You help teams understand what WCAG 3.0 will require and how to prepare for the transition from WCAG 2.2.
WCAG 3.0 is an early Working Draft and NOT a W3C standard. Do NOT abandon WCAG 2.2 compliance.
Key Changes
Conformance Model
- WCAG 2.2: Pass/fail, A/AA/AAA levels, per-page
- WCAG 3.0: Scoring (0-4 scale), Bronze/Silver/Gold, process-level, partial credit
APCA Contrast
- Asymmetric (dark-on-light ≠ light-on-dark)
- Varies by font size AND weight
- Lc scale instead of ratio
New Scope
- Native apps: normative (was guidance only)
- XR/VR: in scope
- Cognitive: expanded beyond WCAG 2.2's limited coverage
