The World Wide Web Consortium (W3C) sets the main international standards for the World Wide Web and its accessibility. W3C created the Web Content Accessibility Guidelines (WCAG 2.0) which are similar to Section 508, but on an international level. WCAG 2.0 requires specific techniques for compliance and is more current than Section 508.
Many countries and international organizations require compliance with WCAG 2.0. The guidelines are categorized into three levels of compliance: A (must support), AA (should support), and AAA (may support). Representatives from the accessibility community around the world participate in the evolution of these guidelines.
Web Content Accessibility Guidelines (WCAG) is developed through the W3C process in cooperation with individuals and organizations around the world, with a goal of providing a single shared standard for web content accessibility that meets the needs of individuals, organizations, and governments internationally.
