In this article, the authors propose an agenda for special education teacher education researchers, with particular attention to policy work and studies of innovations in pre-service preparation, induction and mentoring, and professional development. Because previous research is limited and unfocused, the foundation for future research is weak, but opportunities to study questions of importance and interest are seemingly limitless. The authors discuss strategies to bolster the research foundation, namely, by oversampling special education teachers in the Schools and Staffing Survey and the Teacher Follow-Up Survey and by fostering the development of models of teacher development and related measures of teacher quality.
