How to compare autism assessment clinics

An autism assessment or diagnostic evaluation can involve interviews, questionnaires, developmental history, and structured observation. The exact assessment process varies by clinic and by whether the patient is a child, youth, or adult. Ask what is included before joining a waitlist or paying a deposit.

  • Do you assess adults in my age group and with my communication or accessibility needs?
  • Is a physician referral required, and what are the current eligibility criteria?
  • Which regulated professional is responsible for the diagnosis and final report?
  • What records or informant interviews are requested, and what happens if childhood records are unavailable?
  • What is included in the quoted fee, and are feedback sessions or forms charged separately?
  • What is the current wait for intake and for the completed report?
  • Will the report include practical recommendations for accommodations and next steps?

Referral and diagnostic assessment pathways

Public diagnostic hubs and hospital services may require a referral form and apply their own eligibility rules. Private clinics may use direct intake, but families should still confirm who makes the diagnosis, which records are needed, what the written report includes, and whether the documentation fits the Ontario Autism Program or another service they plan to access.
