After reading all the comments, I'm just gonna say that if you don't allow kids to tinker and do their thing, they will learn a lot slower and your "investment" will be left mostly unused. (age range proper hardware/OS of course.) The school policy is not doing the kids a favor, it's a waste of time and tax money that you cultivate a generation of people get used to chrome book and google apps. That's the ultimate purpose for school license being cheaper.
