Evaluation and tools

WCAG 2.0 has 12 guidelines that are organized under 4 principles:

  • perceivable,
  • operable,
  • understandable and
  • robust.

For each guideline, there are testable success criteria, which are at three levels: A, AA, and AAA.
A guide to understanding and implementing Web Content Accessibility Guidelines 2.0 (WCAG 2.0) is available on the W3C website.
