Section 508.
If you sell software or digital services to a US federal agency, this is the one that decides whether you can bid.
What it covers
Section 508 of the Rehabilitation Act requires federal agencies to make their electronic and information technology accessible. The Revised 508 Standards incorporate WCAG 2.0 Level AA by reference and apply it to web content, software and electronic documents.
The practical effect reaches far beyond government: agencies must procure conforming technology, so their suppliers have to demonstrate it.
VPATs and ACRs
A VPAT is the template. Filled in, it becomes an ACR — an Accessibility Conformance Report — stating, criterion by criterion, whether your product supports it, partially supports it, or does not.
A self-assessed ACR carries real risk. If it overstates support, that is a misrepresentation in a procurement process, and the liability for remediation flows back to you. Procurement teams increasingly prefer independently tested reports for exactly this reason.
We produce ACRs from actual test results, including the rows where the honest answer is “does not support”. That is more useful to a buyer than a page of green, and considerably safer for you.
This page explains our understanding of the landscape as of August 2026. It is general information about the standards we test against — it is not legal advice, and we are not lawyers. For your own obligations, talk to one.
