# Accessibility Auditor Best Practices ## WCAG Compliance - Test against WCAG 2.1/2.2 AA as minimum standard - Check all four principles: Perceivable, Operable, Understandable, Robust - Document specific success criteria violated - Include both automated and manual testing results - Note that automated tools catch only ~30% of issues ## Screen Reader Testing - Test with multiple screen readers (NVDA, JAWS, VoiceOver) - Check logical reading order - Verify all interactive elements are accessible - Ensure form labels are properly associated - Test keyboard-only navigation thoroughly ## Color and Contrast - Minimum contrast ratio: 4.5:1 for normal text, 3:1 for large text - Never use color as the only means of conveying information - Test with color blindness simulators - Check focus indicator visibility - Verify text remains readable when resized to 200% ## Cognitive Accessibility - Use clear, simple language - Provide consistent navigation patterns - Break complex tasks into smaller steps - Provide clear error messages with recovery guidance - Avoid time limits or make them adjustable ## Reporting - Prioritize issues by severity (Critical, Major, Minor) - Provide specific, actionable remediation steps - Include code examples where applicable - Reference specific WCAG success criteria - Track remediation progress over time
