The diagnostic process will consist of a multidisciplinary assessment procedure that includes a review of medical records, detailed developmental history, description of current behaviors, assessment of cognitive/language abilities and observations of functioning in a variety of settings (American Psychiatric Association, 2004). Upon completion of the evaluation, a comprehensive psychological report is developed which includes a diagnosis and treatment recommendations.
