Students exhibit many behaviors when responding to items on a computer-based test, but only some of these behaviors are relevant to estimating their proficiencies. In this study, we analyzed data from computer-based math achievement tests administered to elementary school students in grades 3 (ages 8-9) and 4 (ages 9-10). We investigated students'…

Evaluated the structural equivalence and differential item functioning of an employee attitude survey from a large international corporation across three languages, eight cultures, and two mediums of administration. Results for 40,595 employees show the structure of survey data was consistent and items functioned similarly across all groups. (SLD)

Evaluating the comparability of a test administered in different languages is a difficult, if not impossible, task. Comparisons are problematic because observed differences in test performance between groups who take different language versions of a test could be due to a difference in difficulty between the tests, to cultural differences in test…

Achievement testing in the next century is going to be very different. Computer technology is going to play a major role in test construction, test administration, scoring, and score reporting. New formats will become possible that incorporate visual and audio components and that permit adaption of tests to individual ability levels. (SLD)
