EPUB remediation and audit for Benchmark Education

Benchmark Education required its eBook packages to be fully compliant with WCAG 2.2 AA. The digital books had to perform seamlessly across assistive technologies and platforms: screen readers, mobile apps and educational ecosystems. The challenge was not just to remediate the content but to future-proof it against platform upgrades while serving multilingual audiences.

• Non-compliant EPUBs lacked alt text, structured navigation and screen-reader compatibility.
• Inconsistent formatting: tables, lists and images were not semantically structured.
• Multi-language complexity: content was required in English, Spanish, German and Chinese.
• Compatibility testing across NVDA, JAWS, VoiceOver and TalkBack.

• Accessibility audit: issue detection on every EPUB file against WCAG 2.2 AA.
• Remediation workflow: semantic errors in the HTML structure fixed, contextual alt text added, reading orders corrected and markup made consistent.
• Multi-platform testing: performance validated across assistive technologies and devices.
• Multilingual output: content created and validated in four languages.

• 100% accessibility compliance: passed rigorous validation checks across all platforms.
• Multilingual reach: global usability and inclusivity.
• Faster content deployment: the streamlined remediation workflow cut turnaround time by 40%.
• Future-proof standards: compliant with current and evolving guidelines.
