The Accessibility Guidelines Working Group has published a Candidate Recommendation of Accessibility Conformance Testing (ACT) Rules Format 1.0. It defines a format for writing accessibility test rules. These rules can be evaluated fully-automatically, semi-automatically, and manually. This common format allows any party involved in accessibility testing to document and share their testing procedures in a robust and understandable manner. This enables transparency and harmonization of testing methods, including methods implemented by accessibility test tools.
This draft is now complete and ready for implementation testing. It addresses all comments received on the previous drafts and provides important clarifications on different requirements. Read about the W3C Web Accessibility Initiative (WAI).
