What is the difference between WCAG A and WCAG AA conformance?

Post by Accrete »

Confused about the different levels of WCAG conformance? This article explains what the different levels are:
The three levels of WCAG compliance

The success criteria are arranged in 3 levels:
• A - Minimum level – without addressing these items barriers exist that cannot be overcome by assistive technology.  This level affects the broadest group with the most benefits and is essential.
• AA - More accessible – Even with minimum support some barriers will still exist for some people.  Not meeting criteria at this level may have an impact on certain groups of users and address the criteria may impact the look of a page to a greater extent or affect site logic.
• AAA – Even more accessible – Some Level AAA criteria cannot be applied everywhere, so level AAA is generally not required. That being said, even meeting level AAA does not make web pages accessible to everyone.

The criteria are cumulative—to conform to Level AA, you must first conform to A. To conform to Level AAA, you just first conform to A and AA.
