WAI Interest Group (IG) Charter

The mission of the WAI Interest Group (WAI IG) is to promote awareness of, and engagement in, accessibility-related work throughout W3C. This includes augmenting wide reviews of WAI deliverables, and augmenting APA WG's review and discussion of accessibility aspects of deliverables being developed in W3C groups, including specifications, research topics, and educational materials; exploring web accessibility issues and solutions; and sharing information about web accessibility activities around the world.

The WAI IG enables exploration and contributions to W3C groups' deliverables by members of disability communities, research organizations, industry, government, and others who have an interest in web accessibility, yet may not have time to directly participate in more focused work of those groups; and from those who may participate in one or more accessibility-related groups, but also wish to follow progress across all areas of accessibility work at W3C.

WAI IG is a well-established Interest Group with over a thousand participants. It is focused on understanding and implementing web accessibility guidelines and specifications, and increasing awareness of accessibility. The WAI IG's on-going discussion of general as well as technical issues related to web accessibility contributes to a comprehensive accessibility approach at W3C.

Out of Scope


The function of the WAI Interest Group is to serve as a forum for the exchange of ideas, including augmenting the review and discussion of accessibility aspects of deliverables from W3C groups; and to engage participation into the work of those groups. The WAI IG does not directly develop deliverables, nor replace the review and development which specific accessibility-related W3C groups are chartered to do.

Success Criteria


W3C Groups

The WAI IG provides a forum for review and discussion of draft deliverables from the following groups, among others:

  1. Accessible Platform Architectures Working Group (APA WG)
  2. Accessibility Guidelines Working Group (AG WG)
  3. ARIA Working Group (ARIA WG)
  4. Education and Outreach Working Group (EOWG)
  5. Internationalization Working Group, to explore intersections between accessibility and internationalization


Participation in the WAI Interest Group is open to the public. There are no minimum requirements for participation in this group. Participants are strongly encouraged to take advantage of frequent opportunities to review and comment on deliverables from other groups.

The Chair may call occasional meetings consistent with W3C Process requirements for meetings.


This group uses the public mailing list w3c-wai-ig@w3.org (archive) for discussions, and the public announcements list public-wai-announce@w3.org (archive) for announcements. Specific input to documents offered for review can be made via input options specified in those documents and in the review notice posted on the WAI IG list. Information about the group is available from the WAI Interest Group home page.

Decision Policy

Consistent with its mission, this group is not a decision-making body, but rather provides a forum for discussion and advice on different topics relating to web accessibility.
