This paper addresses likely error rates for measuring teacher and school performance in the upper elementary grades using value-added models applied to student test score gain data. Using realistic performance measurement system schemes based on hypothesis testing, we develop error rate formulas based on OLS and Empirical Bayes estimators.…

Setting a cutting score is a key problem in criterion-referenced measurement which is discussed within a decision theoretic approach when just one student is considered. A minimum information solution is given and compared with approaches when there is information about a group of students. Formulas illustrate the discussion. (CM)
