| 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.

| NOTE: Responses were provided by the principal or the person most knowledgeable about crime and safety issues at the school. Serious disciplinary actions include removals with no continuing services for at least the remainder of the school year, transfers to specialized schools for disciplinary reasons, and out-of-school suspensions lasting 5 or more days, but less than the remainder of the school year. Respondents were instructed to respond only for those times that were during normal school hours or when school activities or events were in session, unless the survey specified otherwise. Detail may not sum to total because schools could report more than one type of offense, but were only counted once in the total. |
