A method is presented for incorporating a large number of constraints on adaptive item selection in the construction of computerized adaptive tests. The method, which emulates practices of expert test specialists, is illustrated for verbal and quantitative measures. Its foundation is application of a weighted deviations model and algorithm. (SLD)

A factor analysis was used to study the relationships among response time and accuracy scores for a verbal analogies test, as well as a number of experimental variables designed to measure a series of information processing stages of the analogies task. (CTM)

The effects of providing immediate feedback on an item-by-item basis to testees were investigated on several samples of undergraduates who were administered either adaptive or conventional tests. Results generally indicated that knowledge of results improved test performance. (JKS)

This research investigated the use of the Rasch simple logistic model in obtaining test-free ability estimates. Raw-score ability estimates were influenced by the difficulty of the items used in measurement but Rasch ability estimates were relatively independent of the item difficulty. (Author/CTM)

Two sets of mathematical reasoning and two sets of verbal comprehension items were cast into each of three formats--constructed response, standard multiple-choice, and Coombs multiple-choice--in order to assess whether tests with identical content but different formats measure the same attribute. (Author/CTM)

The scope and nature of sex differences in the Graduate Record Examination are explored by identifying individual test items that differ from the other items in terms of the magnitude of the difference in item difficulty for the sexes. In general, limited evidence of differences was established. (Author/CTM)

Mokken models of monotone homogeneity and double monotonicity and the Rasch model are compared using data from 990 young adult examinees taking a Dutch verbal intelligence test--the Verbal Analogies Test. The model of monotone homogeneity was found suitable for basic testing; more sophisticated applications appear to require parametric models.…

This study investigated the adequacy of the Rasch model in equating existing standardized tests with groups of examinees not widely separated in ability. With the exception of one test pair and one grade level, the Rasch model using the anchor test procedure provided a reasonably satisfactory means of equating. (Author/CTM)

This research attempted to interrelate several methods of producing option weights (i.e., Guttman internal and external weights and judges' weights) and examined their effects on reliability and on concurrent, predictive, and face validity. It was concluded that option weighting offered limited, if any, improvement over unit weighting. (Author/CTM)

Undergraduate students were administered one of three conventional or one of three stratified adaptive vocabulary tests with or without knowledge of results. Results indicated that knowledge of results and test difficulty affected performance. (Author/JKS)
