Some Procedures for Computerized Ability Testing. Project Psychometric Aspects of Item Banking No. 13. Research Report 86-10.
van der Linden, Wim J.; Zwarts, Michel A.
The use of item response theory (IRT) is a prerequisite to successful use of computerized test systems. In item response models, as opposed to classical test theory, the abilities of the examinees and the properties of the items are parameterized separately. Therefore, when measuring the abilities of examinees, the model implicitly corrects for the item properties, and measurement on an item-independent scale is possible. In addition, IRT offers the use of test and item information as local reliability indices defined on the ability scale. The application of IRT in procedures for computerized testing is discussed for: (1) calibrating item banks; (2) automated test construction; (3) adaptive test administration; (4) generating norm distributions; and (5) diagnosing test scores. A 49-item list of references is included. Three figures and one table illustrate the application of IRT to computerized testing. (SDL)
