In the 2010 issue of "Teacher Education and Special Education (TESE)," Sindelar and colleagues examined the current status of research on special education teachers and outlined future work necessary to improve the special education teacher workforce. In this article, the authors focus explicitly on Sindelar and colleagues' charge to increase the quality of research on teacher education. They begin the article by conducting a literature review of all articles published in "TESE" from 2010 to 2019, examining papers focused on advancing theory, measurement, and practice in teacher education. They compare patterns in the research to the broader teacher education literature captured in seven special and teacher education journals. They conclude by discussing needs of the field going forward and provide some thoughts about how we might address those needs through a comprehensive research agenda--one that articulates a vision for how we might develop teaching quality at the intersection of general and special education.
