About ADOS-2 Testing
The Autism Diagnostic Observation Schedule, Second Edition (ADOS-2 — the gold-standard instrument for autism assessment) is the most widely used and validated instrument for assessing autism spectrum disorder. At CPS, our psychologists are trained in ADOS-2 administration and scoring. This page is for parents of young children or adults who suspect they (or their child) may be on the autism spectrum.
The ADOS-2 uses structured and semi-structured activities to observe communication, social interaction, play, and restricted/repetitive behaviors. Different modules are available for toddlers through adults, including a module specifically for verbally fluent adolescents and adults. For patients needing additional support beyond the assessment process, CPS offers an Intensive Outpatient Program (IOP — a structured treatment program involving several hours of therapy per week).
An ADOS-2 evaluation at CPS is part of a comprehensive autism assessment that includes developmental history, cognitive testing, adaptive behavior measures, and clinical observation.
