Only the school can remove them from the system, and although Apple's terms of service _require_ them to be in control of the device for it to be registered (i.e. not sold to a third party, me), I have been completely unable to convince the school to help me on the matter. Contacting Apple doesn't seem like much of an option either, as they don't even publicly post contact info for this kind of support.
