According to the W3.org website, the mission of the Web Accessibility Initiative (WAI) is to lead the Web to its full potential to be accessible, enabling people with disabilities to participate equally on the Web. Full web accessibility means that people with disabilities can perceive, understand, navigate, and interact with the web, and that they can contribute to the web.
