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!
1. What Is ADOS-2 Scoring?
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.
- Raw Score: Points tallied from observed behaviors
- Comparison Score: Standardized on a 1–10 scale for cross-module comparison

FAQ
❓ 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.
