Hope, I don’t understand your question: “Is there a law that permits a teacher from telling another parent about another student that they are on a IEP?” Did you mean to ask “is there a law that forbids a teacher …?”
A teacher should not tell a parent that another child is on an IEP. A teacher should not discuss other students with parents.

A teacher should not tell a parent that another child is on an IEP. A teacher should not discuss other students with parents.
No teacher should ever talk about another child to a parent.
