The NHS pathway for autism in Scotland

GP referral, waiting times, your rights, and what to do if you are struggling to access assessment

How NHS referrals work for autism assessments

NHS autism assessment in Scotland begins with your GP. A GP cannot diagnose autism. They can only refer you for a specialist assessment. Where you are referred depends on your age.

Under 18: Referral typically goes to Child and Adolescent Mental Health Services (CAMHS) or a dedicated neurodevelopmental team, depending on your health board. Some boards have separate paediatric neurodevelopmental pathways; others route all assessments through CAMHS.

Adults: Referral goes to adult psychiatry, clinical psychology, or a neurodevelopmental service. Provision varies significantly by health board. Some areas have dedicated adult neurodevelopmental services; others assess autism through general adult mental health services, or have no adult autism pathway at all.

This inconsistency across health boards is one of the most significant structural problems in autism care in Scotland. Your access to a timely, thorough assessment depends substantially on where you live.

Right to Choose does not apply in Scotland

Right to Choose is an NHS England policy that allows patients registered with an English GP to choose from a list of approved providers, including some privately run services the NHS will fund. It does not apply in Scotland.

Scotland has its own NHS system, accountable to the Scottish Government. If you are registered with a Scottish GP, Right to Choose is not available to you, regardless of what you may read in UK-wide guides or online communities.

Waiting times

Waiting times for NHS autism assessment in Scotland vary significantly by health board and have grown considerably in recent years. According to a June 2025 Scottish Parliament research briefing (SB 25-25), some health boards report children waiting over five years for assessment, and several boards have neurodevelopmental waiting lists exceeding 7,000 children.

Adult autism assessment services are significantly underdeveloped. In some health board areas, no adult autism pathway exists at all.

ADHD Scot has submitted Freedom of Information requests to all 14 health boards. Responses are published as they arrive.

What to do if your GP won't refer you

GPs can and should refer you for autism assessment if you present with relevant traits and request a referral. If your GP declines:

  • Ask them to explain their reasons in writing, which creates a record and sometimes prompts reconsideration
  • Ask for a second opinion from another GP at the same practice
  • Put your referral request in writing
  • Contact Patient Advice and Support Service (PASS) for free, independent advice on your rights within NHS Scotland

If you cannot wait

If you cannot wait

If the waiting time in your area is too long, a private autism assessment is an option. See our going private for autism guide for what to look for, what a good assessment includes, and what questions to ask before you book.

What to expect from an NHS assessment

According to SIGN 145 — Assessment, diagnosis and interventions for autism spectrum disorders, Scotland's clinical guideline for autism, a thorough assessment should include:

  • A detailed clinical interview covering your developmental history, current presentation, and how your traits affect daily life
  • Use of validated diagnostic instruments: for adults, this may include structured tools such as the ADOS-2 (Autism Diagnostic Observation Schedule) and the RAADS-R (Ritvo Autism Asperger Diagnostic Scale — Revised); for children, the ADOS-2 and ADI-R (Autism Diagnostic Interview — Revised) are the recognised gold-standard tools
  • Collateral history: information from someone who knew you as a child, such as a parent, sibling, or early school records. This is particularly important because autism must have been present since early development
  • Consideration of co-occurring conditions, including ADHD, anxiety, depression, and sensory processing differences
  • A written diagnostic report with a clear outcome and explanation of the clinical reasoning

Assessment for autism is typically more involved than for ADHD. In many services it is multi-disciplinary, involving a combination of a psychiatrist, psychologist, specialist nurse, and sometimes a speech and language therapist or occupational therapist. This is especially common in children's services.

If your assessment does not appear to include these elements, you are entitled to ask why.
