Web accessibility: guides, RGAA 5, WCAG 2.2 and best practices

Updated

A11y Resources is an independent bilingual resource for building accessible websites: RGAA 4.1.2 in force, preparing for RGAA 5 (publication announced for end of 2026), WCAG 2.2, ARIA, testing and tools.

The essentials in 30 seconds

Where do we stand: RGAA 4.1.2, WCAG 2.2 and RGAA 5?

Three texts overlap. RGAA 4.1.2 is the French verification method required today. WCAG 2.2, a W3C Recommendation since 5 October 2023, is already stable. RGAA 5 will take over most of it.

The four POUR principles of WCAG

Every accessibility requirement belongs to one of these four principles. Full detail in the fundamentals guide.

Perceivable
Transcripts, text alternatives, sufficient contrast, clear visual organisation.
Operable
Keyboard navigation, logical tab order, skip links, large enough touch targets.
Understandable
Declared language, consistent behaviour, simple instructions, cognitive accessibility.
Robust
Compatibility with assistive technologies, correct ARIA, valid code.

Frequently asked questions

Which RGAA version applies in 2026?

RGAA 4.1.2 remains in force until RGAA 5 is published, announced for the end of 2026. DINUM asks that no accessibility work be suspended.

Will my RGAA 4.1.2 audit remain valid?

For a limited time: per DINUM, statements established on RGAA 4.1.2 stay valid 18 months after RGAA 5 is published, within three years of their own publication date.

What is the difference between RGAA, WCAG and EN 301 549?

WCAG is the W3C’s international standard. EN 301 549 is the European standard that incorporates its requirements. RGAA is the French verification method, broken into criteria and tests.

Should I wait for RGAA 5 to apply WCAG 2.2?

No. WCAG 2.2 has been published since October 2023 and its six level A and AA criteria should not change in substance. Adopting them now avoids rework in 2027.
