Then Mom can take her little angel elsewhere.
If the school is actually going to be In Loco Parentis, or whatever the legal term is, then they should have the right to discipline with corporal punishment wherever that is allowed by law.
“Then Mom can take her little angel elsewhere.”
That’s the problem - the school can’t make her but she can make them. Apparently short of murder (or drawing a picture of a firearm) you can’t expell a student these days.
