Purpose: The overall purpose of this journal-ready dissertation was to determine the degree to which school level (i.e., elementary, middle, and high schools) and school urbanicity (i.e., city, suburb, town, and rural) were related to written safety plans (i.e., active shooter, hostage, bomb, and pandemic flu/disease threats) and drilled safety plans (i.e., evacuation, lockdown, and shelter-in-place) based on school administrator responses to a nationwide school safety survey. The first specific purpose was to ascertain the extent to which the frequencies of written school safety plans for active shooter, hostage, and bomb threats differ by school level and urbanicity. The second specific purpose was to establish the extent to which the frequencies of drilled school safety plans for evacuation, lockdown, and shelter-in-place practices differ by school level and urbanicity. The third specific purpose was to examine the extent to which written pandemic flu/disease safety plans differ by school level and urbanicity. In the third study, analyses were performed to determine if trends were present for school safety written pandemic flu/disease plans by school level and urbanicity. Method: For these quantitative analyses, a causal-comparative research design was utilized. Archival data within the public domain from the United States Department of Education National Center for Education Statistics School Survey on Crime and Safety for the 2007-2008, 2009-2010, 2015-2016, and 2017-2018 school years were obtained and analyzed. Findings: Concerning school safety for written and drilled plans by school level and urbanicity, elementary schools had statistically lower frequencies of safety plans for written active shooter, hostage, pandemic flu/disease, bomb threats, and drills for shelter-in-place in most instances than did middle and high schools for the years of study. Schools in rural settings had statistically significant results that indicated cases did exist for no safety drill performance for lockdowns and shelter-in-place for the two school years. Furthermore, statistically significant results existed for schools located within cities for written hostage, bomb, and pandemic flu/disease threat plans. In most instances, existing research literature correlated with results for the school years in question. Implications for policy and for practice, as well as recommendations for future research, were provided. [The dissertation citations contained here are published with the permission of ProQuest LLC.
