Read more about the trainer >

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 designated UK ADOS trainers' page


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 trainer will describe the ADOS-2 and demonstrate administration and scoring, operationalising diagnostic criteria for ASD. You will have the opportunity to practice scoring with guidance from the trainer 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.


Endorsed by the College of Occupational Therapists

We are proud that our ADOS-2 Clinical Workshops have been endorsed by the College of Occupational Therapists who made several commendations:  

  • Excellent learning material including workshops and DVDs.
  • Well structured with pre-course work and post course work to help consolidate the learning.
  • Well supported, as learners have the opportunity to seek support following completion of the course to further facilitate their learning.



Steadily paced and clearly explained. Videos and coding help.

Clinical Psychologist, Feb 2014


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.

Lead Clinical Psychologist, Feb 2014


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.

Educational Psychologist, Feb 2014


Lots of relevant and useful information

Speech and Language Therapist, Feb 2014


Fiona Scott made it very interesting and informative - well-presented and at the right level.

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.
