1 Data for 2013-14 were collected using the Fast Response Survey System (FRSS), while data for all other years were collected using the School Survey on Crime and Safety (SSOCS). The 2013-14 FRSS survey was designed to allow comparisons with SSOCS data. However, respondents to the 2013-14 survey could choose either to complete the survey on paper (and mail it back) or to complete the survey online, whereas respondents to SSOCS did not have the option of completing the survey online. The 2013-14 survey also relied on a smaller sample. The smaller sample size and difference in survey administration may have impacted the 2013-14 results.
2 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. Separate data on high schools and combined schools are not available for 2013-14.
3 Because the 2013-14 survey did not collect data on the percentage of students eligible for free or reduced-price lunch, the classification of schools by the percentage of eligible students was computed based on data obtained from the Common Core of Data.
NOTE: Security staff include security guards, security personnel, School Resource Officers (SROs), and sworn law enforcement officers who are not SROs. "Security guards" and "security personnel" do not include law enforcement. SROs include all career law enforcement officers with arrest authority who have specialized training and are assigned to work in collaboration with school organizations. Responses were provided by the principal or the person most knowledgeable about crime and safety issues at the school.
