Report analyzes accuracy of classifying performance of teachers, schools

A new technical methods report released July 26 analyzes error rates in measuring teacher and school performance based on measures of student test score gains. The report, Error Rates in Measuring Teacher and School Performance Based on Student Test Score Gains was released by the National Center for Education Evaluation and Regional Assistance. The report examines the accuracy with which teachers and schools may be classified as low or high performers.

The purpose of the study is to advance understanding of error rates associated with performance measurement systems currently in use, and to provide input into the design of alternative strategies. Among the findings, results suggest there needs to be careful consideration of system error rates when only several years of data are used for analysis.
