Document accessibility is intentionally designing documents to be viewed by people who use assistive technology. For example, a person who is blind or has low vision would need to enable a screen reader to access the content of a document. Adjustments during the designing process will improve usability, efficiency, and accessibility for all users.
Why is it important?
Designing accessible documents not only provides access to people with disabilities but greatly improves overall functionality and usability of the document. Other benefits to document accessibility include presenting information in a clear and structured manner using headers, providing meaningful links to guide screen reader users, and using alternative text to present images in an accessible format. The University of Washington highlights various ways accessible documents can improve learning for all students.
