Alternative text is a text description of an image that is read aloud for someone using assistive technology. Learning to write effective alternative text for data displays enables you to describe key data trends or share the relevance of the data to the surrounding text.
When working with Individuals with Disabilities Education Act (IDEA) data, this might mean providing a text description for a bar graph showing graduation rate trends over time for students with disabilities. IDEA data should be accessible to everyone, most of all, the people with disabilities whose experiences the data represents.
