In computerized adaptive testing, item exposure control methods are often used to provide a more balanced usage of the item pool. Many of the most popular methods, including the restricted method (Revuelta and Ponsoda), use a single maximum exposure rate to limit the proportion of times that each item is administered. However, Barrada et al.…

Research has found that the "a"-stratified item selection strategy (STR) for computerized adaptive tests (CATs) may lead to insufficient use of high a items at later stages of the tests and thus to reduced measurement precision. A refined approach, unequal item selection across strata (USTR), effectively improves test precision over the…

The International Test Commission's "Guidelines for Translating and Adapting Tests" (2010) provide important guidance on developing and evaluating tests for use across languages. These guidelines are widely applauded, but the degree to which they are followed in practice is unknown. The objective of this study was to perform a…

A pilot study of a computerized adaptive test of mathematics achievement was conducted in May and June 1989 in selected schools of the San Diego Unified School District. The study evaluated the usefulness of the test for determining eligibility for Chapter 1 programs in mathematics. The test was a prototype battery of three adaptive tests: (1)…

Three test administration procedures for making placement decisions in adult education were compared (paper-based, computer-based, and computerized-adaptive tests) with 90 adult-education students. Test performance was not differentially affected by the mode of administration, but the computerized adaptive test always yielded more precise ability…

Efficiency, precision, and concurrent validity of results from adaptive and fixed-item music listening tests were studied using: (1) 2,200 simulated examinees; (2) 204 live examinees; and (3) 172 live examinees. Results support the usefulness of adaptive tests for measuring skills that require aurally produced items. (SLD)

Vocabulary fixed-item (FIT), computerized-adaptive (CAT), and self-adapted (SAT) tests were compared with 121 college students. CAT was more precise and efficient than SAT, which was more precise and efficient than FIT. SAT also yielded higher ability estimates for individuals with lower verbal self-concepts. (SLD)

Thousands of older incarcerated youth (17-18 years old) pass through the juvenile justice system every year. Many are not viable candidates for traditional high school graduation because of limited earned credits and large gaps in education. The purpose of this study was to establish an effective and efficient means for determining students'…

The Grammar, Spelling, and Punctuation (GSP) test is administered to students in the College of Communication at the University of Texas, Austin, as a means of determining eligibility to register for certain courses in journalism, broadcasting, and advertising. The test was administered in a paper-and-pencil version to 16 students and in a…

Concepts of adaptive testing and the related measurement model, item response theory, are introduced and benefits and limitations are outlined. Field tests with over 2,500 students illustrate the use of adaptive tests in college placement. Some future directions for computerized adaptive testing are considered. (SLD)

A mail survey about the use of instruments in 9 assessment areas was answered by 389 school psychologists. Comparison with a similar survey 10 years earlier suggests no decline in assessment overall, although emphasis is switching away from intelligence testing, toward achievement testing, behavior rating, and adaptive measurements. (SLD)

Eighth grade teachers in three local school districts helped customize two standardized norm-referenced tests for ninth graders to investigate effects of deleting some items and adding locally constructed items. Results indicate that percentile ranks for the customized tests could be very different from those for the complete test. (SLD)

This study examined performance of a simulated computerized adaptive test that was designed to help direct the development of a medical recertification examination. The item pool consisted of 229 single-best-answer items from a random sample of 3,000 examinees, calibrated using the two-parameter logistic model. Examinees' responses were known. For…
