Teacher Characteristics and Student Achievement Gains: A Review

A large body of studies exists that examines the relationship between student achievement gains and the characteristics of teachers. To help policymakers and researchers use and build on this body of studies, this article reviews the studies systematically and synthesizes their results with deliberate consideration of each study’s qualities. Determinate relationships are described for four categories of teacher characteristics: college ratings, test scores, degrees and coursework, and certification status. The review details the implications of these relationships in light of study limitations and proposes directions for future research.
