WCAG 3: what the September 2026 working draft means for designers
The W3C published a new WCAG 3 draft. It is not a standard yet, and WCAG 2.2 AA remains the target, but the direction is worth knowing.
On 10 September 2026 the W3C’s Accessibility Guidelines Working Group published an updated working draft of WCAG 3.0 and invited public review. It follows an earlier draft from March 2026, which was published together with an explainer document.
Still a draft
The W3C’s WCAG 3 introduction describes the guidelines as an incomplete draft that will change and says they are not expected to become a completed standard for a few more years. WCAG 2 will not be deprecated for several years after WCAG 3 is final. AbilityNet’s overview recommends that organisations keep treating WCAG 2.2 AA as the practical standard.
What is different
According to AbilityNet, the name now stands for W3C Accessibility Guidelines and the scope goes beyond web pages to apps, documents, authoring tools and immersive experiences. Instead of a simple pass or fail per page, the draft uses foundational and supplemental requirements and allows graded levels, with the foundational level intended to be roughly equivalent to WCAG 2.2 AA. It also aims to cover more cognitive and language needs.
How to take part
The W3C invites comments by email to its public list or through GitHub. The March 2026 W3C explainer is the best starting point for understanding the proposed structure.
