Most of the exams are presented in an adaptive test format. Adaptive testing gives a more accurate assessment of the test taker s knowledge. Experts claim that traditional multiple-choice tests often present too many questions and do not accurately measure the student s ability to answer difficult questions.
Adaptive testing adjusts itself to the test taker s level of knowledge.
It discovers the level, on a scale of easy to difficult, at which the person begins to encounter challenging questions. A score is derived for that level. The test first presents a question of medium difficulty. After the answer is given, it is scored immediately. If correct, the test statistically estimates the persons ability as higher than previously estimated.
