  • Nearly 6% of high school students in 2007 reported taking a gun, knife, or club to school in the 30 days before the survey
  • 27.1% of students reported having property stolen or deliberately damaged on school property.
  • 5.5% did not go to school on one or more days in the 30 days preceding the survey because they felt unsafe at school or on their way to or from school.
  • 7.8% reported being threatened or injured with a weapon on school property one or more times in the 12 months preceding the survey
  • During the past seven years, 116 students were killed in 109 separate incidents—an average of 16.5 student homicides each year
