ADOS-2: What Is It? – Autism Spectrum Evaluations

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.
