Estimating the Consistency and Accuracy of Classifications Based on Test Scores.

Livingston, Samuel A.; Lewis, Charles

Journal of Educational Measurement, v32 n2 p179-97 Sum 1995

A method is presented for estimating the accuracy and consistency of classifications based on test scores. The reliability of the score is used to estimate effective test length in terms of discrete items. The true-score distribution is estimated by fitting a four-parameter beta model. (SLD)
