The Accessibility Debt Trap: Why “Compliant” EdTech Keeps Getting Rejected by UK Schools

On paper, many digital learning platforms look ready for UK schools. Accessibility audits are signed off. WCAG checklists are complete. Statements are published. And yet procurement stalls. Pilots fail. Schools walk away.

The problem is not that publishers are ignoring accessibility. It is that accessibility testing has quietly drifted away from how pupils with access needs, and the teachers who support them, actually use technology in classrooms. What passes an audit increasingly fails under real conditions, with real assistive technology and real-time pressure.

That gap is now shaping buying decisions.

The Audit Illusion: How WCAG Became a False Finish Line

WCAG remains the backbone of accessibility regulation in the UK. But in practice, it was never designed to validate classroom usability on its own.

The Department for Education (DfE) is explicit that meeting standards requires more than documentation. Its digital accessibility guidance states that hardware and software should support the use of accessibility features, highlighting an expectation that platforms work with assistive tools in real environments, not just in controlled audit scenarios.

This distinction matters because most audits focus on code-level compliance rather than live interaction. Automated checks flag missing labels, colour contrast issues, or keyboard traps. They do not reveal whether:

• A screen reader workflow collapses mid-lesson
• Speech-to-text lags during assessments
• Focus order breaks when content is dynamically loaded
• AAC devices integrate reliably with lesson navigation

Passing WCAG criteria does not guarantee a pupil can complete a task independently. That is where the disconnect begins.

Why Automation Misses What Schools Actually Experience

Automated tools are useful, but limited. They typically surface a fraction of accessibility issues and none of the contextual ones.

The DfE’s own guidance on accessibility audits acknowledges this limitation, explaining that audits identify barrier types and remediation techniques, but do not validate outcomes. In effect, they initiate fixes rather than confirm success.

This is how publishers fall into an accessibility debt loop:

• Audit identifies issues
• Fixes are implemented against WCAG success criteria
• The platform is released without real user validation
• Schools uncover failures during pilots or rollout
• Emergency remediation begins
• The cycle repeats

Each loop costs time, credibility, and often entire contracts.

The Classroom Reality WCAG Cannot Simulate

UK schools operate in a far messier environment than test labs. The DfE requires that school software be compatible with assistive technology and audio-visual equipment, explicitly linking accessibility to interoperability.

That requirement exposes the blind spot in many accessibility programmes. A platform may technically support keyboard navigation, but fail when:

• Used alongside classroom display systems
• Accessed on managed devices with restricted permissions
• Combined with older assistive hardware still common in schools

These failures only emerge through assistive technology testing carried out in conditions that mirror real classroom use.

Why Real Users Changed the Procurement Conversation

The DfE has been unambiguous about one thing: audits are not a substitute for user testing.

Its inclusive research guidance states that while accessibility testing may validate WCAG compliance and some assistive technology behaviour, it will not test contextual use and should not be treated as an alternative to testing with real users with access needs.

This has filtered directly into procurement expectations.

Increasingly, schools and multi-academy trusts are asking not just whether a platform is compliant, but how that compliance was validated. Evidence of real user testing for accessibility is becoming a differentiator, particularly where platforms are expected to meet evolving school accessibility requirements during procurement, especially for services supporting SEND learners.

A Failure Scenario Publishers Rarely See Coming

Consider a literacy platform that passes an audit with minor issues resolved.

During a school pilot, pupils using AAC devices struggle to navigate between exercises. Screen reader announcements overlap with audio instructions. Teachers report that lessons take longer to deliver, not shorter.

The platform technically complies. Practically, it disrupts teaching.

This is not purely hypothetical. A government SEND assistive technology pilot found that awareness and adoption of tools such as AAC devices remain limited across schools. That limited familiarity changes expectations. When AAC is present, schools cannot absorb trial-and-error. They expect suppliers to demonstrate that assistive technology works in real classroom conditions, not that it might work after remediation.

When usability breaks, schools do not ask for a remediation roadmap. They remove the product.

