Simple and Effective Algorithms: Computer-Adaptive Testing.
Linacre, John Michael
Computer-adaptive testing (CAT) allows improved security, greater scoring accuracy, shorter testing periods, quicker availability of results, and reduced guessing and other undesirable test behavior. Simple approaches can be applied by the classroom teacher, or other content specialist, who possesses simple computer equipment and elementary programming skills. Building a CAT system involves techniques required for development of an item bank, selection of items, selection of the items and item order to be presented in a test, and evaluating the test for difficulty. A practical understanding of item response theory and pass-fail criteria is helpful. Although CAT tests are usually intended to determine the examinee's ability level, they can supply diagnostic information as well. (TJH)
