This article details a point in the Web Content Accessibility Guidelines and what the implications are for creating accessible course content in Evolve and is part of a larger path.

To view the full guidelines, please visit the Accessibility: WCAG 2.1 and Evolve path.


1.1.1 Non-text Content Level A All non-text content that is presented to the user has a text alternative that serves the equivalent purpose.


One of the more straightforward points. This means all graphical content that is conveying information has some kind of alternative text form that could be read by a screen reader (or other assistive technology). Audio and video are covered separately in the next point.

What does this mean for your Evolve content?

Any diagrams, charts, or images that contain information a learner needs to know must have a descriptive alt tag. An alt tag is a short text description of the content of that image.

There is a provision to add alt tags wherever you need to in Evolve. It is best practice to not add alt tags to purely illustrative images.

For more complex diagrams, flow charts, and more, you may want to consider alternatives to an overly long and complicated alt tag. You may want to break down that visual information into smaller chunks, or maybe even use the Links Component to link to another page in the course dedicated to longer text alternatives for complex graphics.

If applicable, you can make this page separate from any tracking requirements of the rest of the course. You can do this by using the Course Attainment Extension to specify which blocks or components count towards course completion. This way, learners who aren’t using assistive technologies can complete the course without having to visit this page.
