Both Deerfield High School and Highland Park High School are closed campuses. Students must remain on campus during the school day until classes end for the day. Students are not to leave campus during their school day without proper authorization. If a student is found outside the building without a pass the student shall be considered to be attempting to leave campus without proper authorization. They will be brought to the Deans' Office. Students and their possessions may be searched upon re-entry.
Students who need to leave campus for any reason after they enter school, or wish to retrieve items from their car must obtain a pass from the Deans' Office to do so. Leaving campus without authorization will result in consequences including, but not limited to, Saturday detentions, alternative in-school settings, and loss of parking privileges.
During final exams, each campus is open due to an alternative schedule for students.
