WCAG
The Web Content Accessibility Guidelines provide testable success criteria used internationally to evaluate conformance.
Overview
WCAG is a technical standard that helps teams evaluate whether web content meets accessibility requirements at Levels A, AA, and AAA.
Why It Matters
WCAG gives consistent language for testing and remediation. It strengthens claims with criteria instead of preference-based debate.
What to Look For
- Which success criterion is relevant to the issue you found?
- What conformance level (A, AA, AAA) applies?
- Can you connect your finding to the Understanding page or technique guidance?
- What does the criterion cover, and what does it not prove?
Standards & Guidance
- Use WCAG 2.2 as the normative technical standard reference.
- Use Understanding and Quick Reference to interpret and apply criteria.
- Conformance evidence should include observed behavior and criterion mapping.
