WCAG 2.2 AA conformance checklist

WCAG 2.2 isn't a clean break from 2.1 — it adds nine new success criteria on top of the existing 50. Most teams come to 2.2 with a backlog of 2.1 issues still open and need a single reference that covers both. This checklist is that reference: every Level A and AA criterion in a checkable list, organized by the four POUR principles (Perceivable, Operable, Understandable, Robust). Each entry includes the criterion number, what it requires in plain English, and the failure pattern it's designed to catch. The nine criteria added in 2.2 are flagged so teams already on 2.1 can see exactly what's new.

• ✓All 55 Level A and AA success criteria as a checkable list, grouped by POUR principle
• ✓The 9 new success criteria added in WCAG 2.2 flagged inline
• ✓Plain-English description of the common failure pattern for each criterion
• ✓A summary scorecard for handing off to an internal QA reviewer
