Our Autism assessments
Our Autism assessments are carefully tailored to each individual, offering a fully bespoke and optional face-to-face experience designed to understand your unique profile in depth.
Every assessment is conducted by experienced clinicians, many of whom bring valuable lived experience alongside their professional expertise, creating a more empathetic and informed approach.
We don’t see diagnosis as the end point - ongoing support is a core part of what we offer through our Next Steps program, ensuring you have guidance, resources, and continuity of care after your assessment.
All of our processes follow NICE gold standard guidelines, giving you confidence that your assessment is thorough, evidence-based, and delivered to the highest clinical standards.
What does an Autism assessment involve?
Our thorough and accurate assessments – which take place over 8-10 weeks - involve the following steps:
Step 1 - Fill in registration forms online. You will be sent screener documents after our bespoke triage to make sure you are on the right pathway. Please contact the team with any questions or queries.
Step 2 - Attend an online meeting with one of our friendly practitioners so that they can gather all the relevant information needed to understand your profile.
Step 3 - The ADOS assessment is conducted online or in person, where you will be asked to complete some simple tasks and to discuss your thoughts and experiences.
Step 4 — Our practitioners and psychologist meet to review all the information gathered and decide which diagnosis best suits your presentation.
Step 5 — Receive your full report and a 1-hour feedback session with your practitioner.
Step 6 — Once the final report is ready, you'll have a 1-hour session with a Next Steps support worker to talk through the recommendations and any workplace adjustments. Optional ongoing support is available.

Autism Assessment Pathway
Areas of life a diagnosis can support
Work:
Understanding your own neurodivergent profile will help you be able to advocate for workplace adjustments or support to enable you to thrive at work.
Home
An autism assessment will help identify areas of strength and things that are difficult with regard to home life. This could include managing household chores, childcare, personal care, looking after pets, and much more.
Relationships
The assessment will enable you to better understand your own communication preferences within the context of relationships, and ultimately help to build stronger relationships with loved ones.
What do I do with this diagnosis?
This will be different for everyone, but following the diagnosis, an individual might:
Access strengths-based and specialist support or therapy services.
Share the diagnosis with loved ones.
Speak to work or educational settings about any required reasonable adjustments.
Use it as a gateway to learn more about your own neurodivergent profile.

I had a very positive experience with Autism Services Group from start to finish. I made an enquiry about an ADHD assessment and received a call back to answer any of my questions, I then booked my assessment and was guided through every step by the very helpful staff. Thank you!

I recently had an autism assessment and giving I was really nervous and anxious about the assessment the team were excellent, they put me at ease and the process seemed less daunting, I would highly recommend this service to anyone thinking about going for a private assessment

We have used Autism Services Group for both an adult and child combined assessment of autism and ADHD. We would heartily recommend them. We have found the team responsive, empathetic, clear, concise and simply easy to interact with. The process is quite intense, but the outcomes and recommendations were incredibly helpful. We also feel the team were very balanced, thorough and evidence-based. This really helps reassure us of the quality and gives us confidence in using the recommendations and diagnosis. Thanks again!

From the very beginning, the communication and support from ASG before the appointment were fantastic — the team made everything clear, organised and easy to understand, which really helped put me at ease.
I felt genuinely listened to throughout, and the assessment was carried out with care, empathy and without judgement. The conversations felt relaxed and supportive whilst still being very thorough and informative.

Adult Autism Assessment FAQs
Who can have an adult autism assessment with RTN?
Our adult autism assessments are designed for individuals aged 18 and over who may experience social, communication, or sensory differences, or who suspect they may be autistic. You can self-refer for a private assessment.
Are assessments available online?
Yes. Assessments are delivered online for accessibility and convenience. Private assessments can take place online or in person at our Kent and Cheltenham clinics.
What happens during an autism assessment?
Assessments are led by experienced Neurodevelopmental Assessors using gold-standard diagnostic tools such as the ADOS-2 and ADI-R, alongside a detailed clinical interview. The process is collaborative, person-centred, and designed to help you feel comfortable, understood, and supported at every stage.
Do you understand how autism presents differently across genders?
Yes. Our Neurodevelopmental Assessors receive ongoing training to recognise how autism can present differently across genders, ages, and cultural backgrounds. Many traditional diagnostic tools were developed around male traits, meaning autism in women and girls can sometimes be missed or misunderstood. RTN’s clinicians are trained to look beyond standard checklists to ensure every assessment reflects the individual’s unique presentation.
How soon can I start my assessment?
Once you book a private assessment, your process can begin within 24 hours. We don’t commit to fixed completion timeframes, as progress depends on completing pre-assessment forms and appointments.
What does “adheres to NICE guidelines” mean?
It means our experts follow the standards set out by the National Institute for Health and Care Excellence (NICE) for autism diagnosis in adults. This ensures your assessment meets the same quality and clinical standards used in NHS services.
What support is available after diagnosis?
You’ll receive a detailed report with clear recommendations for next steps, including therapy, workplace support, or community resources. You can also access ongoing help through RTN Therapies, which provides tailored talking therapies and emotional regulation support for autistic adults.
Can I pay for my assessment in installments?
Yes. Flexible payment options are available, allowing you to spread the cost of your assessment.
