What is Right to Choose?
If your GP agrees that you should be assessed for autism, you have a legal right to choose who carries out that assessment. This is called Right to Choose, and it is part of the NHS Choice framework.

Before you start
You can use this route if you:
- You’re 18 or over and registered with a GP practice in England
- You do not already have an autism diagnosis
- You can travel to our clinic in Exeter or Plymouth for an in-person appointment
We cannot accept referrals for people who need urgent help with their mental health, or who have ongoing substance misuse. If either applies to you, your GP can advise on the right support first.
How to get referred
Book a GP appointment. Tell your GP why you think you may be autistic and how it affects your daily life, such as work, relationships or your mental health.
Ask to be referred to The Autism Service under Right to Choose. If your GP agrees an assessment is appropriate, the choice of provider is yours.
Share our referral form with your GP. Download our referral form and share it with your GP, who will complete it to refer you.
Your GP sends the referral to us. You do not need to do anything else at this stage.
1. We review your referral
We check it against the criteria for the service and may contact you for more information. We write to you and your GP, usually within 48 hours, to confirm whether it has been accepted.
2. We book your appointments
We talk you through each stage and answer your questions.
3. Clinical Interview
A clinician talks with you, and with someone who knew you as a child where possible, about your early life and your experiences now. This can take up to three hours.
4. Clinical assessment in clinic (ADOS-2)
You meet a clinician one-to-one for a set of structured activities and conversation.
5. Multi-disciplinary team diagnostic meeting
After your two assessments, our multidisciplinary team reviews everything gathered against the DSM-V criteria to decide whether you meet the criteria for an autism diagnosis.
6. Feedback and written report
We share the outcome with you at a feedback appointment and send a full written report with recommendations.
How long it takes
We can usually offer a first appointment within 14 weeks of your referral being received. Most assessments are complete within four to six weeks of starting.
How our autism assessment works
Every assessment we carry out follows NICE guidelines, so you can trust the outcome. In this short video, we explain how it works.
Live outside Devon?
You can still ask your GP to refer you to us. Your local NHS Integrated Care Board (ICB) will need to agree to fund the assessment first, and you will need to travel to Devon for at least one appointment. Our team can tell you whether this is likely to be possible based on where you live and any current restrictions in place with your local ICB.
Want to be seen sooner?
If Right to Choose waiting times don’t work for you, a private assessment may help you get clarity and support sooner, for adults and children.

Why choose The Autism Service?

Reports that open doors: You receive a clear, detailed report with practical recommendations for school, university, work or everyday life. Our reports are accepted by the NHS, schools, employers and local authorities.
Seen in person: We don’t cut corners. Our assessment pathway is the same today as when we started, and we hold firm that being seen in person when clinica guidance matters to getting an autism assessment right.

There are two main parts. The first is a detailed developmental history, taken in an interview of up to three hours with someone who knows you well, or with parents for a child.
