About Web Content Accessibility Guidelines (WCAG) 2.0

The Web Content Accessibility Guidelines (WCAG) documents explain how to make Web pages and Web applications accessible to people with disabilities. WCAG is developed through the W3C process in cooperation with individuals and organizations around the world. A primary goal is to provide a single shared standard for Web accessibility that meets the needs of individuals, organizations, and governments internationally.

WCAG itself is a technical standard designed primarily for Web developers and designers, authoring tool and evaluation tool developers, and others who need a technical standard for Web accessibility. WAI develops additional material for people with different levels of accessibility knowledge.
