About the workshop

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


  • This workshop is offered in English
  • A French workshop will be held in May 2023
