Do teachers have the right to publicly ask students the cuase of their disclipline? include cited information

Umm I don't think thats the correct way to ask that question but, if that is than Teachers can ask the student if he/she is getting beat at home, or actions at home that reflect on them at school. But to say "cause of discipline"  isn't really their business. Whatever that child got disciplined for is between the child the illegal guardian. But if the child seems to be bruised, and badly beaten than the teacher has the rights to call authority, or contact DFCS. (Division of Family and Children Services)
