Face-to-Face ADOS-2 Training with Lucy Sanctuary

What does Face-to-Face ADOS-2 training with Lucy Sanctuary involve?

  • Pre-course reading, pre-course video clips to watch of ADOS-2, anonymised reports, and tasks to help familiarise you with the assessment.
  • An introduction to, and training in administration and coding of Modules 1– 4.
  • Watching and coding videos of different modules (Module 1-4).
  • Coding discussions, and learning to calculate reliability, as everyone that does the ADOS-2 has to aim for 80% reliability in their coding (this will be explained on the course).
  • Information on using the ADOS-2 in different settings, developing your skills as an ADOS-2 practitioner, and attending reliability meetings to develop and maintain coding reliability.
  • 3 post-course videos to code independently.
  • A Zoom meeting with participants on the training course after the course to discuss coding of one of the post-course videos to increase understanding of codes and confidence in coding.
  • Individual feedback to help participants learn more about their coding, their strengths, and areas they need to focus on.
  • Participants record themselves administering at least 2 ADOS-2 tasks and share this with Lucy to get feedback on administration.
  • Two contacts with Lucy for advice, support, recommendations, supervision up to 6 months post training.  
  • Participants receive a certificate for completing the course when they have coded the post-course videos so that they can start their ADOS-2 journey and administer the ADOS as part of the diagnostic process.

Lucy provides 2-day and 3-day face-to-face ADOS-2 training courses. Both training courses are intense and cover a lot of information. Face-to-face training provides opportunities for everyone to participate in discussion, to ask questions, to work with partners and discuss what we are doing in groups, which helps process and learn the information we cover. It also provides opportunities for Lucy to see when participants are confused, or do not understand, and to directly help them. Lucy is available in breaks and at the end of the day to answer questions and to help participants.

Lucy likes the personal aspect of live training and the extra support that it enables her to give people on the course. Lucy’s training includes pre and post training resources and tasks, an extra on-line meeting to code one of the post-course videos, feedback on administration of ADOS-2 tasks and two opportunities to contact her for support to all participants because she is dedicated to helping others learn how to carry out the ADOS-2 as part of the diagnostic assessment process and it is a difficult assessment that takes time to learn and to feel confident administering and coding.

Autism Assessment

The Autism Diagnostic Observation Schedule 2nd Edition (ADOS-2) is used for assessing and diagnosing autism across all ages, developmental levels, and language skills. It is one part of the diagnostic process (see diagram below) based on the DSM-5 or ICD-11 diagnostic criteria for autism and has been referred to as the ‘gold standard’ observational assessment for autism (Kanne, Randolph, & Farmer, 2008).

ADOS-2 Training face to face

The ADOS-2 was developed to standardise observations across different children/young people/adults, different clinicians, and different sites.  It is a semi-structured assessment that provides an opportunity to elicit and observe behaviours associated with Autism, e.g., differences in non-verbal communication, sensory differences, a preference for sameness, differences in social communication and interactions.

Frequently Asked Questions about ADOS-2 Training

Who can attend the ADOS-2 Training?

Participants must have at least an undergraduate degree in a relevant subject (e.g. psychology, education) and some experience of autism, e.g., relevant work experience. We welcome participants from a range of professional backgrounds, including psychologists, psychiatrists, paediatricians, speech and language therapists, occupational therapists, social workers, nurses, psychotherapists, researchers, and education specialists. If you have any questions about your eligibility to attend the course, click here to contact Lucy.

Does it matter if I have not seen an ADOS-2 assessment?

No, but it really helps if you have. There is a LOT of information on the 2- and 3-day course and if you have seen an ADOS-2 assessment, it will help you to understand some of the information we will be covering and give it a clearer context. I really recommend you try to do this if you can.

If you can’t, do not worry because I give you access to parts of an ADOS-2 assessment to watch before the course, which will help you and you will be able to have access to this after the training for a short time.

Can I start administering the ADOS-2 straight away after the training?

