How to Make a Canvas Course Accessible

Canvas courses must be digitally accessible, according to WCAG 2.1 standards. Instructors can use this guide to design accessible web content, scan their course for errors, and decide how to address inaccessible documents used in their course. This guide also summarizes the Seven Pillars of Accessibility, which you should reference when creating digital content.

How do I start?

Are you preparing your Canvas course design for a future term? It’s great to work ahead!

Before You Start: Copy Content to a Sandbox

Do not make changes to a Canvas course from a previous term. This can unintentionally impact the system’s records of student activity.

Instead, create a sandbox course and import content into it. You can create a sandbox course at any time. This sandbox copy of your course will allow you to safely make changes to your course content and experiment as needed.

Please contact the UW-Superior Canvas Team if you need help creating a sandbox or importing content.

Step One: Design Accessible Content

Use the Seven Pillars of Accessibility to design accessible content.

Think about accessibility as you input content into Canvas—it’s easier to create accessible content up front than it is to correct errors after the fact. Check your content every time you add a new item to your modules or edit an existing item.

To confirm your content is accessible as you work, use the Canvas Accessibility Checker built-into the Canvas RCE. Click the stick-figure icon below the RCE text entry box to open the Accessibility Checker.

Use the RCE Accessibility Checker as you create and edit Canvas content. This will minimize the number of errors you need to correct using UDOIT.

Step Two: Scan Your Course with UDOIT

After completing your course, always scan it using UDOIT, a powerful digital accessibility tool available in all UW-Superior Canvas courses. This scan will identify accessibility barriers in course pages, activities, and many published files. UDOIT is listed in the course Navigation menu.

UDOIT identifies many different types of digital accessibility errors, and will provide additional suggestions, which you should usually act on. For more information about how UDOIT identifies errors and makes suggestions, please visit the page linked below.

Introduction to UDOIT: What Errors Does UDOIT Look For?

UDOIT can resolve some issues automatically, but we recommend viewing the page where the issue is located and fixing it there instead. This will make it easier to understand the error and correct it within the context of other information on the page.

Fix all errors that UDOIT identified. Then, fix any suggestions that fall under the Seven Pillars of Accessibility, which we summarize later in this guide.

This page skips from <h2> to <h4>, which is a header sequence error. This error is easier to understand and to correct accurately using the Canvas RCE.

Step Three: Step 3: Scan, Fix, Reupload, and Convert Documents

Unlike errors UDOIT finds in Canvas pages, quizzes, assignments, and discussions, errors in documents used in Canvas usually can’t be fixed with UDOIT.

Instead, you must use the appropriate software accessibility checker outside of Canvas to fix any errors. For example, to fix a Word document used in your course:

  1. Download the document to your computer.
  2. Open it with Microsoft Word.
  3. Scan it with the Microsoft Word accessibility checker.
  4. Fix all errors the checker identifies (plus any issues covered in the seven pillars, regardless of whether they’re identified by the checker).
  5. Delete the old version from your Canvas course and upload the edited version.

How do I fix PDFs?

PDFs are a common type of file used in Canvas courses. To fix PDFs, open the PDF with Adobe Acrobat Pro, available to all UW-Superior instructors. Scan and fix the document with Acrobat’s accessibility checker.

Are there automated options for fixing documents?

If you’re unable to fix a document using the methods listed above, or you’d prefer a simpler option, there are two other options available:

In this video, Cidi Labs shows how to use UDOIT to request a Canvas Page copy of a PDF file used in a Canvas course. UDOIT then replaces instances of the original file with the new page.

The Seven Pillars of Accessibility

In the previous section of this guide, we explained you should use “the Seven Pillars of Accessibility to design accessible content.” Following these principles will help you prevent digital accessibility errors and make content that’s easy to read on a range of devices.

We’ve summarized each of these pillars below. For more detailed information about each pillar, and how to apply them, enroll in our UW-Superior Digital Accessibility Training for Instructors.

Alternative Text

Add text descriptions to non-decorative images in 150 characters or less.

Color Contrast

Ensure that there is sufficient contrast between background and foreground colors. Do not use only color to emphasize text.

Headings

Use the style formats built into the application you're using to add headings. In Canvas, that's the formatting dropdown menu in the Canvas RCE. Start with the lowest-level heading, and don’t skip headings, regardless of how they look.

Links

Make hyperlinks descriptive. Avoid using raw URLs or phrases like "click here."

Lists

Use the provided list tool in the content editor to create all lists. Do not manually create lists by adding hyphens or dashes before lines.

Tables

Format tables with a column and/or row header, as well as a caption. Use tables for comparing data side-by-side, not for arranging text on the page. Don't merge cells or leave cells blank.

Captions & Transcripts

Include accurate captions with videos. Include transcripts with audio-only content.
