!Interpret data with caution. The coefficient of variation (CV) for this estimate is between 30 and 50 percent.

1 Primary 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.

2 Student/teacher ratio was calculated by dividing the total number of students enrolled in the school, as reported on the School Survey on Crime and Safety (SSOCS), by the total number of full-time-equivalent (FTE) teachers. Information regarding the total number of FTE teachers was obtained from the Common Core of Data (CCD), the sampling frame for SSOCS.

3 "Violent incidents" include rape or attempted rape, sexual assault other than rape, physical attack or fight with or without a weapon, threat of physical attack or fight with or without a weapon, and robbery with or without a weapon. "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. Respondents were instructed to include violent incidents that occurred before, during, or after normal school hours or when school activities or events were in session.

NOTE: Includes schools reporting that cyberbullying happens either "daily" or "at least once a week." "Cyberbullying" was defined for respondents as occurring "when willful and repeated harm is inflicted through the use of computers, cell phones, or other electronic devices." Responses were provided by the principal or the person most knowledgeable about crime and safety issues at the school. Respondents were instructed to include cyberbullying "problems that can occur anywhere (both at your school and away from school)."