After completing the ADOS-2 training, all participants have to complete a post-course accreditation exercise (as described in information about the ADOS-2 training).  The training is an introduction to the ADOS-2, and like learning to drive, practitioners need practise to feel confident using the assessment and coding it live. It is recommended that you shadow colleagues and complete some practice assessments before using the tool in clinical or research work. Administrators are considered ‘reliable’ in their coding when they consistently achieve a minimum of 80% agreement with consensus scores. If the reliability rates are below the required level, it will impact upon the validity of the assessment tool. A good way to become skilled at the ADOS-2 is to film assessments and watch them back, and to have input from a trainer (or another clinician/researcher who has demonstrated that they are consistently reaching a minimum of 80% reliability in line with international calibration).

 Can I diagnose autism after this training?

NHS England maintain that assessment must be carried out by a multi-disciplinary team, and diagnosis is given by a health professional trained in differential diagnosis, e.g., a psychiatrist, paediatrician, or clinical psychologist. However, other professionals are often involved in different aspects of the assessment process, e.g., doing the ADOS-2/ADI-R. It is good clinical practice to have at least two professionals involved in the diagnostic process. Whoever gives the diagnosis should be appropriately trained to consider whether the clinical presentation could be better explained by another condition, e.g., intellectual disability, ADHD, OCD, Conduct Disorder, trauma and stress related disorders. NHS England have published guidelines (2023) with further information (see Appendix B).

How do I reach and maintain reliability?

It is important that we all code the same things in the same way when we administer the ADOS-2, this is part of the standardisation, so it is essential that administrators do not drift from the coding consensus. You can check reliability by attending reliability workshops. For example:

GAIN (Global Autism Interactive Network) This is American and International trainers who run regular reliability meetings, covering all modules. They are not expensive, and it is a way of making sure you are reliable with the international consensus.


In the UK, the following reliability training is available:

Marianna Murin and Emma Woodhouse run workshops jointly:  https://www.asdirections.com/

The National Psychology Clinic: https://www.thenationalpsychologyclinic.co.uk/

ADOS2Training run reliability workshops: https://ados2training.co.uk/reliability.html

How often should I attend reliability meetings?

The ADOS-2 manual recommends that administrators attend reliability meetings on a regular basis to check that they are maintaining reliability and not ‘drifting’ with coding and/or administration. There is no specific guidance about the frequency with which ADOS-2 administrators should attend reliability meetings- it is the responsibility of the individual / organisation to decide how often this is required.

Do I need to be research reliable?

Some research projects require additional reliability certification. This is a separate process which involves recording and submitting a video of you administering an ADOS-2, along with your coding. A trainer will then go through this video and provide specific feedback on both administration and coding. If you require this, please contact Lucy.

Are your courses accessible for specific learning needs?

Absolutely. If you notify Lucy with what adaptations you need, she will do everything that she can to make sure that training is inclusive and accessible.

Do I need to have an ADOS-2 kit, a manual or module booklets to do the ADOS-2 training?

Lucy will show you an ADOS kit and use activities from the modules to show you how they are administered, but you do not need one to do the training. You will need access to an ADOS-2 kit to administer the assessment after the training, but most organisations have kits. The kit is part of the standardised conditions, so it is very important that you use it to do the assessment.

You don’t need a manual to do the course, but it is advisable to have one, it is very informative and gives you much more information than the module forms do. Many organisations have these, but you might want to buy your own.

Lucy will give you module forms to use during the training and for the post-course coding that you are required to do.

How many people are on the face-to-face training?

Lucy runs training with different sized groups, as different sizes suit different people. There is a lot of information in the training and some people prefer to have smaller groups. The smallest group Lucy runs is 6 people and the largest is 20. The wonderful thing about face-to-face is that everyone can see each other, they can talk, help each other, ask questions, have partner and group discussions and share experiences.

How can I discuss ADOS-2 queries once I have completed the course?

You can contact Lucy with questions, you can find a supervisor, e.g., a more experienced clinician at your workplace, or a trainer, and you can attend reliability meetings, as described above.
