Demystifying the Clinic Room: What Actually Happens During Your Activity-Based Assessment (ADOS-2)?
When you or your child are preparing for an autism assessment, the unknown can feel overwhelming. A common question we receive from families and individuals is: “What is actually going to happen when we step into the clinic room?”
To help put your mind at ease, we want to break down what you can expect during the observational part of the assessment—commonly referred to in clinical terms as the ADOS-2, or what we simply call your Activity-Based Assessment.
What is an Activity-Based Assessment (ADOS-2)?
The Activity-Based Assessment (ADOS-2) is a standardised, observational session conducted directly with the individual (whether a child, young person, or adult).
Rather than feeling like a formal test or exam, the session uses structured activities, light conversations, and interactive scenarios. This creates a comfortable space for our clinicians to observe natural social interaction, communication styles, play, and repetitive behaviors in real time.
What Can You Expect During the Session?
The structure of the session is adapted depending on age, language skills, and developmental level, but generally, here is what the environment and activities look like:
Interactive Tasks & Play: Depending on age, the session may involve playing with specific toys, looking at picture books, telling a story, or working through creative problem-solving activities together.
Open Conversation: For older children, teens, and adults, the session feels more like a relaxed, guided conversation covering everyday topics like interests, social experiences, emotions, and daily routines.
By keeping the environment supportive and low-pressure, our goal is simply to get to know you or your child and observe how you naturally interact and navigate different tasks.
Why Don't We Share Every Detail in Advance?
It’s completely natural to want to know every single step before arriving, and many people feel tempted to search online or look up task descriptions on social media. However, we intentionally keep the specific activities lighthearted and surprising!
The true value of an Activity-Based Assessment comes from spontaneous, authentic reactions. When someone knows the exact tasks beforehand, they can end up feeling self-conscious or overthinking their responses, which can make the experience more stressful. Rest assured, there are no "right" or "wrong" answers, and no preparation or studying is required - you just need to show up as yourself.
Next Steps
The Activity-Based Assessment is just one piece of our comprehensive, multi-disciplinary evaluation process. Combined with our clinical interviews informed by standardized measures, it helps us build an accurate, holistic picture of your or your child's unique strengths and needs.
