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)

Describes the rationale underlying computerized adaptive testing (CAT), discusses the psychometric and technical developments which make it practical, and reviews some previous work which has shaped the current state of the art. The possible advantages, constraints, and operational requirements, and possible areas of application are examined.…

A conventional vocabulary test and two forms of a stradaptive vocabulary test were administered by a time-shared computer system to undergraduate college students. The two stradaptive tests differed in that one counted question mark responses (i.e., omitted items) as incorrect and the other ignored items responded to with question marks.…

This study empirically investigated the validity and utility of the stratified adaptive computerized testing model (stradaptive]developed by Weiss (1973). The model presents a tailored testing strategy based on Binet IQ measurement theory and Lord's (1972) modern test theory. Nationally normed School and College Ability Test Verbal analogy items…

The concept of tailored testing for individuals is applied to the construction of tests for special groups and extended to apply to item content as well as item difficulty. It is suggested that evaluators may decide to construct tests on the basis of a unique combination of items drawn from an item bank to fit the need of a particular group. At…

The research from a four-year project of implied orders tailored testing is summarized. The method of implied orders testing combines the principles of ordinal measurement with the concept of the Guttman scale as an ideal. The basic principle for dichotomous items is that either an item is missed and "dominates" a person or it is answered…

Latent trait model calibration procedures were used on data obtained from a group testing program. The one-parameter model of Wright and Panchapakesan and the three-parameter logistic model of Wingersky, Wood, and Lord were selected for comparison. These models and their corresponding estimation procedures were compared, using actual and simulated…

This report contains 11 tables and 5 figures documenting the results for the General Educational Development (GED) tests in 1992. The tables provide information on the following: testing volumes; percent tested by age group; credentials issued by age group; testing by language; testing by special editions and adaptations; highest grade completed;…

This report contains 13 tables and 13 figures documenting the results for the General Educational Development (GED) tests in 1994. The tables and figures provide information on the following: GED participation and credentials issued--percent change from 1993 to 1994; testing volumes; percent tested by age group; credentials issued by age group;…
