The UK's first neurodiversity-led design standards body
The Neurodiversity Design Council assesses software, digital services and content against a published standard for neurodiversity-inclusive design, then awards certification that anyone can check. Every assessor is neurodivergent.

A product can pass every accessibility checklist and still exhaust the people using it
The screens are cluttered, the navigation changes shape from page to page, the text arrives in long unbroken walls and nothing can be adjusted. None of that fails WCAG, yet all of it wears neurodivergent people down.
Checklists catch the obvious problems and lived experience catches the rest, which is why every NDC assessor is neurodivergent and why each assessment pairs that experience with professional technical testing.

What we do
Publish the standard
We develop and maintain the Neurodiversity Design Standard, a documented and versioned assessment framework that sits alongside WCAG 2.2 and BS 8878. It's publicly available and reviewed by our neurodivergent advisory panel.
Assess products against it
We assess products across all seven domains. Every assessment is carried out by neurodivergent assessors who also hold professional technical testing skills, and every one ends in a structured written report with scores, evidence and remediation guidance your development team can act on.
Award certification
Products that meet the thresholds receive NDC certification at one of three tiers. Badges are hosted on our systems so they can be verified, expired or revoked, and there's no such thing as a self-declared NDC badge.
Three tiers of certification
Certification is based on evidence and runs for a fixed period. If a complaint or tribunal ever comes, documented evidence that you made proactive reasonable adjustments carries real weight.

How certification and the hosted badge work
NDC-2026-001, the Neurodiversity Design Standard
Seven domains cover the whole of a neurodivergent person's experience of a product. Each domain holds five criteria, and each criterion is scored from 0 to 4.
- D1Cognitive load and information architectureHow much mental effort the product demands and how well its information is organised.5 criteria, 20 points
- D2Reading and language accessibilityWhether content is legible and understandable for people with dyslexia, ADHD or processing differences.5 criteria, 20 points
- D3Sensory designHow the product handles visual, auditory and motion elements for sensory-sensitive people.5 criteria, 20 points
- D4Predictability and consistencyWhether the product behaves reliably and builds confidence through consistent patterns.5 criteria, 20 points
- D5Executive function supportHow well the product supports planning and finishing tasks for people with executive function differences.5 criteria, 20 points
- D6Emotional safety and trustWhether the product respects wellbeing, avoids manipulation and earns trust.5 criteria, 20 points
- D7Flexibility and personalisationWhether people can adapt the product to their own needs and assistive technology.5 criteria, 20 points
- Total35 criteria, 140 points
How assessment works
The process is the same for every client, and we agree the cost with you before any work starts.
Scope and agree
You tell us what you'd like assessed. We agree the scope, platforms, features and timeline, so you know the cost and the process before we begin.
Assessment
Our neurodivergent assessors review the product against all 35 criteria, and every score is backed by specific evidence and observations.
Report
You receive your overall score, a breakdown by domain, a prioritised issue register and a recommendations roadmap written to be handed straight to your development team.
Certification
Products that meet a threshold receive their hosted badge straight away. Products below it get a clear route to the next tier.
Reports written for the people who fix things
An NDC report has to work for the whole team, including the people who never saw the brief.
For your development team
Every issue comes with a plain description of what's wrong, why it matters to neurodivergent users and how to fix it. Recommendations are ranked by severity and written as concrete steps a team can put into a sprint.
For product and UX teams
Scoring by domain shows exactly where the product is strong and where it falls short, and the roadmap maps onto your backlog. Positive practice highlights show what you already do well, so you know what to protect as well as what to change.
For compliance and leadership
A two-page executive summary for board reporting, plus documented evidence of proactive reasonable adjustments for Equality Act, European Accessibility Act and PSBAR obligations. The report follows the shape an accessibility statement needs, and certification can be cited in procurement responses, G-Cloud service definitions and RFQ submissions.
If neurodivergent people use it, we can assess it
The standard applies to any digital product, service or piece of content that neurodivergent people use, from a council's planning portal to a staff onboarding pack.



