Who should undergo a diagnostic assessment of Autism Spectrum Disorder (ASD)
Individuals of any age and functioning level can be assessed if they or their parents are concerned they might be showing signs and symptoms of ASD.

What does a diagnostic assessment involve
A diagnostic assessment involves a detailed parent interview, during which the individual's history of social behavior, language and communication, and interests and behavior are discussed. This is generally followed by an IQ test to determine intellectual strengths and weaknesses. Our licensed psychologist will then administer the ADOS (Autism Diagnostic Observation Schedule), which is a semi-structured evaluation of characteristics of Autism Spectrum Disorder (ASD). Language testing and a school observation may also be conducted as part of the evaluation. Once these steps are completed, our licensed psychologist will meet with you to discuss the results and provide recommendations.

How long does an assessment take
A diagnostic assessment can be completed over the course of 2-3 office visits, each 1-2 hours in duration. For adults, an evaluation can often be completed during one day.

What happens after the assessment is complete
Our licensed psychologist compiles the results into a confidential report. This report can be shared with anyone of the parent s choosing. The report will also include recommendations for treatment.
