An Empirical Comparison of Two-Stage and Pyramidal Adaptive Ability Testing.
Abstract
The administration of ability test items by means of an interactive computer system has enabled test administrators to tailor or adapt tests to individual differences in testee ability. Items are selected by a strategy determined prior to testing, and at one or more points in the testing, a testee's responses are evaluated, and a tentative estimate of ability is made. Subsequent items are generally selected according to the testee's estimated ability. This procedure permits testing time to be shortened without reducing either the reliability or validity of the test. Computerized adaptive testing also has other advantages over conventional tests (see Weiss and Betz, 1973). Comparisons are made with pencil and paper methods.
