Every government school here uses Linux. And there's no security (password is "password" even for root account). The only reason it works is because everyone has common sense on what they shouldn't do. The worst any kid could do is visit a "bad" site on a browser because no one knows how to do anything else.
Even the exam software assumes you don't know how things in Linux works:
The scores and answers are stored in simple non-encrypted SQLite3 databases at a directory in /usr/share.
