I work part time for a local government authority, and we are working on making all our digital content accessible.
I recently attended a (very thorough) course on accessibilty using indesign which was great but the trainer suggested that using the Acrobat accessibility checker wasn't sufficient - ie a PDF could pass all of the checks but still wouldnt necessacarily be accessible enough to meet the WCAG standards.
I wondered if anyone had any experience of this, could recommend any further checkers to ensure we meet the AA level of requirement by WCAG!
Nothing takes the place of a human that is well-trained in accessibility!
(But that gives you job security, right?) <grin>
Suggestion: Maybe post your question to the PDF Accessibility group on Facebook. It's just for PDF accessibility professionals. Lots of great ideas, comraderie, and advice. https://www.facebook.com/groups/PDFAccessibility You'll get a good cross section of people's thoughts about checkers.
