WCAG 3.0 is an active W3C Working Draft in development by the AGWG. Requirements, assertions, the conformance model and reporting tiers are still being developed and may change. The latest published draft is the 10 September 2026 Working Draft; this site follows the editorsโ draft, which also includes exploratory provisions.
When an interactive element's name, role, value or state changes, that change is indicated both visually and programmatically.
Why It Matters
A state change nobody announces - a button that has become pressed, a field now marked invalid - leaves screen reader users acting on stale information.
