Full Abstract
Graduates of special education teacher education programs can teach in a range of special education settings, raising the potential that their training can occur in very different settings than where they find their first jobs. We follow 263 completers of Moderate Disabilities programs in Massachusetts from their field placements to their early-career teaching positions and study the characteristics of their field placements and the degree to which these are aligned with their early-career teaching positions. We also assess the degree to which alignment is associated with early-career teacher turnover. We found that many of these teachers student-taught in an inclusive setting but were hired into a self-contained special education setting and vice versa, and teachers who experienced this misalignment were more likely to leave the workforce early in their careers. Teachers who student taught with a supervising practitioner without a special education license were also more likely to leave early. Findings suggest that teachers training to educate students with learning disabilities should student teach in a setting that is aligned with where they are likely to be hired, and with a supervising practitioner who is trained in special education.

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 teacher pipeline in the state. These data provide a baseline picture of special education teachers in the state and the motivation for the APR projects. To provide formative feedback on the APR projects, we also surveyed students and educators participating in three such projects: Developing Future Special Educators Grants, Mentoring, and Learning Communities/Networking. These data provide some early evidence about how participants view their experiences with these projects.

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 in improving outcomes for SWDs, and one for non-SWDs. We find top-performing teachers for non-SWDs often have relatively lower VAMs for SWDs, and that SWDs sort to teachers with lower scores in both VAMs. Overall, SWD-specific VAMs may be more suitable for identifying which teachers have a history of effectiveness with SWDs and could play a role in ensuring that students are being optimally assigned to these teachers.

Full Abstract
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 workforce entry and retention in special education classrooms. The second study (Theobald et al., 2022) demonstrates that students with disabilities experienced greater reading gains when their district and their special education teacher’s preparation program both used/emphasized evidence-based literacy practices. Together, these papers suggest caution around state-level policies that seek to use dual licensure to address special education teacher shortages, but also suggest potential promise around better aligning special educator literacy preparation and practice as a policy lever for improving reading outcomes for students with disabilities. Future research could study specific policy interventions to design dual-license programs, address special educator shortages, and better align special educator preparation and practice.

Full Abstract
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 education teachers in grades 4-8. These students tended to have larger reading gains when their district emphasized evidence-based literacy decoding practices (e.g., phonological awareness, phonics, and reading fluency) and when their special education teacher graduated from a teacher education program that also emphasized these practices. Students with high-incidence disabilities in districts that emphasized balanced literacy practices tended to have lower reading gains. Finally, students with high-incidence disabilities taught by early-career special education teachers tended to have larger reading gains when their teacher’s student teaching placement was supervised by a more experienced cooperating teacher.

Full Abstract
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 candidates (over 80%), but we document considerably lower rates of entry into special education classrooms for candidates who hold a dual endorsement in special education and another subject. We also find that special education teachers who are dual endorsed and begin their careers teaching in special education classrooms are less likely stay in these classrooms. Both sets of findings are supported by an instrumental variable analysis that exploits passing score cutoffs on required licensure tests to provide plausibly causal evidence that obtaining a dual endorsement significantly reduces the likelihood that special education candidates teach in special education classrooms.

Full Abstract
While the majority of students with disabilities (SWDs) receive instruction from general education teachers, little empirical work has investigated the ways in which these students have equitable access to high-quality teachers. We explore the differences in teacher quality experienced by SWDs and general education (GEN) students and how that access varies with school-level disadvantage by estimating SWD teacher quality gaps in the Los Angeles Unified School District. We examine several different indicators of teacher effectiveness (hiring scores, teacher experience, teachers’ ratings on their observation-based performance evaluations, and value-added measures) for general education teachers who instruct both SWDs and general education (GEN) students. We find that SWDs are significantly more likely to have lower math VAM teachers than their GEN peers, and these gaps do not vary by school-level disadvantage. We find no differences on the other indicators of teacher effectiveness.

