Our autism assessment process is the same for both adults and children. It’s made up of a number of elements, including:
Our initial autism assessment (charged at £99 for adults and £186 for children), conducted by a therapist with specific neurodiversity training and experience.
During this session, we use the autism spectrum quotient test (AQ-10) as part of a structured screening process to help determine whether a full autism assessment is the most appropriate step for you.
We’ll also explore:
This initial assessment can take place at the enquiry stage.
An autism assessment includes many different parts. Our specialist will use a different tool to help them understand the current challenges you’re facing. These tools include:
Our specialists will speak to key people in your life, which may include parents/guardians (if nominated), in order to explore your developmental history. For children, this stage will often need input from schools too. We'll ask you for the contact details for these people, and contact them directly.
There will also be a session, the Autism Diagnostic Observation Schedule (ADOS), where our specialists observe and assess for any autism traits. This is conducted and carried out by two specialists, and focuses on your behaviour and/or reactions during the session.
After an assessment, there will be a multidisciplinary team (MDT) meeting, to agree on and formalise your diagnosis.
Following on, we’ll provide you with a comprehensive outcome report, based on NHS and National Institute for Health and Care Excellence (NICE) standards.
There will also be a feedback meeting to talk about the outcomes of your assessment and provide any recommendations for further support.
To start the autism assessment process, you'll need an initial assessment to ensure you are suitable for the full autism assessment. This initial assessment costs £99 for adults and £186 for children.
Should we then recommend that you proceed to the full autism assessment, this costs from £2,150. If you're already in treatment with Priory, you may not need to have the initial assessment.
The autism assessment process includes:
This applies to both adults and children.
The full process usually takes 4 to 6 weeks from start to finish, depending on availability and the complexity of the case. Appointments may be available in as little as 2 weeks.
No, you don’t need a formal GP referral to be able to access our autism assessment process. The exception to this is when a person needs to see a psychiatrist before entering the process.
Yes. A formal diagnosis can help you or your child access reasonable adjustments and tailored support at school, college or in the workplace. The outcome report can be shared with educational or occupational settings to aid understanding and secure the right support.
We can offer autism assessments for children from the age of 4 years.
Depending on the age of the young person, parents/guardians can be involved in all stages of the assessment process. This can be discussed and agreed upon during the initial screening session.
During the ADI-R stage of the autism assessment process, we need to gather information on the person’s developmental history from as many people as possible. Therefore, parents/guardians and other key people in the person’s life will need to be involved. This is the case for both adults and children.
Most autism assessments can be conducted by either a therapist or a psychologist, but some people may benefit from seeing a psychiatrist. The type of specialist you’ll see can depend on a number of factors. These include:
We can guide you through the options during your initial conversation with us, and help to determine which would be the most appropriate for you. If you start on the therapist or psychologist route, but it becomes clear that you’d benefit from a psychiatric assessment, then we can refer you to one of our psychiatrists quickly and easily.
If your assessment needs to be conducted by a psychiatrist, the cost of this is typically around £2,500, though this may vary depending on individual consultant fees.
