Personally, if you have met all of the WCAG priorities, then you are
WCAG compliant. As far as Bobby's icon - it really doesn't mean
anything except that Bobby was able to evaluate a FEW of the WCAG
priorities and found no obvious errors. Nearly all of the priorities
cannot be verified with ANY automated validator. For this reason, the
Bobby icon has become a bit of misnomer with accessibility. The Bobby
site states that you must also perform the manual checks it lists
before posting the icon.

For example, a study I heard of found that around 80% (if I recall
correctly) of US Government Web sites that display the Bobby icon don't
even pass Bobby 508. There's a real danger in assuming that passing
Bobby (or validator X) means that you are accessible, when in fact
Bobby or any other validation program can only check a FEW of the
necessary checkpoints. I think Bobby checks 4 of the 16 Section 508
Checkpoints, and of those, a human check is still necessary to ensure
accessibility. Bobby can check that alt text is present and will say
that your page is accessible if you have alt text, but it can't check
to ensure that the text is equivalent and appropriate, as is required
by the accessibility standards. The posting of the Bobby (or whatever)
icon tends to reinforce the false idea that Bobby compliance standards compliance = accessibility, which is often far from true.

Still, if you have done the manual checking, feel that you are
compliant, and want to share this with your site visitors (most of
whom could probably care less), then go ahead and post the icon. You
might also look at the official W3C icons -
