Teachers are not allowed to physically punish students in their care. Legal disciplinary methods include removal of privileges, extra homework or detention. Parents or guardians are advised in advance if a child is given detention, as this will require the child to stay at school for a specified time after the end of the standard school day.
For serious offences, students may be suspended from school for a period of time. If they are over 16, they can be expelled permanently. Expulsion generally occurs when a student's conduct either sets a dangerous example to other students or threatens their safety. There are formal procedures for suspending or expelling a student.
