Systems and methods presented herein can allow a teacher to manage student devices in a classroom setting by grouping student devices on a graphical user interface and using the interface to set locks with respect to the groups of student devices. Lock requests can be received and managed by a server, which can issue file locks, web locks, and application locks. These locks can restrict file access, website access, and application access, respectively, on the students' personal mobile devices. Additionally, the teacher device can allow the teacher to provide timing information in conjunction with the lock requests, which can control when to lock and/or unlock the student devices.
