The Special Education Teacher Pipeline: Teacher Preparation, Workforce Entry, and Retention

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.
