Diagnostic evaluations are conducted by a licensed clinical psychologist with expertise in the diagnosis of autism and other pervasive developmental disorders. Evaluation services are available for all ages, from early childhood through adulthood. These are comprehensive evaluations that provide diagnostic information, level of functioning information, and treatment recommendations. Diagnostic evaluations are typically conducted over one- to two-half-day testing sessions depending on client need and referral questions to be answered. Following the evaluation the clinical team will meet with the family to provide a summary of the assessment results along with treatment recommendations.
