Apologies, Steve.
Your last comment helps clear up what you originally wrote
/quote if a PDF passes an automated PDF/UA check, it's usually a good sign because you can't pass it by accident. /endquote.

What do you mean by "an automated PDF/UA check?
— It passed Acrobat's built in PDF checker?
— It passed a 3rd party checker, like PAC or Commonlook?
— It passed a manual check and testing with assistive technologies? (although I wouldn't consider this an automated check!)

Acrobat's automated checker will pass a document with just P tags, or with a scan for the entire page and tagged as Figure with Alt Text that says "graphic of text." Acrobat's checker does indeed pass these failed PDFs by accident.

Even better checkers like PAC and CommonLook don't find mis-tagged content, poor reading orders, or a stack of figures at the bottom of the tag tree of a 350 page book.

But if you mean the whole enchilada of checking PDFs (automated + Human), then yes, I too assume that the file is probably fairly accessible to most people and their technologies.
