How CAT Works• Are administered so that results and
responses are recorded electronically• The test taker is given a set of questions that
have been pre-chosen by the test administrator, but as an examinee is taking the test, the test will automatically readjust the next question depending upon the previous response.
Purpose• The main objective of a
CAT test is to match it to the test taker’s true ability level to determine what skills or concepts a students has mastered or would need reinforcement in
