math (STEM) teachers in Washington State to the Washington STEM Teacher Survey. These early-career STEM teachers were asked about their perspectives of their teacher education program (TEP) and STEM subject preparation, with a focus on their student…

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…

We use a novel database of the preservice apprenticeships ("student teaching placements") of teachers in Washington State to investigate the relationship between mentor effectiveness (as measured by value added) and the future effectiveness of their mentees. We find a strong, positive relationship between the effectiveness of a teacher's…

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…

We used survey and administrative data from Washington State to assess the degree to which special education teacher preparation, district literacy instructional practices, and the alignment between preparation and practice were associated with the reading test score gains of students with high-incidence disabilities taught by early-career special…

We use longitudinal data from North Carolina and Washington to study the extent to which four processes--teacher attrition from each state workforce, teacher mobility within districts, teacher mobility across districts, and teacher hiring--contribute to "teacher quality gaps" (TQGs) between advantaged and disadvantaged schools. We first…

We utilize detailed teacher-level longitudinal data from Washington State to investigate patterns of teacher mobility in districts with different collective bargaining agreement (CBA) transfer provisions. Specifically, we estimate the log odds that teachers of varying experience and effectiveness levels transfer out of their schools to other…

We use a novel database of the preservice apprenticeships ("student teaching placements") of teachers in Washington State to investigate the relationship between mentor effectiveness (as measured by value added) and the future effectiveness of their mentees. We find a strong, positive relationship between the effectiveness of a teacher's…

Effective teachers make a real difference for student learning. But research shows that both in Massachusetts and nationwide, academically struggling students and those from historically low performing subgroups are less likely to be assigned to the teachers who are most likely to generate strong results. This results in missed opportunities to…

Policymakers aiming to close the well-documented achievement gap between advantaged and disadvantaged students have increasingly turned their attention to issues of teacher quality. A number of studies have demonstrated that teachers are inequitably distributed across student subgroups by input measures, like experience and qualifications, as well…
