For iOS and Mac apps, a download is marked as educational when the app is downloaded by a qualifying educational institution through Apple's Volume purchase for education program.

All apps are eligible to be sold through the Volume purchase for education program unless the developer opts out of the program through App Store Connect.

Educational downloads are usually downloaded in bulk, and may result in spikes in your download trend for the day. For paid apps, educational downloads are usually purchased at a discount so revenue will be lower than you'd expect.
