1Examples of contraband provided to respondents were drugs or weapons.
2Primary schools are defined as schools in which the lowest grade is not higher than grade 3 and the highest grade is not higher than grade 8. Middle schools are defined as schools in which the lowest grade is not lower than grade 4 and the highest grade is not higher than grade 9. High schools are defined as schools in which the lowest grade is not lower than grade 9 and the highest grade is not higher than grade 12. Combined schools include all other combinations of grades, including K–12 schools.
3Respondents were asked, "How would you describe the crime level in the area(s) in which your students live?" Response options included "high level of crime," "moderate level of crime," "low level of crime," and "students come from areas with very different levels of crime."
4Student-to-FTE ratio was calculated by dividing the total number of students enrolled in the school by the total number of full-time-equivalent teachers and aides. The total number of full-time-equivalent teachers and aides is a combination of the full-time and part-time teachers and aides, including special education teachers and aides, with an adjustment to compensate for the part-time status.
5Respondents were asked, "How many classroom changes do most students make in a typical day?" Responses exclude morning arrival and afternoon departure.
6Regular use of security staff includes full- or part-time school resource officers, sworn law enforcement officers, or security guards or security personnel present at school at least once a week.
7Serious discipline problems include student racial/ethnic tensions, student bullying, student sexual harassment of other students, student harassment of other students based on sexual orientation, student harassment of other students based on gender identity, widespread disorder in classrooms, student verbal abuse of teachers, student acts of disrespect for teachers other than verbal abuse, and gang activities. If a respondent reported that any of these problems occurred daily or weekly in their school, each was counted once in the total number of serious discipline problems.
8Transfers as a percentage of enrollment combines the number of students who were transferred to a school and the number of students who were transferred from a school divided by the total number of students enrolled in the school.
9Schoolwide disruptions include actions that disrupted school activities such as death threats, bomb threats, and chemical, biological, or radiological threats. Respondents were instructed to exclude all fire alarms, including false alarms.
10Violent incidents include rape or attempted rape, sexual assault other than rape (including threatened rape), physical attack or fight with or without a weapon, threat of physical attack with or without a weapon, and robbery (taking things with force) with or without a weapon.
NOTE: Detail may not sum to totals because schools may have reported using more than one of these practices. Responses were provided by the principal or the person most knowledgeable about crime and safety issues at the school.
