*** Important Note ***

The IBM Accessibility Checklist - Version 7.1 is now available, and is required for compliance starting January 1, 2020.

This updated version of the accessibility checklist unifies guidance for web content, non-web applications (software) and documentation into a single checklist that can be used to assess compliance with the Revised Section 508 standard in the United States, as well as the European EN 301 549 standard.

The older checklist version originally at this location is still available at IBM Accessibility Checklist for Web and Web-Based Documentation - Version 6.1.
