A positive correlation exists between closed campuses and academic achievement and higher grade-point averages. More students participate in intramural programs, student activities, and have a higher level of school spirit. School staff has a better understanding of their students from the increased contact and participation. Students often enjoy improved food selection and preparation, especially when the district's food service program responds more to students' food choices. Fewer daytime residential burglaries and other incidents of crime occur in communities surrounding the school campus.
Relationships improve with local law enforcement.
Law enforcement agencies report less investigation calls to neighborhoods surrounding campuses and they do not need to schedule extra officers to work during the school's lunchtime to respond to community calls. Closed campuses enjoy improved relationships with their communities. There are fewer complaints from neighboring businesses and residential communities about students loitering, littering, or fighting off-campus. Some businesses report increased sales because customers are no longer fearful of large numbers of youth congregated at the businesses. Closed campus policies eliminate the majority of foot and automobile traffic off campus during the school day, and school staff can more easily monitor outsiders who enter the school campus.
