Abstract: The present invention relates to computer-based technology in assessment particularly for the licensing and certification of professionals such as architects and engineers. For assessment of architects, the system includes tools and methods for item creation, computer programs for computerized item presentation, and programs for automatically scoring test responses by computer.

Abstract: A computerized mastery testing system providing for the computerized implementation of sequential testing in order to reduce test length without sacrificing mastery classification accuracy. The mastery testing system is based on Item Response Theory and Bayesian Decision Theory which are used to qualify collections of test items, administered as a unit, and determine the decision rules regarding examinee's responses thereto. The test item units are randomly and sequentially presented to the examinee by a computer test administrator. The administrator periodically determines, based on previous responses, whether the examinee may be classified as a nonmaster or master or whether more responses are necessary. If more responses are necessary it will present as many additional test item units as required for classification.
