1 Data for 2013-14 were collected using the Fast Response Survey System, while data for earlier years were collected using the School Survey on Crime and Safety (SSOCS). The 2013-14 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 change in survey administration may have impacted 2013-14 results.
2 Does not include random dog sniffs.
3 For example, a system for reporting threats through online submission, telephone hotline, or written submission via drop box.
NOTE: Responses were provided by the principal or the person most knowledgeable about crime and safety issues at the school.
