Web Content Accessibility Guidelines (WCAG) are part of a series
of
Web accessibility guidelines published by the
W3C's
Web Accessibility Initiative. They consist of a set of guidelines on
making content accessible, primarily for disabled users, but also for
all user agents, including highly limited devices, such as mobile
phones.
Priority levels
The guidelines have three priority levels:
- 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 1.0
The WCAG 1.0 were published and became a W3C recommendation on May 5, 1999.
WCAG 2.0
The first working draft of what will become the WCAG 2.0 W3C Recommendation
was published on January 25, 2001, the
latest version on
May 17, 2007. The five year
process encouraged participation in editing (and responding to the hundreds of
comments) by the Working Group, with diversity assured by inclusion of
accessibility experts and members of the disability community.
There has been some criticism[1]
depicting WCAG 2.0 as obscure, vague, and perhaps even a backwards step for Web
accessibility, as well as criticism of the criticism.[2]
