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.

Key Information Usability Testing
Group: layout • Guideline: structure
Summary in Plain English
An organisational assertion: the organisation states that it ran usability testing with a diverse group including people with cognitive and mental health disabilities, checking that they understood the information hierarchy and menu organisation and could find key information.
Why It Matters
Whether an information architecture works is not something its authors can judge - they already know where everything is.

Generic advice would apply to almost any provision, so none is shown.
