The Sakai Accessibility Working Group is responsible for ensuring that the Sakai framework and its tools are accessible to persons with disabilities. The Sakai Ra11y plan is working towards a VPAT and/or a WCAG2 certification.

CKSource has created a GPL licensed open source version of their Accessibility Checker that lets you inspect the accessibility level of content created in CKEditor and immediately solve any accessibility issues that are found. CKEditor is the open source rich text editor used throughout Sakai. Whlie the Accessibility Checker, due to the GPL license, can not be bundled with Sakai, it can be used with Sakai and the A11y group has created instructions to help you.
