Definition
The ADOS, or Autism Diagnostic Observation Schedule, is a structured assessment a trained professional uses to observe how a child or adult communicates, plays, and interacts. Through a series of activities and prompts, the clinician notes patterns that inform an autism evaluation. It is one tool among several, not a standalone verdict.
Why It Matters
The ADOS is a common part of a full autism assessment, so parents often encounter it during the diagnostic process. Understanding that it captures behavior in one setting on one day helps families see it as a snapshot rather than a complete picture of their child.
Common Misconception
Some believe the ADOS alone diagnoses autism, but qualified clinicians weigh it alongside developmental history, parent input, and other information. A quiet or unusual session does not automatically confirm or rule out autism.
