WCAG 2 consists of 13 guidelines organized under 4 principles (perceivable, operable, understandable, and robust) and each guideline has testable success criteria.
WCAG 2 uses three levels of conformance:
- Priority 1: Web developers must satisfy these requirements, otherwise it will be impossible for one or more groups to access the Web content. Conformance to this level is described as A.
- Priority 2: Web developers should satisfy these requirements, otherwise some groups will find it difficult to access the Web content. Conformance to this level is described as AA or Double-A.
- Priority 3: Web developers may satisfy these requirements, in order to make it easier for some groups to access the Web content. Conformance to this level is described as AAA or Triple-A.
WCAG 2.2 was published on Oct, 2023 and WCAG 3.0 is in development.
