Green Valley High School operates under a closed campus policy. After arriving at school, the student is not to leave school either during class, at lunch, or between periods without a passport. Students may not leave the building to go to the parking lot. Passports for appointments, illness, or any justifiable reason may be obtained with parental permission in the attendance office. Students may not leave campus at lunch or have lunch brought to them on campus. In addition, if students are ill, all phone calls to parents/guardians must be made from the Health Office.
