If you’re navigating an autism assessment, ADOS-2 scores can feel like alphabet soup. This guide walks you through each module. It shows real-parent examples. Additionally, it embeds a quick video and infographic to make sense of everything. Let’s dive in!
The Autism Diagnostic Observation Schedule, Second Edition (ADOS-2), is a gold-standard observational tool. Clinicians use it to assess communication, social interaction, and play.
For more on adult testing pathways, see our Adult Autism Diagnosis Guide.

“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.”
— Jessica, parent & autism advocate
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.
