Teacher Quality and Student Achievement: A Review of State Policy Evidence


This paper looks at data from all 50 states to examine relationships between teacher qualifications and student achievement. According to Darling-Hammond, "The findings of both the qualitative and quantitative analyses suggest that policy investments in the quality of teachers may be related to improvements in student performance. ... policies adopted by states regarding teacher education, licensing, hiring, and professional development may make an important difference in the qualifications and capacities that teachers bring to their work."