The Scale of Remediation Debt Across the Public Sector

Accessibility debt is not isolated to education, but education feels its impact fastest.

Accessibility Debt Is Not Just an Education Problem

Accessibility debt extends across the UK public sector, not just education. The Government Digital Service’s Accessibility Monitoring of Public Sector Websites and Mobile Apps 2022 to 2024 report shows the scale of unresolved issues in practice.

Between January 2022 and September 2024, GDS tested 1,203 public sector websites and 21 mobile apps under the Public Sector Bodies (Websites and Mobile Applications) Accessibility Regulations. Across these services, 29,787 accessibility issues were identified, and just 55.3% of those were fixed during the monitoring period. Notably, 3,693 issues remained unfixed at re-test, a clear example of ongoing remediation cycles rather than resolution.

What this demonstrates is not a lack of effort, but a pattern: compliance checks do not guarantee resolution. Even under active monitoring, accessibility debt continues to accumulate.

Why Schools Have Become Less Tolerant of “Fix-It-Later” Platforms

Schools operate inside this same public-sector environment, but with far less room for iteration. When accessibility failures surface in classrooms, they directly affect teaching time, pupil independence, and statutory obligations.

Reports from disability advocacy groups show that many schools already struggle to meet their legal duties around accessibility planning. As scrutiny increases, tolerance decreases. Platforms that introduce friction, even temporarily, are treated as risk rather than opportunity.

In practice, this means suppliers are no longer judged on intent or remediation promises. They are assessed on whether accessibility works immediately, reliably, and under real classroom conditions. Platforms that add uncertainty are quietly excluded.

How Publishers Break the Remediation Loop Without Rebuilding Platforms

For publishers serving higher education, accessibility debt rarely comes from neglect. It builds when fixes are applied in isolation, validated against audits, but not against real assistive technology behaviour. Over time, each release inherits risk from the last, making accessibility harder to stabilise rather than easier to maintain.

This is where Magic EdTech fits into the delivery model. Working within publishers’ existing platforms, Magic EdTech supports WCAG-aligned remediation for assessment and learning environments, including WCAG 2.2 requirements, while validating changes through real-world use of assistive technology. Where recurring issues surface, teams also help publishers establish analytics that expose accessibility risk earlier, reducing rework rather than reacting to it.

WCAG vs Usability: The Distinction Publishers Can No Longer Ignore

The tension between WCAG vs usability in EdTech is now central to buying decisions.

WCAG answers: Does the platform meet technical success criteria?
Schools ask: Can our pupils actually use it, independently, in class?

Bridging that gap requires a shift in testing philosophy:

Publishers that stay on the left side of this table will keep reworking the same issues.

Where Accessibility Testing Has to Go Next

Accessibility maturity in UK EdTech is moving from compliance proof to operational proof.

That means testing that:

• Involves users of screen readers, switch devices, AAC tools, and magnification software
• Covers real classroom workflows, not isolated components
• Validates assistive technology compatibility across updates
• Feeds findings directly into product and QA pipelines

This is not an expansion of scope for its own sake. It is a response to how schools now assess risk.

Breaking the Rework Cycle Without Slowing Delivery

The publishers who escape accessibility debt are not doing more audits. They are doing fewer, better-targeted ones, supported by real-world validation.

This is where specialist remediation partners make a difference. Teams that combine structured audits with disabled-user testing reduce rework because issues are validated before release, not rediscovered during procurement.

Magic EdTech’s accessibility remediation approach reflects this shift. By aligning WCAG compliance with classroom-ready usability testing, including assistive technology workflows, publishers gain evidence that schools recognise, not just reports that regulators accept.

Accessibility That Survives the Classroom

The real test of accessibility is no longer whether a platform passes an audit. It is whether it survives a school day.

For UK publishers, that distinction defines the difference between steady adoption and endless remediation. Accessibility that works only on paper creates debt. Accessibility that works with pupils clarifies it. And schools are watching closely.
