What does WCAG 2.2 AA conformance mean?
In short and in plain language
The WCAG have levels. Level A is the basic level. Level AA is the usual goal. Level AAA is the top level.
Level AA means: all points from A and AA are met. These include good contrast, keyboard use and text for images.
The level applies to the whole page. A single fault can break it. We check this closely.
WCAG defines success criteria at three conformance levels: A (basic), AA (the recommended standard) and AAA (the highest level, often not achievable for all content). Conformance at level AA means all A and all AA criteria are met, for example 4.5:1 text contrast, full keyboard operability, meaningful alternative texts and consistent navigation.
AA is the decisive target in practice: it is referenced by EN 301 549 as the minimum requirement and is internationally recognized. AAA is rarely required in full, because individual criteria are not feasible for certain content types.
Importantly, conformance applies per page: a single unreachable element can break a page's conformance. It is exactly this completeness that we check systematically in our WCAG audit.
