Autism Assessment (ADOS)

The Autism Diagnostic Observation Schedule Second Edition (ADOS-2) is a semi-structured tool. This observation-based assessment typically takes 45 minutes to 1 hour. 

The ADOS-2 assesses current social skills and particular interests and behaviours. 

For children, it primarily includes play-based activities. For adolescents and adults, it is structured as a discussion between the clinician and the individual on a range of topics. 

Four different modules make up the ADOS: 

  1. Module One – non-verbal scenarios are used for scoring 
  2. Module Two – designed for kids who have minimal verbal communication skills and involves moving around the room and interacting with objects. 
  3. Module Three – designed for kids who are verbally fluent and done at a desk or table. 
  4. Module Four – designed for young people who are verbally fluent but beyond the age of playing with toys. This involves a more conversational aspect. 

Our reception staff may ask questions about your child’s language skills to help the therapist determine which module is best suited. Each of the modules consists of a set of standardized scenarios. 

We understand that this is an important appointment for you and your child. It’s normal to feel anxious, because you want to do the best for your child. The ADOS is not a judgment, nor does it have right/ wrong answers. This process captures your child’s skills at one point-in-time, and as a standardized clinical tool, it could never capture their joys, difficulties and unique personality. It is one piece of the puzzle. 

The ADOS does not diagnose, however helps form a picture for your child’s treating doctor. 


What is the process? 

  1. A young person is referred to the ADOS clinician for an assessment, as there may be information required for a diagnosis. 
  2. The assessment time is booked with reception, as well as a feedback session.
  3. Session duration is 45-60 minutes. 
  4. The clinician scores and writes the report. 
  5. A feedback session with the parent/carer takes place, at least 2 weeks after the ADOS. This can take place in-clinic, or via telehealth. 
  6. The report is forwarded to the child’s doctor and therapists (with your permission), who use the ADOS report to help form a whole picture, and to form a diagnosis. 

Some more information on the ADOS can be found here.

The above link includes a video for older children to explain the ADOS process. 



The cost of the assessment is $969.80*, paid in two instalments: 

  • prior to the first assessment session 
  • at the parent feedback session when the report will be given and discussed. 

 * pricing as at August 2023

Usually NDIS funds are not applicable for assessments to access the scheme. Existing NDIS participants should talk to their planner about use of NDIS funds for this service. 

A medicare rebate may be applicable with Medicare item 82010 which requires a Medical referral (GP, Paediatrician or Psychiatrist). 



Our usual cancellation fees apply ($193.96/hour) where a clear 24 hour period of time is not given prior to a cancellation for any reason. We still have to pay our staff, rent and account for the time already invested in the booking process.
