Accessing Autism & ADHD Assessments Through Right to Choose
Under the NHS Choice Framework, if your GP refers you for specialist care — such as an autism or ADHD assessment — you have the legal right to choose your provider.
At National Neurodiversity Assessments, we offer:
- Fully remote autism assessments for children (8 years+) and adults who are registered with a GP in any part of England.
- Hybrid Autism assessments for children (2 years+) and adults who are registered with a GP in any part of England, but are willing to travel to Exeter for the in-person part of the assessment.
- Hybrid Autism, ADHD and combined ASD/ADHD assessments for children and young people aged 6–18 years who are registered with a GP in any part of England, but are willing to travel to Norwich for the in-person part of the assessment.
Our hybrid assessments involve one face-to-face appointment in Norwich or Exeter, depending on the pathway you choose. Our clinics are conveniently located with train links and ample parking.
For fully remote assessments, all appointments will be online.
We do not currently prescribe ADHD medication, but can refer you on to a suitable service if required.
You can download information leaflets about the Right to Choose process (including your patient rights) and our assessments on our resources page.
Assessment Process
The NHS-funded Right to Choose pathway, step by step.
- 1
Step 1: GP Referral
Ask your GP to complete a Right to Choose referral to our service.
Once we receive your referral, we'll review the information provided and confirm whether we can accept the referral under the NHS Right to Choose pathway.
Please note that waiting times may vary depending on local Integrated Care Board (ICB) funding arrangements and referral volumes.
- 2
Step 2: Getting to Know You
We'll ask you to complete questionnaires and provide additional information to help us understand your experiences and support needs.
Depending on age and circumstances, we may also request information from parents, carers, schools, colleges, partners, or other professionals.
- 3
Step 3: Assessment & Diagnosis
You'll meet with our clinical team for your assessment either in-person or online.
ADHD Assessment
Our clinicians will complete a comprehensive assessment to understand your experiences and explore whether ADHD may explain some of the differences you experience in everyday life.
The assessment considers:
- Your developmental history
- Attention, concentration, activity levels, and impulsivity
- Strengths, challenges, and support needs
- Experiences at home, in education, at work, and in daily life
- Information from questionnaires and Creyos results (where applicable)
Autism Assessment
Our clinicians will complete a comprehensive assessment to understand your experiences and explore whether autism may explain some of the differences you experience in everyday life.
The assessment considers:
- Your developmental history
- Social communication and relationships
- Sensory experiences
- Thinking styles and interests
- Strengths, challenges, and support needs
- Experiences at home, in education, at work, and in daily life
Combined ADHD & Autism Assessment
A combined assessment brings together both the ADHD and autism assessment processes in a single pathway.
Our clinicians will explore your developmental history, experiences, strengths, challenges, and support needs to understand how ADHD and autistic traits may shape your day-to-day life.
This approach provides a comprehensive understanding of your individual profile while avoiding the need for separate assessments.
Diagnostic Outcome & Report
Following your assessment, our assessors will review all available information and consider whether the diagnostic criteria for ADHD, Autism Spectrum Disorder (ASD), or both are met.
You'll receive a diagnostic report that includes:
- A summary of the assessment findings
- Your diagnostic outcome
- An overview of strengths and support needs
- Recommendations and next steps
- 4
Step 4: Understanding the Outcome
We'll explain the assessment findings and what they mean for you, including any diagnosis where applicable.
You'll have the opportunity to ask questions, explore recommendations, and discuss support options and next steps.
- 5
Step 5: Next Steps
We'll discuss the recommendations arising from your assessment and help you identify any support, resources, or adjustments that may be helpful.
Where appropriate, this may include:
- Information and educational resources
- Recommendations for support in school, college, university, or the workplace
- Advice and recommendations for your GP
- Information about relevant local and national services
- Information about ADHD medication options (where appropriate)
Information for GPs
How to Refer your Patient
First, please make sure you have read and understood the acceptance and exclusion criteria.
If you are a GP within Norfolk and Waveney ICB, please complete this referral form and email it to us at rtcreferral.nna@nhs.net.
GPs in other areas can refer to us through eRS or complete this referral form (child) or this referral form (adult) and email it to us at rtcreferral.nna@nhs.net.
On receipt of your referral, we will email you with confirmation that your referral has been received. If your ICB is outside of Norfolk and Waveney or Devon, we must first seek funding approval from your local ICB.
We will then make contact with your patient to gather consent and information to start the assessment process. Our timeframe for assessment depends on ICB funding. We will assess your patient as soon as we are able. Following the MDT (Multidisciplinary Team) review, a detailed diagnostic report will be finalised and sent to you.
Which Assessment Pathway Should You Choose?
Current ICB Information
NHS Right to Choose Booking Updates
We know that waiting for an ADHD or autism assessment can be difficult, and we want to be as transparent as possible about our NHS Right to Choose waiting list.
While we accept referrals from across England, local NHS Integrated Care Boards (ICBs) may sometimes place restrictions on when providers can offer appointments in their area. These decisions are made by local NHS commissioners and can affect booking availability and waiting times.
Any ICB-specific booking updates will be provided on our Resources Page. Appointments are offered in referral date order within each assessment pathway.