We group assessments into six sectors.
Software and platforms
SaaS products, web applications, mobile apps, internal tools, HR and payroll systems, project management platforms, CRM software and design system components.
For example, a project management tool where task views, notifications and navigation are assessed for cognitive load, sensory overwhelm and executive function support.
Learning and education
LMS platforms, e-learning courses, course authoring tools, educational apps, online training, assessment and quiz systems and virtual classrooms.
For example, an LMS where content layout, predictable navigation, timed assessments and reading accessibility are assessed across the whole learner journey.
Websites and digital services
Public websites, e-commerce platforms, booking systems, customer portals, intranets, membership sites and help centres.
For example, an online shop where the checkout, error handling, decision complexity and time pressure are assessed for the points where neurodivergent shoppers get stuck.
Public sector and government
Council websites, NHS digital services, government portals, citizen-facing tools, benefits systems, intranets, extranets and public consultation platforms.
Under the Public Sector Bodies Accessibility Regulations 2018 you must meet WCAG 2.2 AA and publish an accessibility statement, and you stay legally responsible when a supplier runs the website for you. A government study found that 4 in 10 council homepages failed basic accessibility tests. An NDC assessment gives your statement the neurodiversity evidence it needs.
For example, a council planning portal where form complexity, clarity of language, save and resume and the wording of errors are all assessed.
Financial services
Banking apps, insurance portals, investment platforms, payment systems, fintech products, pension dashboards and mortgage applications.
For example, a banking app where transaction clarity, notification volume, the absence of dark patterns and information density are assessed for neurodivergent customers.
Content and communications
PDFs, digital documents, onboarding materials, help documentation, video, marketing materials, email templates, policy documents and accessibility statements.
For example, an employee onboarding pack where plain language, structure, reading flow and the choice of alternative formats are assessed.

What an NDC assessment finds in practice
The three excerpts below are illustrative. They show the format and level of detail clients receive, based on patterns we see across digital products, and none of them is a real client assessment.
Illustrative report excerpt, learning and education
Learning management system
What we found
- Good scores for visual accessibility (WCAG compliant, strong contrast, keyboard navigable) but poor scores in three NDC domains
- Course content delivered in long unbroken blocks of text with no summaries or signposts
- Timed quizzes with no way to pause or extend, which created artificial time pressure
- A navigation structure that changed between modules, so learners had to relearn the interface every time
- Twelve to fifteen notifications a day with no way to reduce or control them
Outcome
- NDC Reviewed, below the Endorsed threshold
- Three quick wins identified: content summaries, untimed quizzes by default and notification controls
- Those changes alone would lift the score to Endorsed within a single development sprint
Illustrative report excerpt, financial services
Banking mobile app
What we found
- Strong in most domains, with consistent navigation, clear language and a clean interface
- Tested on iOS with VoiceOver and Android with TalkBack as well as on desktop
- Confirming a transaction meant reading and checking a 16-digit reference in your head, with no way to copy or compare it
- Marketing push notifications switched on by default, with the opt-out three levels deep in settings
- Spending insights that told categories apart by colour alone, with no labels or patterns
Outcome
- NDC Endorsed (Level 2)
- The buried notification opt-out flagged as a critical dark pattern
- Once that's fixed, the app would be on course for Certified at its next annual assessment
Illustrative report excerpt, public sector
Council planning portal
What we found
- Residents asked to complete a 23-field form on a single page with no save and resume
- Mandatory fields marked by colour alone, a red asterisk with no label
- Error messages at the top of the page, so people had to scroll up, find the error, scroll back down and remember what to fix
- Planning jargon throughout, with no glossary and no plain English alternative
Outcome
- NDC Reviewed, well below the Endorsed threshold
- Form structure, error handling and clarity of language identified as the highest-impact areas
- A three-phase plan: break the form into steps with progress shown and save and resume, then move errors next to their fields and drop colour-only markers, then rewrite in plain English with a glossary

