Why WCAG Compliance Checklist

Common questions

Which level should I target?
Level AA (which includes all of Level A) is the standard required by ADA Title II, Section 508, the European Accessibility Act, EN 301 549, and AODA. Level AAA is a stretch goal — even the W3C doesn't recommend requiring it site-wide.
What's the difference between this and the scanner?
Our scanner automates the machine-detectable criteria (roughly a third of them). The rest — captions quality, keyboard behavior, error handling, reading level — need human verification, which is what this checklist tracks.
Is this WCAG 2.1 or 2.2?
This checklist covers all 78 WCAG 2.1 criteria, the version cited by ADA Title II and most current legislation. WCAG 2.2 adds 9 criteria and removes 4.1.1; we note that where relevant.
