In a school library I have 30 iPads to set up for teachers to use in their classrooms. In a school library with 30 iPads on a cart.  Should one appleid be used for all 30 iPads?  I will be the only one adding the apps, and then the cart will be taken to classrooms.  The same apps will be on all iPads.  Would it be better to just create a genric appleid or an iCloud id, or what's the best way to do this?
Apple has a tool, Apple Configurator, designed to help manage multiple devices in exactly this kind of scenario.  I haven't personally used it, but it sound like what you need.
