We investigate two research questions using a recent statewide transition from paper to computer-based testing: first, the extent to which test mode effects found in prior studies can be eliminated; and second, the degree to which online and paper assessments offer different information about underlying student ability. We first find very small…

Computer-based, pop-up glossaries are perhaps the most promising accommodation aimed at mitigating the influence of linguistic structure and cultural bias on the performance of English Learner (EL) students on statewide assessments. To date, there is no established procedure for identifying the words that require a glossary for EL students that is…

Many innovative item formats have been proposed over the past decade, but little empirical research has been conducted on their measurement properties. This study examines the reliability, efficiency, and construct validity of two innovative item formats--the figural response (FR) and constructed response (CR) formats used in a K-12 computerized…

Moreover, the quality of computer-based test administration systems…
