Students are afforded very little privacy. I'm sure you've heard of administration software that lets school staff view and control student's computers remotely. One of my teachers even showed to the class that he was able to view the screen of a student who was absent from class, without the student's knowledge. The software also logs keystrokes (yes, including passwords) and browsing history. If that wasn't bad enough they also enforce custom certs so they can MITM ssl traffic. Many students log into their personal accounts on their school computers without realizing that they've compromised their passwords and sensitive personal information.
Schools are also notoriously bad at security. My school force disabled Firefox updates, meaning every browser remained unpatched after multiple CVEs, one of which allowed websites to execute arbitrary code on the host's machine (sandbox escape).
