A few of our frequently asked questions about this course
The Autism Diagnostic Interview-Revised (ADI-R) is a structured, investigator-based interview 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, interview structure 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, suitable for your CPD portfolio, revalidation and appraisal records. It can also be used for insurance provider credentialling and revalidation portfolios.
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.
