Within a few years the Department of Defense may begin administering the Armed Services Vocational Aptitude Battery ASVAB using computerized adaptive testing CAT. In CAT, each test item is characterized by an item response curve IRC, which describes how the probability of correctly answering the item increases with ability. A recent study conducted by the Center for Naval Analyses found that IRCs of many items in the experimental CAT item pool for the ASVAB changed substantially from paper-pencil to CAT administration. This research memorandum examines the effects of these changes on scores of individual examinees. Keywords Bayes Theorem calibration Chi Square Test Estimates Mathematical analysis Test Methods.
