A few of our frequently asked questions about this course
The Autism Diagnostic Interview-Revised (ADI-R) is a structured, investigator-based interview developed by Lord, Rutter, and Le Couteur. Conducted with a parent or primary caregiver, it covers Social Interaction, Communication, and Restricted/Repetitive Behaviour. Alongside the ADOS-2, it is considered the gold standard for autism assessment due to its rigorous psychometric properties, extensive research base, and global clinical adoption across all age groups.
This course is designed for qualified healthcare professionals involved in autism assessment, including clinical psychologists, psychiatrists, paediatricians, specialist nurses, speech and language therapists, occupational therapists, and MDT autism assessment team members. Prior clinical experience with neurodevelopmental assessments is recommended.
The course runs as a 2 full-day programme (09:00–17:00) and is delivered entirely remotely. Three modules cover ADI-R foundations, administration and coding, and scoring and clinical interpretation — with interactive case discussions, practical exercises, and a live Q&A throughout.
Yes. All participants receive a CPD certificate upon completion awarding 8 CPD hours, submissible to BPS, HCPC, NMC, GMC, and GPhC. It can also be used for insurance provider credentialling and revalidation portfolios.
Participants receive 8 clinical resources including the ADI-R Quick Reference Card, Coding Algorithm Worksheet, Sample Interview Probes Guide, DSM-5/ICD-11 Cross-Reference Chart, Clinical Report Writing Template, Differential Diagnosis Guide, ADOS-2 Integration Overview, and NICE Guidelines Summary. All materials are digital with lifetime access.
This course provides specialist clinical training in the application, interpretation, and clinical use of ADI-R findings within autism diagnostic practice. Completion equips clinicians to confidently use and interpret ADI-R findings as part of their wider diagnostic work. The course is not designed for research purposes — clinicians intending to use the ADI-R in research require formal research reliability certification, which is a separate process. Please contact info@globaladhdnetwork.com for tailored guidance.
To become an autism assessor, you typically need: (1) a registered clinical or psychological background such as a nurse, doctor, clinical psychologist, paediatrician, speech and language therapist, occupational therapist, or pharmacist with specialist training, (2) training in evidence-based autism assessment tools — most commonly the ADI-R (Autism Diagnostic Interview-Revised) and the ADOS-2 (Autism Diagnostic Observation Schedule, Second Edition), and (3) supervised clinical experience in autism diagnostic practice, ideally within a multidisciplinary team setting. Specific registration and qualification requirements vary by country. Many clinicians begin with CPD-accredited courses in autism diagnosis and progress to the gold-standard ADI-R and ADOS-2. Global ADHD Network supports clinicians internationally — for tailored guidance on your pathway, contact info@globaladhdnetwork.com.
Requirements vary by country, but most clinics and employers expect: a registered clinical background, training in evidence-based autism assessment aligned with international guidance such as DSM-5 and ICD-11, and competency in validated diagnostic tools such as the ADI-R and ADOS-2. Multidisciplinary team-based assessment is widely recommended best practice. Common professional backgrounds include consultant psychiatrists, clinical psychologists, paediatricians, mental health nurses, advanced nurse practitioners, speech and language therapists, occupational therapists, and pharmacists with specialist neurodevelopmental training. In the UK specifically, clinicians are typically registered with the NMC, GMC, HCPC, BPS, or GPhC.
The ADI-R and ADOS-2 are complementary tools that together form the gold-standard autism diagnostic assessment. The ADI-R is a structured developmental interview conducted with a parent or primary caregiver, covering three domains: Social Interaction, Communication, and Restricted & Repetitive Behaviour. The ADOS-2 is a direct observational assessment conducted with the individual being assessed, using structured activities to observe social, communicative, and play behaviours. Most NICE-compliant autism assessments use both tools alongside developmental history, clinical observation, and consideration of differential diagnoses such as ADHD, anxiety, or language disorder.
In most clinical and NHS settings, training in both the ADI-R and ADOS-2 is considered best practice for comprehensive autism assessment. The ADI-R captures developmental history through caregiver interview; the ADOS-2 captures real-time direct observation. Used together they provide the most robust evidence base for diagnostic conclusions and align with NICE guidance. Global ADHD Network offers specialist clinical training in both — contact info@globaladhdnetwork.com for information on training pathways.
Private autism assessment fees vary significantly by country and region. In the UK, private autism assessments typically cost between £800 and £2,500 per assessment, with London and major city practices often charging £1,500–£2,500. In the US, Australia, and Europe, equivalent assessments often command similar or higher fees. Clinicians working in private practice can therefore generate substantial revenue per assessment, depending on clinical setting, country, and assessment complexity. Salaried roles within public healthcare systems vary by country and pay band. Across all major markets, demand for qualified autism assessors significantly outstrips supply.
