How to request and autism assessment?
Getting diagnosed with autism is a significant and often positive turning point to receiving vital help and resources.
For many, receiving a formal diagnosis brings immense relief, clarity to understand their past experiences, access to workplace adjustments, and serves as an opportunity to connect with their peers.
This page is a clear, step-by-step guide on how to request an adult autism assessment.
1.Speak to your GP: Speaking to your GP about signs and symptoms is the first step of getting an autism assessment.
Preparing for your appointment:
In preparation to speak to your GP, spend a few days writing down a list of examples of autism traits.
2.Complete the AQ-10 Questionnaire: A tool used by GPs to measure traits. It can be helpful to take a completed AQ10 form to help confirm whether your symptoms are consistent with a possible autism diagnosis.
The Autism Spectrum Quotient (AQ-10) is a quick, 10-question screening tool that NHS doctors use to check if a full assessment is needed. Download and print a copy online, fill it out honestly, and calculate your score. If you score 6 or above, the NHS guidelines state your GP should offer you a referral.
3.Getting a referral: Once you have spoken to your GP, make sure to ask about waiting times and options.
If the GP agrees to refer you, ask them which specific local pathway or specialist team they are sending your paperwork to. A traditional referral will take the form of a letter sent from your GP, health care practitioner or educational professional to the diagnostic service that will carry out the assessment.
Note: Ensure you receive a copy of this referral letter.
You are also entitled to get a second opinion if you are refused a referral by your GP. Another option is to seek a private assessment that is independent from the NHS.
Important Legal Right: If you live in England, you have a legal right called Right to Choose.
What exactly is 'Right to Choose' (RTC?
In England, patients have a legal right to choose who provides their care. This includes mental health and neurodevelopmental assessments. If your local NHS trust has a long waiting list, you can ask to be referred to an independent, which includes some private clinics that have "Right to Choose" integrations with the NHS.
Who can use it
To be eligible for Right to Choose for an autism or ADHD assessment, you typically need to:
- Be registered with a GP in England.
- Some require Adults aged 18 or over
- Not already be under the care of a specialist team for that specific condition.
- Be seeking a first-time diagnosis.
It is important to work with your GP to ensure you understand your options and select the provider organisation that supports your individual needs.
