All of our Clinical Adult Autism Assessments are carried out by Jess Hendrickx and signed off by Dr Linda Buchan (Consultant Clinical Psychologist and founder of Axia-ASD)

Our wait times are usually within 8 weeks, which is considerably shorter than the NHS and many private providers.

The Clinical Autism Assessment is ideal for those who seek confirmation that they are autistic and gain a greater self-understanding. In our experience, our Clinical Autism Assessment is often considered to be more than sufficient evidence by employers for employment support and for higher educational purposes (university), but we would advise that this is checked with your employer/university before proceeding.

As with our non-clinical assessment, the process takes the form of an informal, but structured conversation following the pre-assessment completion of a questionnaire. We do not use clinical tools such as the ADOS-2 during any of our assessments because we do not believe that these are suitable for use with adults without an intellectual disability. The assessment is based on the DSM-5 and ICD-11 diagnostic criteria, but these are applied in a manner that should cause no concern to autistic females or others with non-'classic' Autism profiles. We have a wealth of experience assessing people who do not present in a ‘classically’ autistic way. Our assessor, Jess, is also AuDHD and understands what it is like to navigate the world as a neurodivergent person.

As part of the clinical assessment, we can carry out an ADHD screening, if this is wanted. This is not a full assessment or clinical diagnosis, but it may help you to decide whether or not to pursue a clinical ADHD diagnosis from the appropriate medical professional. We use the diagnostic criteria for ADHD as a checklist, asking questions about both adult and childhood.

**Please note: We cannot prescribe or make any recommendations about medication**

As with any private provider of clinical assessments, we cannot guarantee that our clinically supervised assessment will be accepted by the NHS, education providers, employers, or for claiming benefits. If you need a clinical diagnosis for any of these reasons, please check beforehand that what we offer will be accepted.

We cannot assess anyone under the age of 18. Children need to be assessed in person, by a multidisciplinary team, and we do not have the facilities to provide this. If you are hoping to have your child assessed, our recommendation would be Axia.

Testimonials

“Thanks so much for yesterday for being a mirror and giving me more insight about the Audhd. I really feel that your work is lifesaving. At least that is the impact I feel.


“My autism assessment was a very positive experience, in spite of the anxiety and nervousness that I felt in the run up. Jess was very easy to talk to, creating a safe space to discuss my life experiences, and added some interesting insights. I felt supported and heard, and am very glad that I took this step.”


“I have to say, from the bottom of my heart, how absolutely wonderful and delightful the ‘assessment’ was! I just had a really enjoyable time talking with you. Very positive experience and such resonance with your stories and sharing. You really made me feel comfortable being myself and thoroughly accepted and ‘met’ in the dialogue. And so - the me I know myself to be when I’m truly comfortable to be myself and not trying to ensure I don’t take ’too much focus’ showed up. Thank you so much Jess. What a different experience than most people describe receiving a ‘diagnosis’ (inappropriate term as it is for this). It was a very healing experience in itself.” Helen, Psychotherapist


“Just a note to thank you and the team again for the amazing work. Jess's report and our conversation was truly a life-changing moment for me that I am so grateful I've had.”


“I just want to say thank you to Jess for taking me through my assessment gently and for the wisdom shared and validation I felt.”


The assessment experience was great, although I am still taking it in. I found the conversation (and ultimately my diagnosis) helpful, valuable and validating. Jess was so knowledgeable, great at putting me at ease and explaining things - I really felt I was in good hands.”


"Thanks to Jess as I have found this process extremely helpful. It has helped me to make sense of so much and I am so glad that I took the step.”


“Thank you very much to Jess for making me feel so at ease and heard during the assessment. I felt very anxious at the outset and Jess made it a helpful, positive and enlightening experience. I feel like it was a very first positive step in the journey ahead to understand myself and create better coping strategies.


"It's been an overwhelming journey, but I've found the experience so validating. I feel like I now have a good starting point from which I can begin to understand how my brain works - and I know there will be a significant positive impact on my life as a result. I am so glad I took this step and immensely grateful for your time, the report and the resources."


"It was a very good, worthwhile and beneficial call, thank you for all your support and encouragement. It’s a whole new world, exciting, daunting, overwhelming but overall a great step into a new chapter for me, thank you! You clocked it all so well in the report and whilst I didn’t know if to laugh or cry or love it or hate it, I definitely do love it and embrace it all. New chapter, with new horizons and new ‘tools’ to manage life. This has been a fantastic experience and a lot for me to now grasp and learn, and definitely going to look into all the recommended resources."
