A, AA, AAA: Picking the Right Target
Why AA is the standard most teams commit to.
Three Levels, One Standard
WCAG defines three conformance levels: A, AA, and AAA. Each adds more success criteria, raising the bar for how usable your site must be.
Level A: The Floor
Level A is the bare minimum. Miss it and content can be completely unusable, like an image with no alt text or a control you cannot reach.
