Is there an IT policy at your school? I suggest perusing it for 2 reasons:
Understanding the consequences of tampering/tinkering with the spyware.
Understanding how much authority the IT department really has, and whether or not what they’re doing with the spyware constitutes overreach.
#2 in particular is for your own knowledge/benefit. Since you’re not an employee, but a student, you may have some inherent rights under this policy, which the IT department may be violating.
