Efforts to attract and retain effective educators in high-poverty public schools have had limited success. Dallas ISD addressed this challenge with information produced by its evaluation system to offer large, compensating differentials to highly effective teachers willing to work in its lowest-achievement schools. The Accelerating Campus…

The onset of the pandemic in spring 2020 substantially disrupted routes into teaching and offered a unique opportunity to study this process with different requirements for initial entry into the classroom. We examine the impacts of the Temporary Certificate of Eligibility (Temporary CE), which allowed teacher candidates in New Jersey to enter the…

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…

The success of many students with disabilities (SWDs) depends on access to high-quality general education teachers. Yet, most measures of teacher value-added measures (VAM) fail to distinguish between a teacher's effectiveness in educating students with and without disabilities. We create two VAM measures: one focusing on teachers' effectiveness…

We use publicly available, longitudinal data from Washington state to study the extent to which three interrelated processes--teacher attrition from the state teaching workforce, teacher mobility between teaching positions, and teacher hiring for open positions--contribute to "teacher quality gaps" (TQGs) between students of color and…

We study the impact of a bonus policy implemented by Hawai'i Public Schools starting in fall 2020 that raised the salaries of all special education teachers in the state by $10,000. We estimate that the introduction of this policy reduced the proportion of vacant special education teaching positions by 32%, or 1.2 percentage points, and the…

Prior research has connected characteristics of cooperating teachers who supervise student teaching to performance measures of the teacher candidates they host, suggesting more effective teachers may also be better mentors. The specific measures of cooperating teacher effectiveness considered in this prior literature (value added and performance…

Teacher turnover has adverse consequences for student achievement and imposes large financial costs for schools. Some have argued that high-stakes testing may lower teachers' satisfaction with their jobs and could be a major contributor to teacher attrition. In this paper, we exploit changes in the tested grades and subjects in Georgia to study…

Two recent CALDER studies published in "Exceptional Children" provide new evidence about special education teacher preparation and its implications for students with disabilities. The first study (Theobald et al., 2021) shows that special educators who received dual endorsements in special education and another subject had lower rates of…

In this research brief, the authors present evidence on how the diversity of the teacher workforce changes as "prospective" teachers advance through the teacher pipeline: tracking from 12th grade students as some obtain the education and certifications required to be eligible to teach in public schools, and some apply to and are hired…

We examine how teachers from two alternative preparation programs--Teach for America (TFA) and Kansas City Teacher Residency (KCTR)--contribute to the teacher labor market in and around Kansas City, Missouri. We show that TFA and KCTR teachers are more likely than other teachers to work in charter schools, and more broadly, in schools with high…

Traditionally, teacher salaries have been determined solely by experience and educational attainment. This has led to chronic shortages of teachers in particular subject areas, such as math, science and special education. We study the first long-running statewide program to differentiate teacher pay based on subject area, Georgia's bonus system…

We use data on the teacher preparation experiences and workforce outcomes of more than 1,300 graduates of special education teacher education programs in Washington to provide a descriptive portrait of special education teacher preparation, workforce entry, and early career retention. We find high rates of workforce entry for special education…

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…
