Also known as “WCAG 2 test rules”, Accessibility Conformance Testing (ACT) rules describe how to test conformance to Web Content Accessibility Guidelines (WCAG) success criteria. They are primarily intended for usage by developers of evaluation tools and test methodologies. These rules can be broken down into two different groups:
- approved rules
- each rule in this group has been officially approved by W3C, and at least a tool that implements it exists.
- proposed rules
- each rule in this group either needs to be officially approved by W3C, or requires a working implementation
ACT rules are described in a very well defined format, documented in the ACT Rules Format W3C recommendation.
