Policymakers and researchers have focused on improving the quality of our nation's 3 million teachers to raise the achievement of students in key academic areas, such as reading and mathematics. Given the importance of teacher quality to student achievement and the key role federal and state governments play in supporting teacher quality, the objectives for this report included examining: (1) the extent that the U.S. Dept. of Education (DoE) funds and coordinates teacher quality programs; (2) studies that DoE conducts on teacher quality and how it provides and coordinates research-related assistance to states and school districts; and (3) challenges to collaboration within states and how DoE helps address those challenges.
