Autism Spectrum Disorder Diagnostic Assessment

Holland Center offers a comprehensive diagnostic assessment for suspected autism spectrum disorders.

Overview of the Diagnostic Assessment Process:
Our staff psychologist administers a series of parent questionnaires, including the Autism Diagnostic Interview, conducts formal cognitive testing with the child, and performs the Autism Diagnostic Observation Schedule (ADOS) with the child.  Our speech and language pathologist will conduct formal language testing, and a comprehensive and diagnostic report will be written and provided to you upon feedback of the evaluation. 

The assessment is conducted across 2 separate days during the same week, typically on Monday and Wednesday from 9am – 12pm. The following outline is a breakdown of what your evaluation days will look like:
