TL;DR — WCAG 3 shifts accessibility from binary pass/fail to a scored model (Bronze/Silver/Gold) with outcomes measured at the user level, not the element level. Here’s what has changed, what the new scoring means for your product, and a concrete 20-item checklist for shipping against it.
What’s different in WCAG 3
The old model — WCAG 2 — evaluated individual success criteria against individual components. The new model evaluates user outcomes across journeys. “Can a screen-reader user complete the checkout?” not “Does every button have an aria-label?” That reframing is the whole point.
The scoring system
Bronze
The floor. Roughly equivalent to WCAG 2.1 AA. No product should ship below this. Most regulatory frameworks (EU, US Section 508) reference Bronze as the minimum.
Silver
Good practice. Adds outcome-based testing — actual users completing actual tasks — rather than just automated checks.
Gold
Aspirational. Continuously audited, user-research-validated, covers cognitive and linguistic accessibility in addition to perceptual.
The 2026 accessibility checklist
If you hit these 20, you are in Silver territory for most products:
- 1. All interactive elements keyboard-reachable, in logical tab order.
- 2. Visible focus indicator, 3:1 contrast minimum against adjacent content.
- 3. All images have meaningful alt text; decorative images are empty-alt.
- 4. Color is never the only signal carrier.
- 5. Text contrast 4.5:1 for body, 3:1 for 24px+.
- 6. `prefers-reduced-motion` respected — every animation has a reduced variant.
- 7. `prefers-contrast: more` respected with a high-contrast theme.
- 8. Form fields have associated labels (not placeholders as labels).
- 9. Error messages are programmatically associated and actionable.
- 10. Modals trap focus correctly; ESC closes them.
- 11. Screen-reader order matches visual order.
- 12. Live regions announce important updates (loading, errors).
- 13. Buttons vs. links — not interchangeable; buttons do, links go.
- 14. Tables have headers; complex tables have scope and caption.
- 15. Video has captions; audio has transcripts.
- 16. Touch targets minimum 44×44px.
- 17. Session timeout is warned, with an easy extension.
- 18. Text resizes to 200% without breaking layout.
- 19. Single-letter keyboard shortcuts are either off by default or remappable.
- 20. Non-decorative AI-generated content is labeled as such.
Frequently asked questions
Is WCAG 2.1 AA still valid in 2026?
Yes. WCAG 3 is the new standard, but 2.1 AA remains the legally-enforced minimum in most jurisdictions and is equivalent to WCAG 3 Bronze.
Do I need an accessibility specialist to hit Silver?
For a complex product, yes — at least part-time. Automated tools catch ~30% of issues; the rest require domain expertise.
How do I prioritize accessibility fixes?
Fix keyboard-navigation blockers first — they’re the highest-impact. Then contrast and focus visibility. Then screen-reader semantics. Cosmetic polish last.
