About the ADOS-2 Assessment
What is the ADOS-2?
The ADOS-2 is a structured, in-person evaluation used by clinicians to observe how a child communicates, interacts, and responds during guided activities. This assessment gathers detailed information through direct interaction, rather than relying solely on questionnaires or reports. The results help determine whether further diagnostic evaluation for autism spectrum disorder may be recommended.
- Widely used clinical measure
At L.E.M.Y.S, the ADOS-2 is used as part of a comprehensive autism evaluation by trained professionals. Backed by extensive research, it allows clinicians to observe behaviors associated with autism in a consistent and structured way, providing valuable insight for the overall diagnostic process.
- Child-centered interaction
The ADOS-2 is designed to feel natural and engaging for children. Instead of a traditional medical exam, children participate in guided interactions and age-appropriate activities. Sessions at L.E.M.Y.S typically last between 40 and 60 minutes and are structured to help children feel comfortable while clinicians observe key developmental areas.
- Interpreting results
Following the assessment, clinicians score observations based on how a child’s behaviors align with established developmental patterns. A summary of the findings is then shared with the child’s pediatrician or referring provider, who uses this information along with other clinical data to guide diagnosis and next-step recommendations.
What does the ADOS-2 look at?
The ADOS-2 helps specialists understand how your child communicates, plays, and interacts with others. During the session, children take part in guided activities while clinicians observe their behavior in a natural and comfortable setting.
The assessment looks at areas such as:
- How your child makes eye contact and connects with others
- How they play and use their imagination
- How they speak and respond during conversation
- Whether they show repeated movements or very strong interests in specific topics
These observations are scored to help determine whether your child’s behaviors match patterns often seen in children with autism.
How the ADOS-2 modules work
The ADOS-2 includes different modules so the assessment can match your child’s age and language level.
- Toddler Module: For very young children who are just beginning to communicate.
- Module 1: For children who speak in phrases but are still developing conversation skills
- Module 2: For children who speak in phrases but are still developing conversation skills
- Module 3: For children who are able to hold more detailed conversations.
- Module 4: For older teens and adults who are verbally fluent.
At L.E.M.Y.S, the clinical team selects the module that best fits your child’s communication skills and developmental stage to ensure the evaluation is accurate and appropriate.
Understanding the ADOS-2 results
After the ADOS-2 session is completed, clinicians review and score the observations gathered during the evaluation. The results show how a child’s behaviors compare to established developmental patterns associated with autism.
These findings are considered as one part of a comprehensive evaluation. Input from parents or caregivers, developmental history, and clinical expertise are also carefully reviewed to determine whether a diagnosis is appropriate.
