A computer-adaptive test (CAT) is a responsive test designed to adjust the level of difficulty of the questions based on the test taker’s performance. Computer-adaptive tests are considered to be on the leading edge of testing technology. Computer-adaptive tests are able to assess a student’s abilities more precisely, and often with a fewer number of questions.  During the test, when you answer a question correctly, the computer will follow up with a more difficult question. Likewise, if you miss a question then the computer will present you with an easier question. The algorithm that determine the level of difficulty continues this process throughout the exam to determine the test taker’s understanding of the subject.  Scoring of a CAT is determined based on both the number of correct answers and the difficulty level of those questions. Therefore a raw score of the number of questions answered correctly would not be meaningful or useful information.
