q1 i? Computerized adaptive testing adapts by adjusting questions during the testing session rather than administering a fixed item set. → Freeman 2014

The article's abstract, an author explanation rather than a reported study, states that CAT measures "the achievement levels of both low-achieving and high-achieving students by adjusting questions as the testing goes along." No data, sample, or effect size is reported in the available text.

"computerized adaptive testing (CAT). In this article, the authors explain how CAT provides a more precise, accurate picture of the achievement levels of both low-achieving and high-achieving students by adjusting questions as the testing goes along."

Related Claims¶

• Computerized adaptive testing selects test questions based on test takers' answers to previous questions — possibly the same claim (merge candidate)
• Procedures developed for evaluating content alignment of linear tests are not readily applicable to computerized adaptive tests — related
• The study examines how CAT test design and item bank distribution affect content coverage and test efficiency in a CCSS-aligned reading comprehension test — related
• Adaptivity and score reliability of both engines depend on item-pool depth; the CBE often performed better than COLO for extreme low or high achievers when item banks were shallow — related
