It seems like a wifi/bluetooth jammer would be a far more sensible option. They can be a few hundred dollars, but in terms of man hours required to remove board level components it's nothing . Like @danj says removing the components removes the ability to update the device. You might consider looking for a tablet that has some sort of admin service that can allow settings to be changed by a admin but not by a user, there may even just be apps on the app store that allow admin privileges. You might also consider creating a custom ROM with no drivers for connectivity, but that seems like a lot of work. I'll add that my little sister goes to a school that has free wifi in all the buildings, I think it's rather stupid idea to cut people off from the internet that has so much to offer interms of self-education. They have a tech admin team that block access to facebook and snapchat etc. But what about cheating? I went to school in the days with no smart phones and cheated my way to the top just fine.
