A comparison of item selection rules including precision, content, and exposure considerations at the early stages of computerized adaptive testing
A comparison of item@selection @?rules including precision, content, and @?exposure considerations at the early @?stages of computerized@adaptive@testing (1999) pp. 1–222
It is well known that item selection at the early stages of a computerized adaptive test (CAT) is not as appropriate as it is at the later stages. Several new item selection rules have been proposed to improve early-stage item selection. Based on...

To date, exposure control procedures that are designed to control test overlap in computerized adaptive tests (CATs) are based on the assumption of item sharing between pairs of examinees. However, in practice, examinees may obtain test information...
Applied Psychological Measurement Vol. 29, No. 3 (May 2005) pp. 204–217
This article proposes an item exposure control method, which is the extension of the Sympson and Hetter procedure and can provide item exposure control at both the item and test levels. Item exposure rate and test overlap rate are two indices...
Effects of Practical Constraints on Item Selection Rules at the Early Stages of Computerized Adaptive Testing
Journal of Educational Measurement Vol. 41, No. 2 (June 2004) pp. 149–174
The purpose of this study was to compare the effects of four item selection rules--(1) Fisher information (F), (2) Fisher information with a posterior distribution (FP), (3) Kullback-Leibler information with a posterior distribution (KP), and (4)...
Applied Psychological Measurement Vol. 37, No. 7 (October 2013) pp. 563–582
Interest in developing computerized adaptive testing (CAT) under cognitive diagnosis models (CDMs) has increased recently. CAT algorithms that use a fixed-length termination rule frequently lead to different degrees of measurement precision for...
Applied Psychological Measurement Vol. 24, No. 3 (2000) pp. 241–55
Compared five item selection rules with respect to the efficiency and precision of trait (theta) estimation at the early stages of computerized adaptive testing (CAT). The Fisher interval information, Fisher information with a posterior distribution,...
Comparing Methods of Assessing Differential Item Functioning in a Computerized Adaptive Testing Environment
Journal of Educational Measurement Vol. 43, No. 3 (September 2006) pp. 245–264
Mantel-Haenszel and SIBTEST, which have known difficulty in detecting non-unidirectional differential item functioning (DIF), have been adapted with some success for computerized adaptive testing (CAT). This study adapts logistic regression (LR) and ...
