WCAG Compliance Levels describe how closely digital content meets accessibility standards. WCAG includes three levels of conformance: A, AA, and AAA.
Level A — Minimum Accessibility
Addresses the most basic accessibility barriers
Provides limited access for users with disabilities
Often not sufficient on its own for public schools
Examples:
Images have alt text
Videos do not auto-play with sound
Content can be accessed with a keyboard
Level AA — Standard for Schools and Public Agencies*
Builds on Level A and addresses the most common accessibility needs
This is the level most required for K–12 public schools
Aligns with federal guidance and enforcement expectations
Examples:
Strong color contrast for text
Captions for pre-recorded videos
Clear headings and consistent navigation
Forms with labels and helpful error messages
Level AAA — Enhanced Accessibility
Highest level of accessibility
Not required for most public organizations
Can be difficult to achieve for all content
Examples:
Sign language interpretation for videos
Very high contrast ratios
Extended audio descriptions
