220 students were randomly assigned to a review condition for a medical technology test; their test instructions indicated that each item must be answered when presented, but that the responses could be reviewed and altered at the end of the test. A sample of 492 students did not have the opportunity to review and alter responses. Within the review condition, examinee ability estimates before and after review were correlated .98. The average efficiency of the test was decreased by 1% after review. Approximately 32% of the examinees improved their ability estimates after review but did not change their pass/fail status. Disallowing review on adaptive tests administered under these rules is not supported by these data. (PsycINFO Database Record (c) 2002 APA, all rights reserved).
