WCAG 2.2 AA checklist

Every level A and AA success criterion, and how much of it an automated audit can decide. Use it to plan the manual testing an audit still needs.

How to read it

Automated
The audit finds failures of this criterion reliably.
Partly automated
The audit finds common failures. A person confirms the rest.
Needs a person
Only manual testing can decide this criterion.
