Digital learning should give every student a meaningful opportunity to participate. Yet a course can become difficult to navigate when a lesson relies on an unlabeled image, a video has no captions, or an assessment cannot be completed with a keyboard.

Accessibility in education is not a single feature to turn on at the end of a course. It is a way to plan, create, and test learning experiences so students can access materials and take part using different devices and assistive technologies. This guide offers a practical starting point for instructors, instructional designers, and teams responsible for learning platforms.

Start With the Entire Learning Journey

Students interact with more than the lesson itself. They may need to find a course, read an announcement, watch a demonstration, download a worksheet, submit an assignment, and check feedback. A barrier at any one of these steps can interrupt the experience.

Map a typical task from start to finish. For example, ask whether a student can find an assignment, understand the instructions, access its materials, submit work, and read the result without using a mouse. Include the learning management system, embedded tools, and files created by instructors in your review.

Accessibility needs vary. A student may use a screen reader, keyboard, captions, magnification, speech input, or a combination of tools. Do not assume that a single setting or automated scan will reveal every barrier.

Organize Course Pages for Easy Navigation

Clear structure helps students find information and understand how a lesson fits together.

  • Use real headings in a logical hierarchy instead of making ordinary text large and bold. Start sections with descriptive headings such as Assignment instructions or Required reading.
  • Give links meaningful names. Read the lab safety guide is more useful than click here, especially when links are read out of context.
  • Break long instructions into short sections and numbered steps. Explain what students need to submit and where to find supporting materials.
  • Use readable text and adequate contrast. Do not rely on color alone to distinguish required tasks from optional ones.
  • Keep recurring information, such as due dates and submission links, in predictable locations across lessons.

These practices can reduce friction for many students, including those who navigate by headings or use magnification. For more guidance, see the W3C’s tips for writing accessible content and our guide to readable text.

Make Images and Visual Explanations Meaningful

A diagram, chart, or screenshot may carry information essential to a lesson. Give informative images text alternatives that communicate their purpose in context. A decorative image that adds no information should not interrupt the reading experience.

For a complex chart, a short alternative alone may not convey the relationships students need to understand. Include a longer explanation in the surrounding lesson, a data table, or another accessible format. For example, describe what changes across a graph and why that change matters to the lesson, rather than only saying graph of results.

When demonstrating software, do not rely exclusively on a screenshot with arrows. Explain the action in text, identify the relevant control by name, and make sure students can follow the instructions without seeing the image.

Plan for Captions, Transcripts, and Audio Description

Video and audio are useful teaching tools, but students need ways to access the same information through different senses.

  • Caption prerecorded video. Captions should convey speech, identify speakers when needed, and include meaningful sounds. Review automatic captions for accuracy, punctuation, and timing, particularly for subject-specific vocabulary.
  • Plan captions for live sessions. Arrange a captioning method before class and make sure students know how to turn captions on. Check the quality and address problems promptly.
  • Provide transcripts. A transcript can help students review a lecture or access an audio-only recording. For video, synchronized captions and a transcript serve different purposes, so do not assume a transcript replaces captions.
  • Describe important visuals. If a demonstration depends on information shown but not spoken, include that information in the narration where possible. Consider whether audio description or an accessible alternative is needed for existing material.
  • Check the player. Students should be able to reach and operate playback, volume, and caption controls by keyboard, and controls should have clear names.

Under WCAG 2.2, captions for prerecorded audio in synchronized media are a Level A criterion, while captions for live audio in synchronized media are Level AA. The prerecorded criterion includes an exception for media that is a clearly labeled alternative for text. WCAG is a technical standard; legal obligations depend on the institution and its circumstances.

Create Accessible Documents and Downloads

A well-organized course page cannot fix a worksheet that students cannot read or navigate. Whenever possible, offer content in an accessible web page as well as a downloadable format. If a file is needed, build structure into the source document before exporting it.

Use heading styles, meaningful link text, appropriate image alternatives, and simple tables with identified headers. For PDFs, check tags, reading order, and keyboard navigation after export. A document that looks organized on screen does not necessarily have a usable underlying structure. Scanned pages may need text recognition and further review before students can use them with assistive technology.

For a more detailed workflow, see our guide to accessible PDFs and documents and the W3C’s guidance on PDF reading order.

Make Assessments and Feedback Usable

A quiz or assignment should measure the intended learning outcome, not whether a student can overcome an unrelated interface barrier. Review the full assessment flow, including instructions, answer controls, errors, submission confirmation, and feedback.

  • Label each input and group related options under a clear question or legend.
  • Give instructions before students need them, including required formats and any time limits.
  • Describe errors in text and offer a useful correction when possible. Do not mark an incorrect field with color alone.
  • Check whether interactive questions, drag-and-drop activities, and embedded tools can be completed with a keyboard. If they cannot, provide an equivalent accessible route and work with the vendor or author to address the barrier.
  • Make feedback available in a form students can navigate and read with their assistive technology.

Plan accommodations and alternative assessment arrangements with the people responsible at your institution. Accessible design and individual accommodations can work together; neither should be treated as a reason to ignore the other. Our accessible forms guide covers labels, instructions, and error handling in more detail.

Test Real Tasks and Make a Plan for Fixes

Automated checks can help identify some issues, but they cannot determine whether a course is understandable or whether a complex interaction works well for every student. Combine them with practical reviews:

  1. Navigate by keyboard. Tab through the course and complete an assignment without a mouse. Check that focus is visible, follows a sensible order, and does not become trapped.
  2. Use a screen reader. Check headings, links, image alternatives, form labels, and feedback in a representative lesson.
  3. Review media and files. Check captions against the audio, inspect document structure, and try embedded players and tools.
  4. Involve people with disabilities. Invite feedback on realistic tasks, compensate participants appropriately, and do not assume one person’s experience represents everyone.
  5. Record and prioritize barriers. Note the affected task, who owns the fix, and when it will be retested. Prioritize barriers that prevent students from participating or completing essential work.

The W3C explains the keyboard accessibility criterion, including its limited exception for functions that depend on the path of movement. For a broader testing process, read our website accessibility audit guide.

Build Accessibility Into Course Maintenance

Courses change each term. New readings, recordings, links, and third-party tools can introduce new barriers even when an earlier version worked well. Give course authors a short checklist, review materials before they are assigned, and provide a clear way for students to report problems and request support.

Start with one high-impact course or student journey, fix what you find, and use those lessons to improve your process across the organization.
