Teacher Quality and Educational Equality: Do Teachers with Higher Standards-Based Evaluation Ratings Close Student Achievement Gaps?

Using standards-based evaluation ratings for nearly 400 teachers, and achievement results for over 7,000 students from grades 4-6, this study investigated the distribution and achievement effects of teacher quality in Washoe County, a mid-sized school district serving Reno and Sparks, Nevada. Classrooms with higher concentrations of minority, poor, and low-achieving students were more likely to be taught by teachers with lower evaluation scores. Two-level multilevel models, nesting students within classrooms, tended to show higher mean achievement in classrooms taught by teachers of higher than lower quality, with differences of approximately one-tenth of 1 standard deviation. Findings relating teacher quality to closing within-classroom achievement gaps, though, were mixed. Implications are discussed related to teacher evaluation, teacher quality, and educational inequality.
