Are students families aware of this?

That's kind of scary because kids are learning to be policed from a young age. Might be easier to convince them in the future that it's an acceptable behavior to be officially profiled by third parties. Even if this third party is a school teacher, it's absolutely NOT okay.

I understand the eagerness to monitor and try to help the student as much as possible, but a teacher or a school committee should understand the repercussions of this kind of monitoring, no matter what the results are.
