There is no switch, no certificate and no register, so the question has to be turned into a measurable one: does the site meet WCAG Level AA, on which pages, tested when, with what outstanding? That is the claim a court, a procurement reviewer and a customer can all check. This page is how to answer it about your own site in an afternoon. On the worked example the answer is 72% of the AA criteria passing, with 401 issues and $15,872 between here and the rest.
Turn the question into a measurement
Pick your templates, run a scanner, then do a keyboard pass and a screen reader pass on two pages of each. Count the criteria failing rather than the issues: fourteen of fifty on the worked example is 72% passing, which is a sentence you can say to a lawyer, a customer or a buyer without overclaiming anything.
What compliant means in practice
Meeting WCAG 2.2 Level AA across the pages that matter, with the evidence to show it and a statement listing what is outstanding. Nobody sensible claims a large site is perfect: the defensible position is a standard, a date, a scope and a programme, which is exactly what a published statement carries.
How to answer it out loud
We aim at WCAG 2.2 Level AA. We last audited on this date, covering these templates. Fourteen criteria were failing; ten are fixed and the rest are scheduled by this date. Here is our statement. That paragraph is worth more than any badge, and every part of it is checkable, which is what makes it credible.
Questions people ask about what is an ada compliant website
Is my site ADA compliant?
Nobody can tell you yes without testing it. Run the checks above and you will have a defensible number rather than a hope.
Does my website need to be ADA compliant?
If your business serves the public in one of Title III's categories, the Department of Justice's guidance says yes; the practical answer for almost anyone selling online is to comply.
Does my website have to be ADA compliant if we are tiny?
There is no headcount exemption for serving the public. The site is smaller, so the work is smaller.
