Comparing Estimates of Teacher Value-Added Based on Criterion- and Norm-Referenced Tests - Researchers compared estimates of teacher value-added based on two assessments, the criterion-based Indiana Statewide Testing for Educational Progress Plus and the norm-referenced Measures of Academic Progress. Findings indicated some variability between the estimates of teacher value-added from the two tests; they were moderately correlated. Incorporating confidence intervals for value-added estimates reduces the likelihood that teachers' performance will be misclassified based on measurement error.
