iPads used in school use a school AppleId for iCloud, and can use a personal AppleID for the App Store if required. The School iCloud account must be setup on the iPad in order for it to link to our Apple Classroom system, but the App store is optional.
You will have been provided with a school iCloud account, in the format firstname.lastname@example.org
At this point, you are signed into the iCloud account, and you can stop, however, if you wish to add an App Store Account, please scroll down the settings page to find the App Store section.
If you have previously been using an AppleID, you can enter it here. This will allow you to redownload previously purchased Apps.
If you are new to Apple, you can set up your own AppleID here.
