    Maybe just using signal jammers in each classroom would suffice. But then the teachers are out of luck as well.

      Are those legal? In the Netherlands they're not, I believe, because it would suck to have a shooting or a seizure and not be able to call the police/ambulance/superheroes

        Well if the head honcho had an on/off switch,that would work,or an old fashioned land line.
