At Georgetown Psychology Associates, we provide Autism Spectrum evaluations ranging from young children to adults. As part of the evaluation process, we administer the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2). For some clients and families, they previously have not heard of the ADOS-2 prior to coming to our office. As such, we have pulled together some key information regarding the ADOS-2 and what to expect from the assessment.

  • The ADOS-2 is a standardized, semi-structured, observational measure utilized in both clinical and research settings.
  • It consists of five modules, which vary based on the age and language level of the individual being evaluated.
  • Clients are administered only one module of the ADOS-2 at the time of testing. The assessment examines an individual’s communication, social interaction skills, play, and restricted and repetitive behaviors.
  • The ADOS-2 is designed for use with children as young as 12 months ranging up to adults.
  • Importantly, the ADOS-2 is often thought of as a “gold standard” in the diagnosis of Autism Spectrum Disorder across stages of development.

Administration of the ADOS-2 typically takes approximately one hour. For young children, parents are allowed to stay with the child during the testing session. Depending on the module administered, tasks typically involve play- and interview-based activities. After the testing is completed, parents or adults return to the office for a feedback session when findings, diagnostic impressions, and recommendations are reviewed. All of this information also is written up in a formal report.
