ADOS-2 Training for the Clinical Setting

ADOS-2 is a semi-structured, standardized assessment of communication, social interaction, play/imaginative use of materials and restricted and repetitive behaviours for individuals who have been referred because of possible autism spectrum disorder (ASD). Fundamentally new to the ADOS-2 than ADOS-G are the procedures involved in the algorithm computation and the Comparison Score for Module 1 through 3 which were revised on the basis of the findings of recent validation research. The new Comparison Score provides a way of indicating a participant’s level of autism spectrum related symptomatology and it can also be used to interpret an individual’s own change in autism spectrum related symptoms over time. ADOS-2 also includes a Toddler Module, which is designed for very young children who do not use phrase speech but who are between the ages of 12 and 30 months. The Toddler Module has its own algorithms that provide “ranges of concern” instead of cutoff scores. A variety of specialists will use the ADOS-2, their use of results in writing reports and making recommendations to inform medical diagnoses, special education classification and occupational therapists and speech and hearing professionals might use for treatment planning.

Training in the ADOS-2 is now available for use in the clinical setting through the Department of Psychiatry, Trinity College Dublin. The training is aimed at professionals with a mental health background who have some familiarity with the tool and it focused on teaching correct administration of the instrument. This training will take place over two full days. It is highly recommended that attendees should be familiar with the ADOS-2 kit. Kits are available for purchase directly from Western Psychological Services - or through ETC Leeson Park.

The current restrictions and need for social distancing associated with the COVID-19 pandemic means that there are limitations on providing in-person training currently.

As there is uncertainty regarding how long the need for these restrictions will continue, we are currently developing the new ADOS-2 online training course and are aiming to deliver the courses later this year.

If you are interested to attend the ADOS-2 online training, please email us to and we will keep you informed on the future dates and details.
