“My son’s Module 4 comparison score came back as 6. I finally understood why his eye contact and social chat felt off. My psychologist walked me through each item. Now I know what to ask. I feel equipped to advocate for him at work.”

And here’s a quick infographic for a visual recap:
For local providers, check these directories:
❓ How long does an ADOS-2 assessment take?
Most modules run 30–60 minutes; a full assessment may span 2–3 hours including interview and feedback.
❓ Can a self-report replace ADOS-2?
No—self-screeners (AQ-10, SRS-2) are great first steps but a clinician-led ADOS-2 is required for formal diagnosis and accommodations.
❓ What if my comparison score is borderline?
Ask your clinician for a detailed breakdown of raw subdomain scores and consider a second opinion or complementary measures like the SRS-2.
