The National Autism Assessment Centre (NAAC)
Diagnostic Autism (ASD) Assessments for Children and Adults
Autism and Diagnostic Assessments
The NAAC provides a private comprehensive needs-led autism diagnostic service. The Autism Diagnostic Assessment service provides bespoke person-centred and positive support throughout the process.
Autism and Neurodiversity Screening Assessment
The NAAC provides specialist neurodevelopmental screening with recommendations to your GP for further assessment and signposting to resources for help and support. We are also able to undertake observations in nurseries, schools and colleges and provide a report with our recommendations for support.
Neurodiversity Insight – Pre-Diagnostic Screening Across England
Wondering if your child is neurodiverse and not sure where to go next?
If you feel your child is presenting differently at school and you may suspect ADHD or autism and feel unsure what to do next, you’re not alone. Waiting lists are long, private assessments can be expensive, and it’s hard to know where to start. That’s why we created Neurodiversity Insight — a trusted pre-diagnostic neurodiverse screening and guidance service for families and individuals across England.
Structured Screening Tools
We use gold-standard questionnaires like the Vanderbilt ADHD Diagnostic Rating Scales (VADRS) AQ-10, Dyslexia Checklists and SDQ to explore neurodiverse presentations in children, teens, or adults.
What You’ll Get
1:1 Consultation
You will be able to talk to a neurodiverse specialist who listens. We guide you through your history, concerns, and goals in a safe, non-judgmental setting.
Summary Report
You’ll receive a clear written report outlining patterns, concerns, and recommended next steps — useful for schools, GPs, or EHCP planning.
Follow-Up Advice
We help you understand your report and what to do next — from GP referrals to school support or pursuing a full diagnostic assessment.
Attend a meeting with the SENCO and parent and advise with implementation of recommendations
Attend a 1 hour meeting with the SENCO and parent to discuss and agree implementation of recommendations.
Advise in Transition plans in school
Offer 1 hour training to support wider school understanding of child’s neurodiverse presentation and support plan.
Is the screening a diagnosis?
No — and that’s the point.
This is a screening and support service, ideal for those unsure if they want or need a full diagnosis. It’s designed to inform, not to label and to facilitate appropriate reasonable adjustments in school or education that supports effective learning, inclusion and positive identity formation.
Who Is the Neurodiversity Insight screening For?
Families on long NHS waiting lists
Parents exploring autism for the first time
Adults wondering about autism later in life
Schools seeking structured evidence for SEN support

OUR APPROACH
The National Autism Assessment Centre (NAAC)
is a specialist screening, assessment, training and support service for:
Children or adults with a query of having one or more of the following neurodiverse conditions:
A D D Dyslexia Dyspraxia Autism (ASD) Dyscalculia
The Centre also provides a wide range of specialist support services in behavioural/medical assessments for children and adults who already have an autism diagnosis.
Autism “Experts by Experience”
We work with experts by experience to inform all of our screening, assessments, training and post-diagnostic support.
Negative diagnosis as an outcome
If you are not diagnosed as autistic after our screening and assessment process, we will still provide you with 1:1 feedback and signposting.
It is possible that if you are a girl or woman, you may have masked the signs of autism and this will make it more difficult for autism to be diagnosed.
An absence of a diagnosis does not prevent us from supporting you or signposting you to more helpful resources.
Are you already diagnosed as Autistic or Neurodiverse?
If you already have a diagnosis of autism or a neurodevelopmental condition, we can provide you with support in the following areas:
Help with benefits, including Personal Independence Payments (PIP)
Reasonable adjustments at school, college or work
Bespoke co-education sessions for family members or work colleagues who can support you better
Personalised autism support – development of schedules, routines and practical strategies to improve your quality of life
Completion of Autism Health and Care Passport
Further medical/holistic specialist assessments and liaison with your GP
Behavioural assessments
Positive Behavioural Support strategies
