ADOS-2 Clinical Training

The ADOS-2 is a semi-structured, standardized measure of communication, social interaction, play, and restricted and receptive behaviours synonymous with autism spectrum disorder (ASD). It is widely considered the ‘gold standard’ measure of behavioural observation for assessment and diagnosis of ASD. With updated protocols and the addition of the Toddler Module, the ADOS-2 provides a highly accurate evaluation of current behaviour in individuals from 12 months of age to adulthood, from individuals who are nonverbal to individuals who are verbally fluent. By observing and coding these behaviors, you can obtain information that informs diagnosis, treatment planning, and educational placement.

Through completion of this introductory course, you will:

  • Learn the differences between clinical and research use of the ADOS-2
  • Learn how to select the appropriate module for working with different clients
  • Learn how to administer the tasks within each module
  • Learn how to code the specific items within each module
  • Observe demonstration administrations with the ADOS-2 and practice scoring and coding
  • Obtain experience that will support your future administrations with the measure as you work towards independent clinical use

Your Involvement

  • Attend the 3 day training session
  • Read and bring your own ADOS-2 manual (available through WPS; ADOS-2 protocols will be provided)
  • Be prepared to engage in observation and scoring of two demonstration administrations with volunteer individuals with ASD
  • Be prepared to discuss behaviours observed during the demonstration administrations and the coding for each administration with the group
