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 responses on these items as an additional source of information. In a simulation study with an adaptive test modeled after a test from the Armed Services Vocational Aptitude Battery, the effectiveness of the methods in removing differential speededness from the test was evaluated.
