What Is Computer Adaptive Testing?

Computer adaptive testing is a new form of testing that varies the difficulty, level, and order of questions that get asked depending on your performance within the test. This is in contrast to static testing, where the questions are predefined and nothing changes during the exam.

The GRE and GMAT are examples of computerized adaptive tests designed using IRT principles, wherein the choice and difficulty of each subsequent question is in part determined by performance on the previous questions. The number and application of IRT models continues to expand.
