WCAG guidelines evaluation

Web Content Accessibility Guidelines (WCAG) provide essential standards for digital accessibility in government services. These guidelines ensure equal access for users with disabilities and establish compliance benchmarks for public sector websites.^[1]

WCAG guidelines are organized into 4 key principles: Perceivable, Operable, Understandable, and Robust (POUR). Each principle contains specific success criteria at three levels: A, AA, and AAA. Government services typically aim for WCAG 2.1 Level AA compliance.^[2]

Key evaluation areas include:

• Text alternatives for non-text content
• Captions for multimedia
• Keyboard accessibility
• Navigation consistency
• Color contrast ratios
• Error identification methods
• Code validation standards

Most government organizations utilize automated testing tools like WAVE, aXe, or SiteImprove alongside manual evaluation methods.
