Neurodiversity Insight – Pre-Diagnostic Screening Across England

Neurodiversity Insight Screening Pathways

Are you concerned about your child’s development? Worried about their lack of communication or their behaviour?

Neurodiversity Insight Screening can give you an early understanding about your child from as young as 2 years old. It will give you clear direction and practical support.

At the National Autism Assessment Centre, we understand that every child develops in their own way  and that early understanding of their needs can make all the difference. We have two Neurodiversity Insight Screening Pathways which are designed to give parents and professionals clear, evidence-based insights into a child’s development, behaviour and sensory world, helping you take the right next steps with confidence.

Each screening pathway includes: 

  • A comprehensive evidence-based screening process

  • A clear and accessible report

  • A Post Screen Action Plan (PSAP) built around the SPELL Framework (Structure, Positive approaches and expectations, Empathy, Low arousal, Links)

  • A Positive Behavioural Support (PBS) plan to guide daily strategies at home and school

  • A complimentary consultation with your child’s SENCO or early years lead to translate the findings into practical support

All of this is available for a single fee of £300.

Pathway 1 – Screening for Autism for your non-verbal child (NI-Autism)

For children aged from 2 years who are not yet using language. This pathway is designed for younger children whose parents or early years practitioners have concerns about social communication, sensory differences or early behaviour patterns that may indicate autism.

 We understand that at this stage, children often relate to the world through their senses and use behaviour as communication. Our NI-Autism screen focuses on understanding what your child’s behaviour means not just what it looks like.

 Our assessment includes:

  • Direct observation of your child’s social interaction, play, and sensory responses

  • The M-CHAT-R/F , Autism Observation Checklist or SCT screening tool for autism indicators

  • A Sensory Profile and analysis to understand how your child experiences the world

  • A Behavioural Analysis grounded in Positive Behavioural Support principles

You’ll receive a comprehensive report and a Post Screen Action Plan (PSAP) with practical strategies for home and nursery, developed using the SPELL framework and PBS principles.

(we will travel to you, but ask that you cover milage at 0.45 pence a mile from our base in Derbyshire. This is in addition to the sceening and professional report fee of £300.

Pathway 2 - Neurodiversity Insight Screen for ADHD and Autism (NI-ADHD+Autism)

For children aged 5+ who have language and attend a mainstream school. This pathway supports families and schools concerned about attention, focus, hyperactivity, impulsivity, or behavioural challenges that may suggest ADHD or related neurodevelopmental differences.

 We recognise that your child will often present with complex profiles, which is why we use a wide range of screening tools to understand strengths and difficulties across learning, communication and emotional regulation.

Our assessment includes:

  • The Vanderbilt ADHD Diagnostic Rating Scale

  • The Strengths and Difficulties Questionnaire (SDQ)

  • A detailed Behavioural Analysis

  • Screening for co-occurring traits of Autism, DCD (Dyspraxia) and other neurodevelopmental conditions using structured history and observation

 You’ll receive a clear written report with tailored recommendations, a Post Screen Action Plan (PSAP) for home and school, and a Positive Behavioural Support (PBS) plan to help understand and manage behaviours effectively.

Pathway 2 Neurodiversity screening can be undertaken on-line.

Your Next Step: Insight, Not Labels

 Our screening pathways are not diagnostic assessments, but they provide powerful insight into your child’s developmental profile, guiding you to know if you should seek further assessment or adapt support immediately.

 Each screening includes a complimentary follow-up meeting with your child’s SENCO or early years lead, ensuring findings are used meaningfully to enhance your child’s learning and wellbeing.

Fee: £300 (inclusive of report, PSAP, PBS plan, and SENCO consultation)

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

No — and that’s the point.

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
