ADOS-2 Training Information and Qualification Requirements

The Delaware Network for Excellence in Autism (DNEA) is offering a 2- or 3-day Introductory/Clinical Training on the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2). The ADOS-2 is used for assessing and diagnosing autism spectrum disorder (ASD) across ages, developmental levels, and language skills.

What is the ADOS-2?

The Autism Diagnostic Observation Schedule, Second Edition (ADOS-2; Lord et al., 2012) is published by Western Psychological Services (WPS). It is a semi-structured, standardized assessment instrument that includes several play-based activities designed to obtain information in the areas of communication, reciprocal social interactions, and restricted and repetitive behaviors associated with a diagnosis of autism spectrum disorder (ASD).

The ADOS-2 helps practitioners to accurately assess and diagnose ASD and/or assist school teams when considering a special education eligibility of ASD. It can be used across all ages, developmental levels, and language abilities as part of a comprehensive evaluation.

The ADOS-2 provides a highly accurate picture of current symptoms, unaffected by language. It can be used to evaluate almost anyone suspected of having ASD—from 1-year-old children with no speech to adults who are verbally fluent. Additional information regarding the ADOS-2 can also be found online at WPS.

Who can administer the ADOS-2?

Anyone with a master’s degree (MA, MS, MSW, CAGS) in psychology, school counseling, occupational therapy, speech-language pathology, social work, education, special education, or a related field can administer the ADOS-2 if properly trained.

The course will provide a detailed training for professionals who plan to use the ADOS-2 in clinical or school settings.

What will it cost my agency?

The costs associated with the training are being covered by the Delaware Network for Excellence in Autism (DNEA). Qualified participants are in a unique position to receive training and post-training technical assistance support free of charge. Associated costs for your agency may include:

  • Time associated with attending either the 2 or 3-day online ADOS-2 training on June 13th -15th, 2022, provided by Norman Geller, Ph.D.
  • Required staff time to participate in two post-training technical assistance sessions (dates TBD) provided by Norman Geller, Ph.D.

Who is eligible to participate?

Qualified participants will be licensed professionals actively working with the autism population in Delaware. The training is designed for professionals who have background in autism and formal testing experience. Qualified participants will be individuals working in diagnostic settings or as part of a school-based evaluation team (e.g., school psychologists).

What is included?

Attendance is mandatory on June 13th and 14th. The third day (Wednesday, June 15) is the Toddler Module and is optional. ADOS-2 protocols and treatment manuals will be supplied to participants who require them.


Participants must be in attendance from 8:00am to 4:00pm using reliable technology that allows for the Zoom camera to be on for the duration of the entire training. Although not required, it is recommended that participants review Chapter Two of the training manual before the first day of training.

How do I request ADOS-2 training with the DNEA on June 13 – June 15?

Complete the online questionnaire before May 31, 2022. Submissions will be reviewed on a rolling basis. Once available training spots are filled, we will maintain a waitlist. You will be notified of your status within 72-business hours after submitting the attached questionnaire. We kindly request training cancellations be received by 9:00am June 10th so that your spot may be given to someone on the waitlist. Accommodations may be requested through the questionnaire.
