In many testing programs it is assumed that the context or position in which an item is administered does not have a differential effect on examinee responses to the item. Violations of this assumption may bias item response theory estimates of item and person parameters. This study examines the potentially biasing effects of item position. A…

The aim of this research was to identify, develop, and evaluate empirically new reasoning item types that might be used to broaden the analytical measure of the Graduate Record Examinations (GRE) General Test and to strengthen its construct validity. Six item types were selected for empirical evaluation, including the two currently used in the GRE…

A previous study of new item types for the analytical measure of the Graduate Record Examinations (GRE) General Test found that the new items had many factors labeled verbal reasoning, informal reasoning, formal-deductive reasoning, and quantitative reasoning. The present study examined how processing differed for these item types in the context…

The stability was evaluated of a partial correlation index, comparisons of item characteristic curves, and comparisions of item difficulties in assessing race and sex differences in the performance of verbal items on the Graduate Record Examination Aptitude Test. All three indexes exhibited consistency in identifying the same items in different…

Time limits on tests often prevent some examinees from finishing all of the items on the test; the extent of this effect has been called the "speededness" of the test. Traditional speededness indices focus on the number of unreached items. Other examinees in the same situation rapidly fill in answers in the hope of getting some of the…
