Using Bayesian Decision Theory to Design a Computerized Mastery Test.

Lewis, Charles; Sheehan, Kathleen

Applied Psychological Measurement, v14 n4 p367-86 Dec 1990

A theoretical framework for mastery testing based on item response theory and Bayesian decision theory is described and illustrated. Implementation depends on the availability of (1) a computerized test delivery system; (2) a pool of pretested items; and (3) a model relating observed test performance to true mastery status. (SLD)
