wcag-aaa — WCAG 2.2 Level AAA Auditor

Audits web content against WCAG 2.2 Level AAA success criteria, covering enhanced requirements beyond the AA baseline.

Features

• Audits all Level AAA success criteria from WCAG 2.2
• Enhanced contrast evaluation (7:1 for normal text, 4.5:1 for large text)
• Extended audio description checks for prerecorded video (1.2.7)
• Sign language interpretation requirements (1.2.6)
• Reading level analysis targeting lower secondary education level (3.1.5)
• Abbreviation expansion detection (3.1.4)
• Pronunciation guidance checks (3.1.6)
• Focus appearance enhanced requirements (2.4.13)
• Target size minimum 44x44 CSS pixels (2.5.5)
• Context-sensitive help detection (3.3.5)
• Error prevention for all submissions, not just legal/financial (3.3.6)
• Prerequisite verification: confirms AA conformance before AAA audit

When to Use It

• Your organization targets AAA conformance for specific content areas
• Evaluating content intended for audiences with specific accessibility needs
• Government or public sector projects requiring enhanced accessibility
• Educational institutions aiming for maximum content accessibility
• After achieving AA conformance and wanting to identify AAA improvement opportunities
• Accessibility maturity assessments where AAA criteria serve as stretch goals

How It Works

1. Prerequisite check — Confirms the page or component has been audited at AA level first; if not, defers to accessibility-lead for baseline audit
2. Scope definition — Identifies which pages, components, or content areas to audit at AAA
3. Criteria evaluation — Evaluates each AAA success criterion against the target content
4. Finding classification — Reports findings with WCAG criterion reference, severity, and remediation guidance
5. Priority assessment — Ranks findings by impact and feasibility, noting that full AAA conformance is rarely expected for entire sites

Handoffs

Receives from	contrast-master	When enhanced contrast checks (7:1) are specifically requested
Hands off to	accessibility-lead	When prerequisite AA audit has not been completed
Hands off to	contrast-master	When detailed contrast analysis is needed for 7:1 threshold evaluation
Hands off to	cognitive-accessibility	When reading level or cognitive criteria need deeper analysis
