Apple Classroom

With Classroom, student iPad devices can be managed only in class and no data is stored after a class session ends. The teacher and students need to be in close proximity, signed on to the same Wi-Fi network, and in an active class session. The teacher cannot manage or view student devices outside of class. To ensure transparency when Screen View is active for a student’s screen in class, a notification at the top of their screen indicates that the screen is being viewed. Schools can also choose to disable Screen View if they prefer that teachers not view student screens. -- Data and Privacy Overview for Schools
