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.

Submission Status Notified
Group: error-handling • Guideline: prevent-errors
Summary in Plain English
When a submission succeeds or fails, the interface says so at the time it happens.
Why It Matters
Without an announcement, a screen reader user has no way to know whether anything happened, and may submit again - or leave believing a task is done when it failed.
