ADOS-2 Training


Introductory/ Clinical Workshop 

Autism Diagnostic Observation Schedule-2nd Edition (ADOS-2) 


The A.J. Drexel Autism Institute is collaborating with The Children's Hospital of Philadelphia's Center for Autism Research (CAR) to offer a 2- or 3-day training on the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2). Due to the COVID-19 pandemic, this workshop will be offered virtually, rather than in-person. 

  • July 13 - 14, 2022: 2-day ADOS-2 Introductory/ Clinical Training Workshop covering Modules 1-4 - SOLD OUT
  • July 13 - July 15, 2022: 3-day ADOS-2 Introductory/Clinical covering Modules 1-4, PLUS one-day Toddler Module Training Workshop - SOLD OUT
  • September 28 - 29, 2022: 2-day ADOS-2 Introductory/ Clinical Training Workshop covering Modules 1-4
  • September 28 - September 30, 2022: 3-day ADOS-2 Introductory/Clinical covering Modules 1-4, PLUS one-day Toddler Module Training Workshop

Both ADOS-2 training workshops provide experienced autism professionals with introductory training on the use of the ADOS-2 in clinical settings across ages, developmental levels, and language skills. The training will be led by two ADOS-2 trainers: Dr. Elisabeth Sheridan, the Director of the Clinical Core at the A.J. Drexel Autism Institute, and Dr. Whitney Guthrie, scientist at the CHOP’s CAR program and co-author of the ADOS-2 Toddler Module.

Requirements: These workshops are designed for both clinicians and researchers. 

  • For clinicians with a prior background in autism and formal testing, the 2-day Introductory/Clinical Workshop is sufficient to support use of the ADOS-2 to inform the diagnosis of autism spectrum disorder. Physicians, psychologists, social workers, occupational therapists, speech-language pathologists, social workers, and other clinical professionals will be better prepared to make medical diagnoses and educational placement decisions and evaluate programs after completing the workshop.
  • Individuals with less background in testing but, who provide service for individuals and families affected by autism, may take the workshop for informational purposes.
  • For researchers, this workshop is a prerequisite for the Advanced/Research Reliability training that this required in order to use the ADOS-2 for research purposes. The ADOS-2 Advanced/Research Reliability workshop is a 3-day workshop designed to help trainees achieve the high cross-site inter-rater reliability required in published research.


*Please note that ADOS-2 training does not take the place of state regulations regarding making an autism diagnosis. Instead, the ADOS-2 is designed to be one component of an autism evaluation for professionals qualified to make this diagnosis. 

It is recommended (though not required) that participants have access to an ADOS-2 manual before, during, and after the training workshop. This can be purchased through the publisher, Western Psychological Services (Product #: W-605M). However, it cannot be purchased at the workshop.
