Accessibility tools for creating content in Canvas

Last updated: September 26, 2022
Audience: Instructors

There are two tools available in the Canvas Rich Content Editor (RCE) to assist in detecting and correcting accessibility issues with course content built in Canvas:

What if the tools show different scores?

The Ally WYSIWYG tool and the Canvas Accessibility Checker may find and highlight different accessibility issues in a course. Each tool’s search is based on a different but similar set of parameters and rules. Any corrections should have a positive impact on the feedback from both tools.

In the effort to create accessible content for students, more information is better. The tools are not competing; they’re covering as many issues as possible and providing a variety of assistance. You may find that you prefer the style of one tool over the other, so take the time to work with both and make choices that work best for you and your content.

Canvas Accessibility Checker

The Canvas Rich Content Editor (RCE) includes an accessibility tool that detects common accessibility errors within the editor. You can use the Accessibility Checker to design course content while considering accessibility attributes. This tool only verifies content created within the Rich Content Editor.

How do I use the Accessibility Checker in the Rich Content Editor as an instructor?


The Ally WYSIWYG tool (pronounced wiz-ee-wig) provides real-time feedback from Ally in the Canvas Rich Content Editor (RCE). As you create content, the Ally score updates in real-time. Its name is in reference to the acronym for “what you see is what you get”, WYSIWYG, which describes the type of editor that is used in Canvas.
