This is the IBM Accessibility Checklist for Web and Web-Based Documentation - Version 6.1. It replaced IBM Web Accessibility Checklist 5.2 on August 25, 2016.
This checklist and its checkpoint pages position IBM web products in preparation for the US Section 508 Refresh, while still ensuring compliance with existing 508 requirements. IBM teams should comply with all of the checkpoints as soon as possible. Review the last section on this page, Using the IBM Accessibility Checklist, for more information.
The Summary of Changes lists all substantial modifications to this checklist since its release.

Legacy Non-WCAG 508 Checkpoints
These checkpoints represent 508 requirements that are not covered by WCAG techniques and need to be tested for all teams. Links in this section open up legacy 5.2 checkpoints.
|
1.1c Image Maps. Client-side image maps are used and alternative text is provided for image map hot spots. Equivalent text links are provided if a server-side image map is used. Disability type: blind |
|
1.3f Cascading style sheets. Web pages are readable without requiring style sheets. Disability type: blind, low vision |
|
4.2a Text-only page. If accessibility cannot be accomplished in any other way, a text-only page with equivalent information or functionality is provided. Disability type: blind |
Legacy 508 Web Checkpoints
These checkpoints represent Section 508 requirements that are subsets of WCAG requirements. If teams pass all WCAG checkpoints, the following can all be reported as compliant. Links in this section open up legacy 5.2 checkpoints.

Using the IBM Accessibility Checklist
Checkpoints are divided into sections that match the standards they reflect or enforce.
WCAG A & AA Checkpoints
A key part of the draft Section 508 Refresh guidelines is that, whether Web, Software or Documentation, user interface components and content of platforms and applications shall conform to Level A and Level AA Success Criteria and Conformance Requirements specified for web pages in WCAG 2.0.
Applications may be web-based or client-side software. Examples of applications are email clients, word processors, help desk systems, content management systems, and e-learning courseware. There will be some additional notes in the rationales or general techniques of some checkpoints on how to apply WCAG 2.0 to non-web software, or if a checkpoint does not apply to software. These software notes can be disregarded by web development teams.
For web teams, little has changed in requirements between the previous checklist and 6.1. Teams migrating from the 5.2 checklist should review the WCAG 2.0 section of Checklist 6.1 to 5.2 Comparison and Impact Analysis for further guidance.
Legacy Non-WCAG 508 Checkpoints
This section encompasses a few existing 508 web requirements which have no equivalent with WCAG checkpoints. By isolating these requirements, teams are able to accurately report compliance with 508 while reporting related WCAG compliance separately. See the Legacy Non-WCAG 508 to 5.2 checkpoint comparison section of the Checklist 6.1 to 5.2 Comparison and Impact Analysis page for information on completion.
Legacy 508 Web Checkpoints
This section encompasses a few existing 508 web requirements which do not match precisely with WCAG checkpoints. By isolating these requirements, teams that do not fully meet WCAG standards are able to accurately report compliance with 508 while reporting related WCAG compliance separately. See the Legacy 508 Web to 5.2 checkpoint comparison section of the Checklist 6.1 to 5.2 Comparison and Impact Analysis page for guidance.
508 Web Documentation Checkpoint
The section has a single checkpoint on documentation (using the 508 Refresh numbering).
