! 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 for this estimate is equal to 50 percent or more of the estimate's value.
1 Data represent the mean number of "yes" responses to the practices listed.
2 Examples of controlled access to school buildings provided to respondents were locked or monitored doors.
3 Examples of controlled access to school grounds provided to respondents were locked or monitored gates.
4 Respondents 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."
5 Responding schools that did not have race/ethnicity on the sampling frame (2 percent of schools) are excluded from the base.
6 Student-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.
7 Respondents were asked, "How many classroom changes do most students make in a typical day?" Responses exclude morning arrival and afternoon departure.
8 Respondents were asked, "During the 2005–2006 school year, did you have any sworn law enforcement officers, security guards, or security personnel present at your school at least once a week?"
9 Serious discipline problems include student racial tensions, student bullying, student sexual harassment of other students, student verbal abuse of teachers, widespread disorder in classrooms, student acts of disrespect for teachers, 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.
10 Transfers 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.
11 Schoolwide 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.
12 Violent 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.
NOTE: Responses were provided by the principal or the person most knowledgeable about crime and safety issues at the school. Detail may not sum to totals, because schools may have reported using more than one of these practices. 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.
