This year the school's director wants to completely block Internet access for all the student's personal devices.

The silent premise in this request is that all student Internet access occurs through the school's gateway. Which is of course false.

If the objective is to prevent misuse of school resources for non-education purposes then the premise, while faulty, is fine. If the objective is to restrict students' Internet access in its entirety then this is doomed to fail.

Have you clarified with the director that only access through your gateway can be affected by this policy and that student devices with cellular data plans will still have access?
