Student achievement test scores were compared and equated, using three different testing methods: paper-administered, computer-administered, and computerized adaptive testing. The tests were developed from third and sixth grade mathematics item banks of the California Assessment Program. The paper and the computer-administered tests were identical…

The advantages of computerized adaptive testing are discussed, and an example illustrates its use in sixth grade mathematics. These tests are administered at a computer terminal, and the test items to be administered are selected according to the difficulty level appropriate to the individual's ability. Tailoring increases the psychometric…

A new testing strategy that provides protection against the problem of having examinees in adaptive testing choose difficulty levels that are not matched to their proficiency levels was introduced and evaluated. The method, termed restricted self-adapted testing (RSAT), still provides examinees with a degree of control over the difficulty levels…

In this study, 590 third graders from 12 Dutch schools took 32 tests indicating 16 semantic Structure-of-Intellect (SI) abilities and 1 of 4 reading comprehension tests, involving either multiple-choice or open-ended items. Results indicate that item type for reading comprehension is congeneric with respect to SI abilities measured. (TJH)
