A long testing window enables the assessment of a test taker’s best performance and at the same time reduces the stress associated with a single sitting test or test offered in a short time window. The longer test window provides the test takers flexibility to take the test when they are best prepared and avoid conflicts with other life events. The test takers will also get the convenience to reschedule the test in case of any exigency. The longer window also provides the test taker with the opportunity to retake the test (maximum 3 attempts, including "No Show") in case they feel that their performance was impaired on the test day for any reason or if they feel they can improve their performance in retake attempt.
