Student Rights & Responsibilities
Conduct Off School Grounds

Students do not automatically leave the control of the school authorities once they leave the school grounds. It is well settled in the law that school officials have the authority to control student conduct off school grounds and outside school hours. As early as 1859, a boy, overheard to make a derogatory comment about his teacher, "Old Jack Seaver," outside of the school day and off school grounds, was disciplined the following day for his remarks. The court upheld the punishment because the boy's remarks could undermine management of the school. More recent cases have supported this position.

Even when students are engaged in school-sponsored activities after school hours, they are still subject to the authority of school officials whether or not the activity occurs on school property. In situations where the behavior was not part of a school-sponsored activity, school officials may still discipline students for out-of-school activities when that conduct may affect the safety and well-being of the student, other students, or school officials. Disciplinary action may also be considered when the activity causes damage to school property or makes management of the school more difficult.
