The DDI adaptive reasoning test, also known as ART, is an online psychometric test. This test assesses your ability to reason and learn new information quickly. It has only fifteen questions. You will get several shapes arranged in a definite pattern. Your task is to solve the pattern of the set of shapes in the question. The test is adaptive because the next question's difficulty depends on your performance in the present problem. If you answer the current question wrongly, the next question will be much easier, but if you get the recent question right, the following questions will be more challenging than the previous one. ART can is deployed in assessing all positions in an organization.
