Computerized adaptive testing, or CAT, is a form of computer-based test that adapts to the examinee's own ability level, and for this reason has also been called tailored testing. In a computerized adaptive test, the next item or set of items presented to the test taker depends on the correctness of that test taker's responses to the most recently administered items, rather than following a fixed sequence used for every examinee.
