Peer reviewedHalkitis, Perry N. – Journal of Outcome Measurement, 1998
The precision of a computerized adaptive test (CAT) with a limited item pool was measured using test results from 4,494 nursing students. Regardless of the item pool size, CAT provides greater precision in measurement with a smaller number of items administered even when the choice of items is limited, but CAT fails to achieve equiprecision along…

According to item response theory (IRT), examinee ability estimation is independent of the particular set of test items administered from a calibrated pool. Although the most popular application of this feature of IRT is computerized adaptive (CA) testing, a recently proposed alternative is self-adapted (SA) testing, in which examinees choose the…

Lunz, Mary E.; And Others – 1990
This study explores the test-retest consistency of computer adaptive tests of varying lengths. The testing model used was designed as a mastery model to determine whether an examinee's estimated ability level is above or below a pre-established criterion expressed in the metric (logits) of the calibrated item pool scale. The Rasch model was used…
