AAA and A but not AA

If something is listed as AAA and A it’s because the success criteria we made the rules for are at those levels.

I’ve created this issue in our tracking system so we can review and make sure this is the best approach to use:

Marking as resolved please follow the GitHub ticket for updates.

But if something is AAA, shouldn’t it also be AA?

Yes

There’s a difference between a website or app being fully AAA compliant and an individual success criterion.

A website cannot be AAA compliant without passing all of the A and AA success criterions. But individual criteria are rated as being either A, AA, or AAA. Some AAA criteria cannot be passed without also passing a related AA criterion (like AAA color contrast will also pass AA color contrast), but some AAA criteria don’t have any related A or AAA guidelines. An example of this is Success Criterion 1.4.7 Low or No Background Audio. This is a AAA criterion that doesn’t have a AA or A version.

The conformance levels on our website refer strictly to the conformance levels of the success criteria that we referenced when creating the check in Accessibility Checker. So it may say AAA and A if we’re referencing a WCAG AAA and a WCAG A success criterion but not a AA one.

I hope that helps.
