An adaptive testing method is presented that controls the speededness of a test using predictions of the test takers' response times on the candidate items in the pool. Two different types of predictions are investigated: posterior predictions given the actual response times on the items already administered and posterior predictions that use the…

The project reported here consisted of a sensitivity review of the items of Forms 11, 12, and 13 of the Armed Services Vocational Aptitude Battery (ASVAB). Because administration of this battery is a required step in the accession process, it should be free from perceived bias or offensiveness that could detract from the measurement process. In…

A lognormal model for the response times of a person on a set of test items is investigated. The model has a parameter structure analogous to the two-parameter logistic response models in item response theory, with a parameter for the speed of each person as well as parameters for the time intensity and discriminating power of each item. It is…
