Why does it take so long to get my test results since they are computer graded?

The examination committees review each question for validity after the exams are scored. Questions are discarded if they do not meet predefined performance criteria. If statistical evaluation raises a concern about the validity of a question (for example if a large number of people consistently answer with a different response), then these questions are individually reviewed again to make sure they are accurate. When inaccuracies are identified, these questions can be re-scored or discarded. This process does take some time, but it is worth it to get completely valid scores.
