Infrastructure generally do, and you could say they are trusted so why not place them in a single community.
If you don't want students to connect directly, place them in an isolated. I'd trust teachers even less :) The method to share files should be by file server.
Don't forget, subnetting and access control. I wouldn't recommend placing all devices in a single subnet. depends on how many you have, but certainly a subnet for end users (teachers, students) and infrastructure would be a good idea.
