In this article, I present the results of an analysis of the relationship between teacher evaluation scores and student achievement on district and state tests in reading, mathematics, and science in a large Midwestern U.S. school district. Within a value-added framework, I correlated the difference between predicted and actual student achievement in science, mathematics, and reading for students in Grades 3 through 8 with teacher evaluation ratings. Small to moderate positive correlationships were found for most grades in each subject tested. When these correlationships were combined across grades within subjects, the average correlationships were .27 for science, .32 for reading, and .43 for mathematics. These results show that scores from a rigorous teacher evaluation system can be substantially related to student achievement and provide criterion-related validity evidence for the use of the performance evaluation scores as the basis for a performance-based pay system or other decisions with consequences for teachers.
