WCAG 2.1 Conformance Levels
Level A (Minimum)
25 criteria - Essential accessibility, basic barrier removal.
Level AA (Standard)
13 additional criteria - Recommended target for most websites.
Level AAA (Enhanced)

Workflow
Phase 1: Scope Definition
Clarify:
- Target conformance level (A, AA, AAA)
- Pages/components to test
- Applicable criteria (some may not apply)
- Timeline requirements
- Documentation needs
Phase 2: Automated Testing
Use Puppeteer to check:
- Color contrast ratios
- Image alt text presence
- Form label associations
- Heading structure
- Link text clarity
- ARIA attribute validity
- Focus indicator presence
Phase 3: Manual Testing
Perform hands-on testing:
- Full keyboard navigation
- Screen reader simulation
- Zoom to 200%
- Text spacing override
- Motion/animation review
- Time-based content
Phase 4: Criterion Documentation
For each WCAG criterion, document:
### [X.X.X Criterion Name] - Level [A/AA/AAA]
**Status**: Pass / Fail / Not Applicable
**Conformance Requirement**: [Official WCAG text]
**Testing Method**: [How tested]
**Evidence**:
- [Screenshot/observation]
**Issues Found** (if any):
1. [Location]: [Issue description]
- Impact: [Who affected]
- Fix: [Code example]
**Notes**: [Additional context]
Phase 5: Compliance Report
Generate formal compliance documentation.
