Most states responded to the onset of the pandemic by temporarily granting teachers Emergency licenses. These licenses allowed teachers to work in classrooms without passing the typical licensure exams. Since then, several states have extended their use of Emergency licenses, raising questions about how these policies impact the composition of the…

Four-day school week (4DSW) schedules are growing rapidly across the U.S., with school districts citing perceived benefits to teacher recruitment and retention and student attendance as motivations for adopting the schedule. This study uses panel data from Colorado, one of the states with the highest prevalence of 4DSWs, to investigate the impacts…

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…

This report provides formative data about the implementation of projects associated with the Pennsylvania Bureau of Special Education's Attract, Prepare, and Retain (APR) efforts during the 2023-24 school year. We surveyed or interviewed students and educators participating in six such projects: Developing Future Special Educators Grants, APR…

This report provides data about the special education teacher pipeline in Pennsylvania and projects associated with the Pennsylvania Bureau of Special Education's Attract, Prepare, and Retain (APR) efforts. We first used administrative data from the Pennsylvania Department of Education to provide a historical portrait of the special education…

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…

We used longitudinal staffing data from Pennsylvania to explore differences in special education personnel attrition across personnel categories, individual characteristics, and district characteristics. Special education administrators and school psychologists had the highest attrition rates among special education personnel, with special…

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…
