Computerized adaptive testing (CAT) and multistage testing (MST) have become two of the most popular modes in large-scale computer-based sequential testing. Though most designs of CAT and MST exhibit strength and weakness in recent large-scale implementations, there is no simple answer to the question of which design is better because different…

Discusses the future of computerized adaptive testing (CAT), i.e., experimental tests developed by the Educational Testing Service in response to criticism of the Standardized Aptitude Tests (SATs). CAT examinations are individually tailored to each test taker, and researchers believe they are more predictive than conventional SATs. (JJD)
