Why are preschool name tags necessary?

I think it is more for the teachers and staff to know who the children are than the children themselves, as well as any parents coming to the preschool.

Another reason could be, God forbid, if a child wonders off people know who the child is and where he or she could be.

Does anyone know if it is a law preschools use name tags?
