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 editors’ draft, which also includes exploratory provisions.
developingAssertion
Captions Reviewed By Content Authors
Group: images-and-media • Guideline: captions
Summary in Plain English
An organisational assertion: the organisation states that it reviewed its captions, and records who did so and when.
Why It Matters
Machine captioning is now the default, and its errors are systematic. A recorded review is what catches them before publication.
