Using the Canvas Accessibility Checker

The CarmenCanvas accessibility checker is a helpful tool within the Rich Content Editor (RCE) that allows you to run a quick accessibility test on the content you have created within the editor. Anywhere the RCE is found — when creating a Canvas content page, an Assignment prompt, a Discussion prompt, etc. With this tool, you can catch common errors that make web content challenging to access for users with disabilities, and you can easily correct those errors before you save and publish your content.  

The Carmen RCE accessibility checker identifies many, but not all, accessibility rules, including the following: 

  • Table structure, including the caption, header row, and header scope 

  • Heading structure 

  • Image alt text 

  • Text contrast 

UX Tip

Validate links

In addition to the Canvas accessibility checker, you can also verify links to course content throughout your course to ensure they are active and working properly. You can check these links using the course link validator, which searches through course content and returns invalid or unresponsive course content links in both published and unpublished content. Learn more about validating links in your course.
