ADOS-2 Module 3

This revision improves an instrument already viewed as “the gold standard” for observational assessment of autism spectrum disorder (ASD).

With updated protocols, revised algorithms, a new Comparison Score, and a Toddler Module, the ADOS-2 provides a highly accurate picture of current symptoms, unaffected by language. It can be used to evaluate almost anyone suspected of having ASD from one year olds with no speech, to adults who are verbally fluent.

Like its predecessor, the ADOS-2 is a semi-structured, standardised assessment of communication, social interaction, play, and restricted and repetitive behaviours.

It presents various activities that elicit behaviours directly related to a diagnosis of ASD. By observing and coding these behaviours, you can obtain information that informs diagnosis, treatment planning, and educational placement.

Because it can be used with a wide range of children and adults, the ADOS-2 is an essential addition to any hospital, clinic or school that serves individuals with developmental disorders.
