NB Pearson only offers the 2-day clinical workshops. It does not offer the 5 day research reliability training - this is offered independently by trainers whose details can be found  on the Weill Cornell Medical College website  


About the course

This workshop is for professionals unfamiliar with the ADOS-2; it will provide an introduction and guidance on the use of the ADOS-2 for the purposes of clinical assessment.

Our experienced trainers will provide an overview of the ADOS-2 and demonstrate administration and scoring, operationalising diagnostic criteria for ASD. You will have the opportunity to practise scoring with guidance from the trainers on the nuances of administration and coding the ADOS-2.

The workshop focuses primarily on Modules 1 to 4; materials are provided in order to complete training in the Toddler Module following the workshop.

An important component of the workshop is the Pre and Post Course Materials which are included in the cost of the workshop. These materials include two DVDs focused on Modules 1 to 4 and one DVD/Guidebook providing training in the Toddler Module.

Participants should familiarise themselves with the pre-course materials in preparation for the workshop. After the workshop, participants use the post-course materials to reinforce skills learned and complete training in the Toddler Module.

The Pre and Post Course Materials amount to approximately 10 hours of required self directed learning.

The UK trainers will be one of those outlined on the list above. The actual trainer will be detailed on the relevant course booking form.


Who should attend

  • For clinicians with a prior background in autism and formal testing this 2-day workshop is sufficient to support use of the ADOS-2 to inform the diagnosis of autism and autism spectrum disorders. Physicians, psychologists, occupational therapists, and speech-language therapists will be better prepared to make diagnostic and educational decisions, and evaluate programs after completing the workshop. In addition it is recommended that at least one person from each setting/organisation using ADOS-2 has attended a research reliability training.
  • Individuals with less background in testing but who provide services for individuals and families affected by autism may take the workshop for informational purposes.
  • Researchers who plan to use the ADOS-2 in research need to attend in-person research workshops. Pearson does not run research reliability workshops, but it is recommended that at least one person from each setting/organisation using ADOS-2 has attended a research reliability training. The 5 day research reliability training is offered independently by trainers whose details can be found on the designated UK ADOS trainers' page.
  • If you require longer in-person training with less self-directed learning, then it is recommended you attend a full research reliability training event.

Note: Attendance on the course does not guarantee qualification to purchase ADOS-2; access to test materials is governed by our qualification criteria, please see our registration information page for further details.

It was a really good course and the facilitator was great. She was really good at explaining the assessment and how this was carried out. it was a very practical focused training and made it clear around how it was to be implemented. I feel ok about carrying the ADOS - 2 out after this.

The workshop was highly informative, I feel confident in my understanding of the assessment tool following the workshop.

Very well thought out training package that was well delivered and easy to follow/understand. Helped immensely with learning the practical tips of completing an ADOS-2 and how/when it should be used in context to practice.

It was enormously useful to have the course facilitated by such a competent & knowledgeable trainer who is simultaneously engaged in clinical practice, research, development & training.

Covered more than I expected in 2 days. The video of the child without Autism was very useful to watch and code alongside the videos of those with Autism.

It was an excellent introduction, just unfortunate not to have the opportunity to try it out yourself but I understand that that is beyond the remit of this condensed course.
