Usually the parents go to court if dissatisfied with the decision of the school administrators or the independent body.
For example, a student who has committed an infraction of failure and refusal to wear the proper uniform at school must first be given written notice informing him that there is a school policy requiring students to wear school uniform and that the student has violated this school policy.
He will thereby be informed that there will be hearing to determine whether he indeed has violated the school policy.
The second goal of due process in educational institutions is to assure the students that before the decision was reached, the students were heard and that they were treated fairly b school administrators.
It seeks to give the appearance of fairness in the procedures involved before the decision was reached.
