ADOS-2 (Autism Diagnostic Observation Schedule, Second Edition)

The ADOS-2 (Autism Diagnostic Observation Schedule, Second Edition) is a widely used, standardized assessment tool that helps professionals evaluate whether someone shows signs of autism spectrum disorder (ASD). During the assessment, a trained clinician observes the individual's social interactions, communication skills, play, and behaviors through structured activities and conversations. The goal is to gather consistent, objective information to support an accurate diagnosis. ADOS-2 is considered a reliable and valuable tool in understanding autism, guiding decisions for support and intervention, and providing a clearer picture of an individual’s strengths and challenges related to ASD.
