1 In 2015-16, this question was significantly revised. Comparisons with earlier years are not possible. Readers should refer to previous versions of the report for time series data on schools drilling students on the use of a plan in selected crises.

2 On the 2015-16 questionnaire, the wording was changed from "Shootings" to "Active shooter."

3 For example, earthquakes or tornadoes.

4 For example, release of mustard gas, anthrax, smallpox, or radioactive materials.

5 In 2007-08 and 2009-10, schools were asked whether they had a plan for procedures to be performed if the U.S. national threat level were changed to Red (Severe Risk of Terrorist Attack) by the Department of Homeland Security. In 2013-14, schools were asked whether they had a plan for procedures to be performed if an "imminent threat alert" were issued by the Department of Homeland Security's National Terrorism Advisory System. Data on severe risk of terrorist attack were not collected in 2015-16.

6 Defined for respondents as "a procedure that requires all students and staff to leave the building. While evacuating to the school’s field makes sense for a fire drill that only lasts a few minutes, it may not be an appropriate location for a longer period of time. The evacuation plan should encompass relocation procedures and include backup buildings to serve as emergency shelters, such as nearby community centers, religious institutions, businesses, or other schools. Evacuation also includes 'reverse evacuation,' a procedure for schools to return students to the building quickly if an incident occurs while students are outside."

7 Defined for respondents as "a procedure that involves occupants of a school building being directed to remain confined to a room or area within a building with specific procedures to follow. A lockdown may be used when a crisis occurs outside of the school and an evacuation would be dangerous. A lockdown may also be called for when there is a crisis inside and movement within the school will put students in jeopardy. All exterior doors are locked and students and staff stay in their classrooms."

8 Defined for respondents as "a procedure similar to a lockdown in that the occupants are to remain on the premises; however, shelter-in-place is designed to use a facility and its indoor atmosphere to temporarily separate people from a hazardous outdoor environment. Everyone would be brought indoors and building personnel would close all windows and doors and shut down the heating, ventilation, and air conditioning system (HVAC). This would create a neutral pressure in the building, meaning the contaminated air would not be drawn into the building."

9 Data on suicide threat or incident, severe risk of terrorist attack, and pandemic flu were not collected in 2003-04 and 2005-06.

10 Data on post-crisis reunification of students with their families were not collected in years prior to 2015-16.

11 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.

12 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.

13 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 students eligible for free or reduced-price lunch was computed based on data obtained from the Common Core of Data.

14 Separate data for students of Two or more races were reported only for 2015-16.

NOTE: Responses were provided by the principal or the person most knowledgeable about crime and safety issues at the school.
