ADOS-2: What the Assessment Involves and What to Expect

ADOS-2 is a standardised observational assessment that helps evaluate social interaction, communication, play and behaviour in children and teenagers.

The specialist selects an appropriate module based on the child’s age and language level, conducts the assessment through structured activities and discusses the results with parents. ADOS-2 is part of a comprehensive assessment and is not used as the sole basis for a diagnosis.

Why This Method Matters

Parents often arrive with the question: “Is this autism or not?” ADOS-2 does not answer that with a single word. It provides structured observations: how the child makes contact, how they use speech and gesture, how they play, and how they respond in social situations.

These findings are then considered alongside the developmental history, other methods and the clinical picture. That is why we talk about comprehensive assessment rather than a “test that gives a diagnosis”.

How a Session Usually Goes

• the specialist selects a module based on age and language;
• the child completes tasks and takes part in observational situations;
• results are discussed with parents in clear language;
• recommendations are formed for support, learning and next steps.

What to Keep in Mind

One protocol does not replace clinical judgement. ADOS-2 results cannot be interpreted correctly in isolation from the child’s life context, developmental history and family observations.

If you are considering an assessment, a sensible next step is to briefly describe your request to the centre: age, what is concerning you, and any existing reports. We will help you understand whether ADOS-2 is needed and in what format it is best carried out.
