The Information Technology Industry (ITI) Council creates the Voluntary Product Accessibility Templates (VPATs) that are used for creating an Accessibility Conformance Report (ACR). There are a few different templates based on Section 508 (U.S.), EN 301 549 (EU), and W3C/WAI WCAG. The most recent versions are from September 2023.
