Why it matters:
Images often carry essential meaning, whether it’s a chart showing data trends, a photo illustrating a concept, or a graphic that reinforces course content. Without alt text, students who are blind or have low vision may miss that information entirely. A screenreader will simply announce “image” or “blank,” leaving the student without additional context.
Adding alt text ensures that all students can access the same information, regardless of how they engage with the material. For example, a chart labeled “Enrollment growth from 2015–2025” may be described in alt text as “Line chart showing steady enrollment growth of 25% from 2015 to 2025.” This gives students the key takeaway without overwhelming detail. Alt text also benefits students in low‑bandwidth situations where images don’t load, ensuring the message still comes through the way you intended.
Adding alt text is quick and built into most of the tools we already use. In Microsoft Word and PowerPoint, right‑click the image and select “Edit Alt Text.” In Google Docs, right‑click and choose “Alt text.” In Brightspace, the option appears when you insert an image. You can even add alternative text to your posts on most social media platforms.
