WCAG (Web Content Accessibility Guidelines) levels

I am trying to familiarise myself with the WCAG guidelines - most of the requirements have either level A, AA or AAA. Are these relevant, i.e. is A a bare minimum standard, and AAA the ultimate best practice in accessibility, or are the levels representing something else?

The various levels are no a set of best practices but rather a set of requirements to be met to conform to that level of accessibility.  Each successive level has increasingly restrictive/specific requirements placed on the design of the object/element.

The levels represent the extent that the developers have gone to, to build an site/app that is as accessible as can be, based on the WCAG.

THanks, so to be AA compliant, you must conform to all level A and AA requirements. And to be AAA compliant (advanced), you must confirm to all requirements, A-AAA
