> Quite sure that is the schools job. At least where I live the schools tend to assume several of the rights and responsibilities that normally fall on the parents.

Yes. The school is responsible for their safety and whereabouts. US K-12 public schools, if the child is missing from school, parents are contacted immediately. Teachers are responsible for attendance. All this is accomplished without device tracking. Federal law explicitly defines the school's responsibilities with regard to privacy rights of children in school. If parents wish to contact their child during school hours, they are asked to call the school, and school personnel will contact the child.

Device use is an enormous problem in schools. Talk to any teacher / admin: they will tell you allowing devices into schools has been a disaster.

The US is definitely the world, and I am definitely in that world, and the people who make that assumption are definitely super smart all around.
