Some of those rights are restricted a bit when one is at school. For example, a school may impose limits on the type of article chosen for publication in a school-run newspaper. Schools may also limit the expression of offensive speech and can set up a dress code. School personnel or the police may not search a student, or a student's car / backpack / purse / locker without a legally sufficient reason or a search warrant. One example of a legally sufficient reason would be a report that a student was seen on the school grounds with contraband (drugs or a weapon) in the student's possession. If the school searches a locker and finds contraband, but a court finds the school didn't have a legal reason for the search, any criminal charges for that offense could be dismissed or the evidence suppressed (thrown out of court).

Schools can set up rules and policies that outline the disciplinary system. For a school rule to be enforceable, it should be in the school's policy manual, and the school must distribute the manual to students. The best way to find out what your school's policies and rules are is to get a copy of the school's policy manual. You can request a copy from the administrative office at the school.