Questions people ask
Who can apply for an NDC assessment?
Any organisation that builds or provides software, digital services, websites, mobile apps, e-learning content or other digital products. We assess the product rather than the organisation, and there's no minimum company size.
How long does an assessment take?
A standard assessment usually takes two to three weeks from start to report. Larger or more complex products take longer, and we agree the timeline with you before we begin.
What if we don't pass?
Every assessment produces a detailed report whatever the score. If your product doesn't reach Endorsed or Certified, you receive Reviewed status and a roadmap showing what to fix and how far each change would raise your score. Most organisations reach a higher tier within one development cycle.
How is the NDC different from WCAG compliance?
WCAG concentrates on visual, auditory and motor accessibility. The NDC standard assesses cognitive load, executive function support, sensory design, emotional safety and flexibility for neurodivergent users, which is why a product can be fully WCAG compliant and still be unusable for someone with ADHD or autism.
Are the assessors really all neurodivergent?
Yes. Every assessor has lived experience of one or more neurodivergent conditions, including ADHD, autism, dyslexia, dyspraxia, dyscalculia and sensory processing differences. That experience is the foundation of the whole approach, because it picks up what checklists miss.
How does the badge work?
NDC badges are hosted on our servers and placed on your site with a short code snippet. If your certification expires or is revoked, the badge disappears by itself, and anyone can check a badge on the Verify page.
Does the NDC standard have legal standing?
The standard is a published, versioned assessment framework. It doesn't replace the Equality Act or the European Accessibility Act, but it gives you structured, evidenced documentation that your organisation has taken proactive steps for neurodivergent users, and in a complaint or tribunal that evidence of reasonable adjustments carries real weight.
How much does it cost?
It depends on the scope and complexity of the product. The pricing page has the detail, and founding clients receive a reduced rate.
Do we still need a separate WCAG audit?
Yes. The NDC standard works alongside WCAG. WCAG 2.2 covers visual, auditory and motor accessibility, while the NDC standard covers the cognitive, sensory and executive function ground WCAG reaches only lightly, so a product should meet both. If you already have a WCAG audit, our assessment adds the neurodiversity layer on top, and if you don't, we can recommend partners.
Does an NDC assessment help with accessibility statement obligations?
Yes. Public sector organisations must publish an accessibility statement under the Public Sector Bodies Accessibility Regulations 2018, and an NDC assessment gives you documented, evidenced findings for the neurodiversity-inclusive design section. Your report and certification status can be cited as evidence of proactive steps for neurodivergent users.
Can NDC certification be specified in procurement?
Yes. Government guidance recommends making accessibility standards part of your request for quotation and part of contract evaluation. NDC certification can be specified alongside WCAG 2.2 AA, which holds suppliers to account for the neurodivergent user experience as well as for technical accessibility.
We supply government. Does the NDC help with procurement evidence?
Yes. Government procurement guidance asks suppliers to evidence accessibility compliance, referencing EN 301 549 and third-party audits. NDC certification is independent, evidenced proof that your product has been assessed for neurodiversity-inclusive design, and it can go into G-Cloud service definitions, Digital Marketplace listings, RFQ responses and any submission that asks for accessibility evidence, alongside your WCAG audit.
What happens when GDS monitors our site?
The Government Digital Service monitors public sector websites with automated checks (axe), keyboard testing, 400% zoom and assistive technology, and if it finds issues you usually get a 12-week window to fix them. That monitoring covers WCAG and leaves neurodivergent usability untested, so an NDC assessment on file shows you've gone past the minimum on the cognitive, sensory and executive function side.
Our website is run by a supplier. Who is responsible?
You are. Government guidance is clear that you're legally responsible for your website meeting accessibility requirements even when a supplier runs it. An NDC assessment can form part of holding that supplier to account: you can ask the supplier to submit the product, make NDC certification a contract requirement or commission an assessment yourself to check what was delivered.
Can we claim disproportionate burden for neurodiversity?
The disproportionate burden defence lets an organisation argue that meeting a requirement would cost too much for the benefit. Government guidance is explicit that lack of time or knowledge doesn't count, and nor does never having made it a priority. Many neurodiversity-inclusive fixes are cheap (chunking content, adding save and resume, adjusting notifications, rewriting error messages) and help a large group of people, and because an NDC assessment names each fix and the effort it takes, a disproportionate burden argument becomes hard to sustain for most of what it finds.
