What is UDOIT?

The Universal Design Online Content Inspection Tool, or UDOIT (pronounced, “You Do It”), is a course accessibility checker that allows instructors to scan an entire Canvas course to identify accessibility barriers. After the scan, an instructor can correct some barriers directly through the tool. For barriers that cannot be corrected within the tool, guidance is provided to help an instructor remove the barrier.


Checks for many accessibility barriers, including:

  • Headings in page structure
  • Alternative text for images
  • Table headers
  • Color contrast
  • Video captions

Please note: some items cannot be examined by UDOIT. These include external documents and some videos/audio files for captioning/transcripts. Refer to the Accessible Documents guide, the Accessible Video and Audio Content guide, and Create accessible online course materials for more information on accessibility best practices.

Highlights barriers in the following areas of course:

  • Announcements
  • Assignments
  • Discussions
  • Pages
  • Syllabus
  • Modules



The Universal Design Online Content Inspection Tool (UDOIT) is a Canvas LMS accessibility evaluator that scans a course, generates a report, and provides resources on how to address common accessibility issues.

Student accessibility & usability barriers 

The following information is provided to help people with disabilities know what potential barriers may exist with UDOIT. While UDOIT does have some accessibility barriers for people with visual and motor disabilities, these barriers are not significant enough to prevent the person from improving the accessibility of their course. If you are a person with disabilities who experiences additional barriers not identified in this document, please report those barriers to

Screen reader barriers may be difficult for people with vision disabilities

Some elements on the page lack adequate labels or tags to alert the user of the function of the elements, for example, a button to remove a filter labeled “Active Issues” will read the label to the user, but won’t announce that selecting that option removes that filter. Other elements, like an arrow button to reveal more information, lack contextual labels and simply reads to the screen reader user as “Clickable.”

Keyboard navigation barriers may be difficult for people with vision or motor disabilities

When only using keyboard navigation on the UDOIT Home page, focus gets stuck within a list of radio buttons, and the user cannot access any of the other elements on the screen.

Magnification barriers may be difficult for people with low vision

Content begins to overlap and flow off of the screen when the screen is magnified over 150%.

Color contrast barriers may be difficult for people with color blindness

Some text elements have low color contrast and may be difficult for some users to navigate and read if they have low vision or color blindness.
