Wang, Chun; Chang, Hua-Hua; Boughton, Keith A. – Applied Psychological Measurement, 2013
Multidimensional computerized adaptive testing (MCAT) is able to provide a vector of ability estimates for each examinee, which could be used to provide a more informative profile of an examinee's performance. The current literature on MCAT focuses on the fixed-length tests, which can generate less accurate results for those examinees whose…

Leung, Chi-Keung; Chang, Hua-Hua; Hau, Kit-Tai – Applied Psychological Measurement, 2002
Item exposure control, test-overlap minimization, and the efficient use of item pool are some of the important issues in computerized adaptive testing (CAT) designs. The overexposure of some items and high test-overlap rate may cause both item and test security problems. Previously these problems associated with the maximum information (Max-I)…
