Computer adaptive sequential testing
- Computer adaptive sequential testing
Computer-adaptive sequential testing (CAST) is another term for multistage testing. A CAST test is a type of computer-adaptive test or computerized classification test that uses pre-defined groups of items called "testlets" rather than operating at the level of individual items. [Luecht, R.M. (2005). Some useful cost-benefit criteria for evaluating computer-based test delivery models and systems. "Journal of Applied Testing Technology, 7"(2). [http://www.testpublishers.org/Documents/JATT2005_rev_Criteria4CBT_RMLuecht_Apr2005.pdf] ] CAST is a term introduced by psychometricians working for the National Board of Medical Examiners. [Luecht, R. M. & Nungester, R. J. (1998). Some practical examples of computer-adaptive sequential testing. Journal of Educational Measurement, 35, 229-249.] In CAST, the testlets are referred to as "panels".
