Azrieli Centre for Autism Research (ACAR): Transforming autism research, training and care -- improving lives via Open Science

Autism Diagnostic Observation Schedule - Second Edition (ADOS-2) Introductory Online Workshop

About the workshop

The Autism Diagnostic Observation Schedule - Second Edition (ADOS-2) is a widely used standardized assessment tool for diagnostic assessments of autism.

The online workshop is for professionals who would like to gain additional skills in diagnosing autism using the ADOS-2 across ages, developmental levels and language skills.

It covers modules 1, 2, 3 and 4 as well as the Toddler module, and includes discussion about:

  • the use of the ADOS-2 in making a clinical diagnosis
  • administration, scoring, and use of ADOS-2 algorithms
  • issues related to differential diagnosis, diagnosis in context, complex clinical situations, and report writing
  • current research on ADOS-2.
What is unique about our ADOS-2 workshops?
  • Workshops are kept small to allow for discussion and questions.
  • Our team has extensive experience with a wide range of ages and populations, including working with linguistically and culturally diverse populations, and we bring this experience to all our workshops.
  • We believe that the context in which diagnostic tools are used is important - we welcome discussion about attendees’ own clinical or research context so we can offer advice on best practices and helpful adaptations.
  • All workshops are led by certified trainers.



  Workshops are offered in either English or French.


Who can attend

  • New and experienced clinicians, researchers, and students who want to use or learn more about the ADOS-2
  • International and Canadian participants are welcome


Workshop dates

  • This online workshop is offered over 6 half-days, and is equivalent to the in-person ADOS-2 Introductory Workshop offered over 3 full days.
  • Participants must attend all sessions.


What participants had to say

"Mandy [Steiman] is an excellent resource. Even with delivering the training remotely, via Zoom, she was able to establish a good connection with all participants. The questions were really useful. Having participants from a variety of disciplines and levels of training was also really useful (e.g., hearing perspective from pediatricians, psychologists, clinic vs. other settings was great)."

- Julie, Psychologist (Napanee, Ontario) 

"Mandy [Steiman] clearly integrated theory and clinical practice in a highly nuanced, sophisticated, and accessible way. I appreciated how much emphasis she placed on the clinical application of the ADOS (i.e., placing it in the broader clinical context) as well as the importance of understanding the nitty-gritty behind codes (not simply getting the "right" code). Mandy is an exemplary 'scientist-practitioner' and seamlessly integrated her clinical experience with her prowess as a researcher, which was highly effective. She showed remarkable breadth and depth of the subject matter. The workshop was organized thoughtfully, deliberately, and delivered dynamically! The training was highly structured and organized; Mandy also showed great flexibility and was able to pivot quickly if needed."

- Kelsey, Clinical Psychologist (Charlottetown, Prince Edward Island)

"I really valued the in-depth focus on watching the specific modules and coding independently, followed by the coding discussion. I definitely learned the most here. I appreciated that the presenter was able to go back to certain time points in the video to show more subtle behaviours or certain behaviours that needed to be coded."

- Angie, Clinical and School Psychologist (Belleville, Ontario)

"[The workshop] has 'demystified' the ADOS for me (in a good way)... it reassured that my practices and understanding of autism symptoms, presentation and diagnoses are all right. This is helpful in terms of recognizing that experienced school/clinical psychologists can appropriately diagnose and consider autism queries to help families access needed services. I will also use some of the approaches and ideas in my comprehensive assessment sessions with students, even if I don't administer/score the complete tool. I was already using observational tips from training yesterday when working with a student who has symptoms!"

- Amy, Psychologist (Kingston, Ontario)

"This workshop has allowed me to get the skills and training necessary to conduct an ADOS-2 assessment. It will also allow me to assist other graduate students in my lab in the administration of the ADOS-2 for their respective studies. Receiving this training on one of the golden standards for autism diagnosis will be extremely valuable as I plan for a career as a clinical researcher."

- Mira, Doctoral student, School/Applied Child Psychology (Montreal, Quebec)
