The Accessibility Checker is an easy to way to check your document for common accessibility issues.
Mac users: Accessibility Checker is available starting with PowerPoint for Mac 2016
Use common fonts like Arial and Times New Roman.
2. Use the lists built into PowerPoint
Using the list buttons in PowerPoint helps screen readers users know when a list begins and makes it possible to move between list items. Avoid creating lists manually with dashes or other symbols.
List buttons can be found on the home tab for both Mac and Windows versions.
3. Use colors that contrast well
- Do the text and headings strongly contrast from the background?
- Would everything still be easy to understand if printed from a black and white printer?
4. Avoid using color as the sole way to convey meaning
Some people may not detect change of color. Screen readers don't announce colored text or highlights. You can use colors, but also share the information in a way that doesn't only rely on color to convey the message.
Example of using color to communicate information via text:
"Fox" and "dog" are nouns in the following sentence:
The quick brown fox jumps over the the lazy dog.
Make sure all text content appears in the outline view, as this is the primary way some students read the content. Also, ensure there is a unique title for each page.
It is recommended to begin in the outline view, then change the design and add images.
Alternative Text (Alt-Text) provides brief descriptions of images for use with screen readers. Read more about writing Alt text

Video and Audio
Instead of inserting the audio or video file directly within your presentation, insert a hyperlink to the external media. Embedded video and audio in PowerPoint can be difficult to check for accessibility. Keyboard accessibility, video captions, and screen reader compatibility are just some of the issues that arise with embedded media.
Note that the video content you link to should have captions for the deaf and the hard-of-hearing.
