The Web Content Accessibility Guidelines (WCAG) 2.0 has progressed to a W3C candidate recommendation. The WCAG Working Group are now looking for implementers from a cross-range of websites to help them determine whether or not organisations that have not worked closely with the development of WCAG 2.0 can follow the guidelines.

What is Candidate Recommendation

Candidate recommendation means that the WCAG working group and public reviewers have reached broad consensus that WCAG 2.0 satisfies the working group's technical requirements, and is ready to gather implementation experience. In order to do that, the working group must gather feedback from independent implementations.

In order to demonstrate that all the Success Criteria for a given conformance level can be satisfied within the same site, the WCAG Working Group require at least two independent implementations of every success criterion in the guidelines. They also require at least another four websites that conform at level A, at least another four websites that conform at Level AA, and at least another two websites that conform at level AAA. Implementations should be from organisations that have not been working closely with WCAG 2.0, and from a broad cross-section of websites (web applications, government websites, and so on). The working group are particularly interested in implementation details from websites that include items at risk.

Implementation Feedback

See the intrsuctions for implementors if you intend to submit a website that conforms to WCAG 2.0 at any level. Once you have read the instructions, you should register your intent to submit an implementation through the implementation registration form so that the working group can select a core set of implementations with maximum coverage of the criteria. Questions about the implementation can be sent to

Thank You to the Editors

WCAG 2.0 has been the collaborative effort of many participants working under difficult circumstances. A special thank you should go to the current editors; Gregg Vanderheiden, Loretta Guarino Reid, Michael Cooper, and Ben Caldwell. A special thank you should also go to the previous editors; Wendy Chisholm, John Slatin, and Jason White.
