A simple live Kahoot! that uses the game’s default settings will be inaccessible to many students with disabilities. Through our testing and research, the Digital Accessibility Services Team (DAS) identified the top 6 most significant accessibility barriers in a live Kahoot!:
- Time Limits: Generally, the default time limits on questions do not provide players with reading or learning disabilities or players who use assistive technology enough time to navigate the screen, locate content, and answer questions.
- Screen Reader Incompatibility: Players who are blind or visually impaired are unable to respond to questions using a screen reader unless “Show questions and choices” is enabled. Even then, many question types are not compatible with screen reader technology. (Refer to the section on accessibility of question types for more details).
- Screenshare Content Not Accessible: Players who are blind or visually impaired cannot access any content presented through screenshare including leaderboard, points awarded to other players, poll responses, podium finishers, and so on.
- Keyboard Operability is Challenging: Players who navigate using only the keyboard are significantly challenged by low contrast of the focus indicator. Furthermore, responding to drag and drop question types using a keyboard is not always practical.
- More Points for Quicker Responses: By default, response time is a factor in the number of points a player receives when answering a question correctly. This feature disadvantages nearly all players with disabilities who require more time to perceive, read, and process information, as well as users of assistive technology.
- Distracting Music: Background music can be distracting to many players, impedes focus, and may interfere with assistive technology.
