The Autism Diagnostic Observation Schedule

The Autism Diagnostic Observation Schedule (ADOS-2) is a semi-structured, standardized assessment of communication, interaction, play, and repetitive and restricted behaviors. The assessment provides information for diagnosing, treatment planning, and educational placement. The ADOS-2 has 5 different modules that serve ages 12 months through adults.

It is a standardized diagnostic screening tool that allows for direct observation in a structured setting that can be replicated by other clinicians.

Most insurances require the ADOS to be a component of the diagnostic process and may require an updated ADOS every year or two  in order to continue supportive services such as ABA.

There are 5 modules that serves individuals 12 months through adulthood. Depending on the age of the child the caregiver(s) may be required to be present during the screening.

The screening will last 40-60 minutes where the clinician will set up various play tasks and ask questions. If the caregiver is present, the clinician will inform him/her when they should participate and/or interject.

After the screening is complete, the clinician will score the assessment and provide a written report of the findings.
