Scoring errors and miscalculations are surprisingly common.  Such errors can easily influence the potential interpretation of test scores.  The mischaracterization of test scores is even more common and can often easily be refuted by reference to current peer-reviewed literature.  Evaluators are required to provide their raw data for review to a licensed psychologist.  I regularly review such data for accuracy, currency, completeness, and validity.  I am familiar with almost any test in use for mental health evaluations and possess a large literature concerning the proper administration of tests and the valid interpretation of test scores.
