WCAG Details
What It Is
Web Content Accessibility Guidelines (WCAG) 2.2 is the W3C's technology-agnostic standard for web accessibility. It provides testable success criteria to make content perceivable, operable, understandable, and robust for people with disabilities. Structured as a layered model with principles, guidelines, and criteria.
Key Components
- Four POUR principles: Perceivable, Operable, Understandable, Robust.
- 13 guidelines and ~90 success criteria at Levels A, AA, AAA.
- Informative techniques, understanding docs, and failures.
- Conformance requires full pages, complete processes, accessibility-supported tech, non-interference.
Why Organizations Use It
Meets legal references (ADA, Section 508, EN 301 549, EAA); reduces litigation risk; expands market reach; improves UX/SEO; enables procurement compliance.
Implementation Overview
Phased program: policy, assessment, remediation via design systems/CI tools, training, audits. Applies to all web content creators globally; no formal certification but VPAT/ACR reports common. Targets AA for enterprises.
