The first part of this series focused on starting an inventory of your learning materials in UVACanvas to help you manage the scope of your accessibility work. That process included deleting what you don’t need and archiving items for historical or reference purposes.

Now what’s left is what you’re keeping. The next step is to assess the accessibility of those remaining materials, to learn which ones are in good shape and which ones need some improvement. In this article, we’ll explore tools and practical techniques you can use to assess your courses.
Automated accessibility assessment
There are lots of ways to test or review the digital accessibility of your course materials. The most comprehensive approaches involve automated testing, manual methods like screenreader or keyboard-based testing, and usability testing performed by people with disabilities.
But when you’re working on your own Canvas course materials, you likely won’t have the time or resources to test everything at these three levels. Here we’ll focus on how you can check your own materials with automated assessment tools.
While these tools are a great way to improve accessibility very quickly, it’s important to also understand their limitations. An automated tool can detect if alternative text is present for an image, for example, but only a human can tell if that alternative text helpfully describes that image in context. Some kinds of accessibility issues can’t be detected by automated tools at all.
While automated tools can be very helpful, they’re no substitute for applying good practices like those described in the Seven Pillars of Digital Accessibility when you’re creating new materials.
UDOIT Accessibility Report
The best starting point for assessing your Canvas courses is a tool called UDOIT (Universal Design Online content Inspection Tool), which we discussed in our previous article. In your course navigation menu on the left, select “UDOIT Accessibility Report” and the tool will scan your course, identifying opportunities to improve its accessibility and coaching you on what to do next. UDOIT scans two types of materials:
- Canvas content: these are items you’ve created in Canvas, such as pages, modules, announcements, assignments, discussions, etc.
- Files: these are items you’ve uploaded to Canvas, such as Word, Excel, PowerPoint, or PDF documents.
The tool builds a list of “issues” for you to work on and summarizes them in a “Course Accessibility Score,” expressed as a percentage. The following screenshots are intended to help you feel more comfortable with navigating the UDOIT interface and understanding its assessment of your materials. The next article in this series will dig further into how to prioritize and work with those findings to improve your materials.

The findings of the UDOIT scan will be presented on a “dashboard” like the one above, that prominently features the Course Accessibility Score (in this example 79%), but also breaks that down into a “Scorecard” with three accordions: High Impact, Medium Impact, and Low Impact issues.

When you open one of the high, medium, or low impact accordions, you’ll see a list of Issue Types that correspond to that impact level. Click on one of the Issue Types (in this example, we’ll select ‘Color’) to see the individual instances of that issue type found in your course. Depending on the issue type, this will take you to a filtered issue list in the UFIXIT tab (for issues with Canvas content) or the Review Course Files tab (for issues with uploaded files). As you can see in the screen shot below, you can toggle between these tabs at the top of the UDOIT Accessibility Report.
Within each list of issues of a given type, you’ll notice these errors are classified as “Errors” or “Suggestions”:
“Errors” (identified with a red exclamation point icon in a circle, as seen in the following screenshot of “Colors” issues) are barriers that will definitely need work to meet accessibility standards.

“Suggestions” (identified with a blue “i” for information in a circle, as seen in the following screenshot of “Links” issues) are items that may need work, but will require human review to be certain.

Click on the “Review” button at the end of the row to see details about a specific issue instance.

When you click ‘Review’, a dialog box will open with information and coaching on how to improve the issue. Review the coaching instructions and look for the yellow highlighting in the Preview box for an indicator of where the problem is located. In our example, the text “Complete in advance of the first session” is text in the page that is highlighted. For many types of issues with Canvas content, you’ll be able to address the issue from right within the UFIXIT dialog box. In other cases, you might need go out to the individual page to make improvements.
As you address issues, you can click the “Next Issue” button in the bottom right of the pop up box to move to the next issue of that type, or you can close that dialog box and click back to the “Home” tab to return to your dashboard and continue the process with other issue types. Being comfortable with navigating through the UDOIT interface will help prepare you for prioritizing and improving your course accessibility, which are processes I’ll explain more in the next article in this series.
Again, it’s important to emphasize that because UDOIT is an automated assessment tool, it only scans for certain types of issues (and you can review that list: What Does UDOIT Look For?) As a result, a 100% Course Accessibility Score in UDOIT doesn’t guarantee your course is 100% accessible.
You may find, after review, that some of the issues categorized as “suggestions” are actually not accessibility barriers at all. For example, UDOIT may flag a link as having non-descriptive text when in fact, UDOIT just doesn’t understand the link text correctly. In those cases, you can manually resolve them using the “Mark as Resolved” checkbox. But even if the UDOIT score is not a perfect measure of your course’s accessibility, every point you advance toward a 100% score is a step toward a better, more usable, and more accessible course for all students.
Beyond UDOIT: Assessing Files
Just as with content created in Canvas, UDOIT only scans for certain issues in uploaded files. This ULEARN Accessibility Guide explains more about the issues UDOIT looks for in uploaded files.
You can fill some of the gaps in UDOIT’s findings by also scanning those documents with other automated tools. Microsoft’s Accessibility Assistant (also known as the Accessibility Checker) is available in Word, Excel, and PowerPoint, as well as OneNote, Outlook, Visio and Sway.

The “Check Accessibility” option can be found in approximately the same place in all those applications: If you select the “Review” menu in the Ribbon, you will see a Check Accessibility button and dropdown that you can expand for additional options.
Like UDOIT, Microsoft’s Accessibility Checker and Assistant will identify opportunities to improve your document and guide you on how to make those improvements. Still, the same caveat applies: as automated tools, they won’t catch everything, but they are a good start, can help a lot, and may find opportunities that UDOIT misses.
When it comes to assessing PDF files, UDOIT also provides fairly limited feedback. If you have access to Acrobat Pro, its Accessibility Checker can help provide a more complete and helpful assessment of your PDF documents.
Of course, the difference between UDOIT and tools such as Microsoft Accessibility Checker is that UDOIT scans your entire course, while these other tools assess documents one at a time. That means you may need to prioritize your assessment work by determining the most important, essential or impactful documents first. To help you with that prioritization, refer back to the inventory you created as part of the previous article in this series.
What’s next
Hopefully this assessment process will reveal that you’ve got lots of materials that are already “good to go” and don’t require additional improvement work, or are “low-hanging fruit” that you can improve quickly and easily. Once you set these items aside, you can focus on the ones that need improvement. Like the rest of the process described in these articles, you should approach improvement strategically, considering both the effort that will be required to improve a given item as well as the impact that improvement could have for your students.
The next article in this series will guide you through prioritization and improvement of your materials, so your efforts can have the most benefit for the most students on an optimized timeline.