Yes — demand for qualified autism assessors is at an all-time high across all major healthcare markets and substantially outstrips supply. In the UK, NHS adult autism assessment waiting lists currently exceed 3–5 years in many regions, with some clinics reporting waits of 4+ years from referral. Children's autism assessment waiting lists average around 32 months in many community paediatric services. Similar diagnostic backlogs are documented across the US, Australia, Canada, and much of Europe. Demand for self-funded private autism assessments has grown sharply worldwide. The structural undercapacity in the autism diagnostic workforce creates significant career opportunities for qualified clinicians entering the field.
The timeline depends on your existing clinical background. For clinicians already registered with their professional body, the practical training pathway can typically be completed within 6–12 months. This includes core autism diagnostic training, specialist instrument training (ADI-R and ADOS-2 clinical use), supervised clinical practice, and integration into multidisciplinary teams. Career changers without an existing clinical qualification will need to complete their underlying professional training first.
Yes. The autism assessment workforce in most countries includes nurses, advanced nurse practitioners, mental health nurses, pharmacists with specialist neurodevelopmental training, clinical psychologists, paediatricians, GPs, speech and language therapists, and occupational therapists. Multidisciplinary team-based assessment is widely recommended best practice and by definition involves several professional backgrounds. Many Global ADHD Network trainees come from non-doctor clinical backgrounds and successfully establish autism assessment practice. Contact info@globaladhdnetwork.com for guidance on the pathway most suited to your professional registration and country.
Alongside ADI-R clinical training, most autism assessors complete: (1) foundational autism diagnostic training covering DSM-5 and ICD-11 criteria, clinical assessment pathway, and diagnostic formulation, (2) ADOS-2 clinical training for the observational component, (3) training in differential diagnosis covering ADHD, anxiety, intellectual disability, and language disorder, and (4) clinical report writing and diagnostic decision-making training. Global ADHD Network offers comprehensive training pathways for clinicians worldwide — contact info@globaladhdnetwork.com for a tailored learning plan.
NHS autism assessment waiting lists vary significantly by region but are universally long. Adult autism assessment waits commonly exceed 3–5 years from referral, with several large NHS services reporting 4-year waits as of 2026. Children's autism assessments average around 32 months in many community paediatric services. NHS Right to Choose pathways can offer shorter waits (typically 14–28 weeks for adult autism) but availability depends on local ICB commissioning. These extended waits have driven substantial growth in the private autism assessment sector.
Yes. Many specialist autism assessment courses, including Global ADHD Network's ADI-R clinical training, are delivered remotely via interactive online sessions combined with self-study modules. Remote delivery does not compromise training quality for clinically-experienced professionals, and allows clinicians worldwide to access specialist instruction without travel costs. Global ADHD Network welcomes international delegates and is expanding its training offering across the UK, US, Europe, Australia, and beyond. For practical experience, in-person observership or supervised clinical practice is recommended alongside online training.
amazing course
This was soo enlightening and encouraging and critical as i am in the process of career change.
The course has given me a strong foundation in adult ADHD assessment. I still have more to learn but it's been a valuable starting point
I have thoroughly enjoyed this course, it's comprehensive, a lot of information in one day but the structure of the course, the knowledge sharing, and course delivery was excellent. I look forward to being able to use this, for my own professional development, but, also, so that I can hopefully improve outcomes, and quality of life for others. Thank you.
I had a lot of knowledge about ADHD as a condition (both due to my personal experience as well as the clients I work with) but having that deep understanding of different management techniques and what to consider with medications is massively helpful. Thank you for teaching in a way that makes sense to me!
Incredibly interesting and informative. Clear instructions on how to interpret and provide ADHD diagnoses and examples of this. I feel that I have a much clearer understanding to work with clients moving forward
Very Interactive
Fantastic course with wonderful learning. I am looking forward to pursuing a further career in this area asap!

More time spent on going through the DIVA would have been beneficial. Almost constant interruptions from course participants was problematic for how the day progressed - the facilitator was very calm with attempting to manage the group, however the constant questions/comments continued.
Very informative. Thank you
The course created a clear and structured framework for assessing ADHD in both Adults and Children. Focusing in the NICE guidelines criteria and the correct usage of diagnostic screening. How to assess clinically both from the client themselves and a third party.
Great course
GREAT COURSE, VERY THOROUGH AND WELL DELIVERED
Masters in Pharmacy
Fantastic course. I am thoroughly confident that it has given me the knowledge and skills required to perform diagnostic assessments for ADHD. The trainer exceptionally delivered the course content along with his own inside insights to ADHD. I would love to collaborate with him regarding setting up transitional services for neurodivergent clients moving from child to adult services given the huge gap there and my paediatric nursing experience. Please get in touch!
It was good. Would be good to know if someone comes (adult), what documents/ forms/ letters needs to be filled to diagnose them with ADHD, along with the DIVA.
