What Is WCAG Accessibility Compliance for a CMS?
IntermediateQuick Answer
TL;DR
WCAG (Web Content Accessibility Guidelines) compliance for a CMS means both the CMS editing interface and the content it produces meet accessibility standards for people with disabilities. WCAG 2.1 Level AA is the most commonly required standard, covering perceivable content (alt text, captions, color contrast), operable interfaces (keyboard navigation, no time limits), understandable content (clear language, predictable behavior), and robust markup (valid HTML, ARIA labels). Many jurisdictions legally require WCAG compliance for public-facing websites.
Key Takeaways
- WCAG compliance applies to two things: the CMS admin interface (for editors with disabilities) and the published content (for visitors with disabilities)
- WCAG 2.1 Level AA is the standard most organizations target—it's required by the EU's European Accessibility Act and referenced by the US ADA
- CMS features that support accessibility: alt text fields, heading hierarchy enforcement, color contrast checking, and semantic HTML output
- The CMS can enforce accessibility at the content creation stage—requiring alt text before publishing, for example
- Automated testing catches ~30% of accessibility issues; manual testing and screen reader testing are essential
