This study was conducted to evaluate a computerized adaptive testing procedure for the measurement of mathematical skills of entry level deaf college students. The theoretical basis of the study was the Rasch model for person measurement. Sixty persons were tested using an Apple II Plus microcomputer. Ability estimates provided by the computerized procedure were compared for stability with those obtained six to eight weeks earlier from conventional (written) testing of the same subject matter. Students' attitudes toward their testing experiences also were measured. Substantial increases in measurement efficiency (by reducing test length) were realized through the adaptive testing procedure. Because the item pool used was not specifically designed for adaptive testing purposes, the psychometric quality of measurements resulting from the different testing methods was approximately equal. Attitudes toward computerized testing were favorable.
