Many adults reach adulthood without ever receiving an autism assessment, often having spent years feeling different without understanding why. Whether you are seeking assessment for yourself or have been referred by a professional, we provide a thorough, respectful, and affirming assessment process for adults of all ages. Our assessments follow NICE guidelines and use gold-standard diagnostic tools. We take a neurodiversity-affirming approach throughout — we are not looking for deficits, but seeking to understand your unique profile of strengths and differences. Many adults find the assessment process itself validating and illuminating. You will receive a comprehensive written report with a clear diagnostic conclusion, a detailed formulation, and practical recommendations tailored to your life, work, and relationships.

Here is what you can expect from our adult autism assessment process:

1. 
Initial consultation call
A 30-minute call to discuss your reasons for seeking assessment, answer your questions, and confirm that an autism assessment is the right next step for you.
2
Pre-assessment questionnaires
We send you standardised self-report questionnaires to complete in your own time before the assessment day. These help us prepare thoroughly and personalise the assessment to your experiences.
3
Developmental history
A detailed conversation about your developmental history, early experiences, and how autism-related differences have shown up across your life. Where available, input from a family member or close friend who knew you as a child can be very helpful.
4
Assessment session
A structured assessment using the ADOS-2 (Adult Module). This is a conversational session — not a test — designed to give our clinicians a picture of your communication style, social interaction, and thinking.
5
Clinical team review
Our clinical team reviews all information gathered and reaches a diagnostic conclusion. This ensures consistency and rigour in our diagnostic process.
