A hall monitor is a student volunteer who is charged with maintaining order in a school's corridors. They may be either students who are chosen for the position because they are responsible, or that may be chosen on a rota from all available students.While specific duties vary between establishments, hall monitors typically check that students who are outside of their classrooms during lesson times have a valid
hall pass, maintain overall good conduct in the corridors by preventing running and rowdy behavior, and ensure students are punctual in attending classes. Hall monitors may also be posted to a school's doors in order to prevent unauthorized entry during recess, in which case they may be known as door monitors.
