WCAG
The Web Content Accessibility Guidelines are part of a series of guidelines produced by the Web Accessibility Initiative. They are a set of guidelines concerning website accessibility, primarily for disabled users. They also cover all user agents, including mobile phones. The current WCAG version is 2.0.
Priority levels
The guidelines have three priority levels:
- Priority 1. Web developers must satisfy these requirements. It will be impossible for one or more groups to access the web content if these requirements are not met. Conformance to this level is described as 'A'.
- Priority 2. Web developers should satisfy these requirements. If these requirements are not met 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 should satisfy these requirements to make it easier for some groups to access the web content. Conformance to this level is described as 'AAA' or 'triple A'.

WCAG tests are part of the accessibility test that I can carry out as part of the accessibility tests on your website.
