WCAG
WCAG stands for Web Content Accessibility Guidelines. The internationally developed guidelines organise requirements under four principles: perceivable, operable, understandable, and robust. Success criteria have conformance levels A, AA, or AAA. A stated WCAG version and target level are required for an unambiguous conformance claim.
Automated checks can find many technical issues but cannot confirm complete WCAG conformance. Manual review, keyboard testing, assistive technology testing, and editorial checks remain necessary. Which WCAG version or legal standard applies depends on the service, organisation, target market, and applicable law and should be assessed for the specific project.
