Autism Spectrum Disorder Diagnostic Hubs

Evidence shows that when children start behavioural intervention between ages two and five, they gain improvements in cognitive and language development, are better prepared for school and have better long-term outcomes in adulthood.

Frequently Asked Questions

How can I get an autism assessment for my child?

Please contact your local hub through one of the links below to find out about how to apply for a diagnostic assessment.

Do I have to go through the diagnostic hubs to have my child assessed for an autism diagnosis?

No, you can receive a diagnosis of autism from qualified professionals, including family physicians, pediatricians and developmental pediatricians, psychiatrists, psychologists, psychological associates, and nurse practitioners.

How will my child be assessed for signs of autism?

Autism is diagnosed based on a combination of specific behaviours, communication delays, and/or developmental disabilities, rather than only one factor or symptom. Diagnosing professionals use the fifth edition of the Diagnostic and Statistics Manual of Mental Disorders (DSM-5) to conduct the assessment.

The multi-disciplinary diagnostic assessment process in the diagnostic hubs includes:

  • a semi-structured interview, informal observation of your child, and a review of other documents and reports, as well as previous assessments, including information from a school or child care provider
  • the administration of a standardized assessment tool such as the Autism Diagnostic Observation Schedule and a review of diagnostic criteria outlined in the DSM 5

Following the assessment, you will receive a report that summarizes the assessment results and the diagnosis. It also provides information about potential next steps. Post-diagnosis, the hubs will connect you with other appropriate services and supports in your community.
