!Interpret data with caution. The standard error for this estimate is from 30 percent to 50 percent of the estimate’s value.
‡Reporting standards not met. The standard error represents more than 50 percent of the estimate.
1Firearm or explosive device was defined for respondents as "any weapon that is designed to (or may readily be converted to) expel a projectile by the action of an explosive. This includes guns, bombs, grenades, mines, rockets, missiles, pipe bombs, or similar devices designed to explode and capable of causing bodily harm or property damage."
2Specialized school was defined for respondents as "a school that is specifically for students who were referred for disciplinary reasons, although the school may also have students who were referred for other reasons. The school may be at the same location as your school."
3Other disciplinary actions include suspension less than 5 days, detention, etc.
4Respondents 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."
5Student-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.
6Respondents were asked, "How many classroom changes do most students make in a typical day?" Responses exclude morning arrival and afternoon departure.
7Respondents were asked, "During the 2009–10 school year, did you have any security guards, security personnel, or sworn law enforcement officers present at your school at least once a week?"
8Serious discipline problems include student racial/ethnic tensions, student bullying, student sexual harassment of other students, student verbal abuse of teachers, widespread disorder in classrooms, student acts of disrespect for teachers other than verbal abuse, gang activities, and cult or extremist group 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.
9Transfers 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.
10Schoolwide 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.
11Violent incidents include rape or attempted rape, sexual battery other than rape, physical attack or fight with or without a weapon, threat of physical attack with or without a weapon, and robbery with or without a weapon.
12Rounds to 100.
NOTE: "At school" was defined for respondents to include activities that happen in school buildings, on school grounds, on school buses, and at places that hold school-sponsored events or activities. Detail may not sum to totals because of rounding. The number of incidents, students, or disciplinary actions reported for a specified offense will not always be equal. This may be because a single incident could involve multiple students or because no disciplinary action is taken for an incident. Responses were provided by the principal or the person most knowledgeable about crime and safety issues at the school.
