Incidentally you can just leave your phone at home, or turn it off.

Do they get a push notification if you turn it off?

My first thought was "leave it in your locker". Though there are separate security concerns with that.

They can still get the last location collected before the phone was powered down.

Also, now days a teenager without a phone, might as well be at home.