Full Abstract
We use longitudinal data on high school students in Washington State to assess the relationships between English Language Arts (ELA) teacher value added and other qualifications and the high school and postsecondary outcomes of their students. We also investigate whether these relationships differ for students with and without disabilities. We find that students assigned to 10th grade ELA teachers with higher value added have better test scores, are more likely to graduate on-time, and are more likely to attend and graduate from a four-year college than observably similar students assigned to 10th grade ELA teachers with lower value added. We also find that many of these relationships vary for students with and without disabilities, as 10th grade ELA teacher value added is more positively predictive of on-time graduation and four-year college attendance for students without disabilities, but more positively predictive of two-year college attendance and employment within two years of graduation for students with disabilities. In contrast to value added, other teacher characteristics like experience, degree level, endorsement area, and licensure test scores do not consistently predict better outcomes for students with or without disabilities.

Full Abstract
We use longitudinal data on all high school students in Washington State, including postsecondary education and workforce outcomes, to investigate predictors of intermediate and postsecondary outcomes for students with disabilities. We pay particular attention to career and technical education (CTE) enrollment and the extent of inclusion in general education classrooms, as prior research suggests these factors may be particularly important in influencing the outcomes of students with disabilities. We estimate models that compare students with other students within the same school district, who are receiving special education services for the same disability, and have similar baseline measures of academic performance and other demographic information. We find generally weak relationships between CTE enrollment in any particular grade and intermediate and postsecondary outcomes for students with disabilities, though we replicate earlier findings that students with disabilities who are enrolled in a “concentration” of CTE courses have higher rates of employment after graduation than students with disabilities who are similar in other observable ways but are enrolled in fewer CTE courses. We also find consistently strong evidence that students with disabilities who spend more time in general education classrooms experience better outcomes—fewer absences, higher academic performance, higher rates of grade progression and on-time graduation, and higher rates of college attendance and employment—than students with disabilities who are similar in other observable ways but spend less time in general education classrooms.

This study examines the community-wide effects of investments in two early childhood initiatives in North Carolina (Smart Start and More at Four) on the likelihood of a student being placed into special education. We take advantage of variation across North Carolina counties and years in the timing of the introduction and funding levels of the two programs to identify their effects on third-grade outcomes. We find that both programs significantly reduce the likelihood of special education placement in the third grade, resulting in considerable cost savings to the state. The effects of the two programs differ across categories of disability, but do not vary significantly across subgroups of children identified by race, ethnicity, and maternal education levels.

Full Abstract
This paper contributes importantly to the growing literature on the training of special education teachers and how it translates into classroom practice and student achievement. The authors examine the impact of pre-service preparation and in-service formal and informal training on the ability of teachers to promote academic achievement among students with disabilities. Using student-level longitudinal data from Florida over a five-year span the authors estimate “value-added” models of student achievement. There is little support for the efficacy of in-service professional development courses focusing on special education. However, teachers with advanced degrees are more effective in boosting the math achievement of students with disabilities than are those with only a baccalaureate degree. Also pre-service preparation in special education has statistically significant and quantitatively substantial effects on the ability of teachers of special education courses to promote gains in achievement for students with disabilities, especially in reading. Certification in special education, an undergraduate major in special education, and the amount of special education coursework in college are all positively correlated with the performance of teachers in special education reading courses.

Full Abstract
Mounting pressure in the policy arena to improve teacher productivity either by improving signals that predict teacher performance or through creating incentive contracts based on performance—has spurred two related questions: Are there important determinants of teacher productivity that are not captured by teacher credentials but that can be measured by subjective assessments? And would evaluating teachers based on a combination of subjective assessments and student outcomes more accurately gauge teacher performance than student test scores alone? Using data from a midsize Florida school district, this paper explores both questions by calculating teachers' "value added" and comparing those outcomes with subjective ratings of teachers by school principals. Teacher value-added and principals' subjective ratings are positively correlated and principals' evaluations are better predictors of a teacher's value added than traditional approaches to teacher compensation focused on experience and formal education. In settings where schools are judged on student test scores, teachers' ability to raise those scores is important to principals, as reflected in their subjective teacher ratings. Also, teachers' subject knowledge, teaching skill, and intelligence are most closely associated with both the overall subjective teacher ratings and the teacher value added. Finally, while past teacher value added predicts future teacher value added the principals' subjective ratings can provide additional information and substantially increase predictive power.
