In recent years, the computerised adaptive test (CAT) has gained popularity over conventional exams in evaluating student capabilities with desired accuracy. However, the key limitation of CAT is that it requires a large pool of pre-calibrated questions. In the absence of such a pre-calibrated question bank, offline exams with uncalibrated…

Develops a conceptual framework that addresses score comparability for performance assessments, adaptive tests, paper-and-pencil tests, and alternate item pools for computerized tests. Outlines testing situation aspects that might threaten score comparability and describes procedures for evaluating the degree of score comparability. Suggests ways…

Computerized adaptive testing (CAT) is described and compared with conventional tests, and its advantages summarized. Some item response theory concepts used in CAT are summarized and illustrated. The author describes the potential usefulness of CAT in counseling and education and reviews some current issues in the implementation of CAT.

Discussion of expert systems and computerized adaptive tests describes two versions of EXSPRT, a new approach that combines uncertain inference in expert systems with sequential probability ratio test (SPRT) stopping rules. Results of two studies comparing EXSPRT to adaptive mastery testing based on item response theory and SPRT approaches are…

Describes a pilot study of computerized adaptive testing in the Michigan Educational Assessment Program's tenth-grade mathematics problem-solving and applications subtests. Comparisons are made to pencil-and-paper tests, and student reactions as determined by a posttest survey are discussed. (LRW)
