Identifying Cost-Effective Security Barrier Technologies for K-12 Schools: An Interdisciplinary Evaluation, Arizona, 2021

This multidisciplinary study included three objectives: (1) to conduct physical security surveys of K-12 schools in Arizona to compile a dataset of the physical security barrier technologies in use in those schools; (2) to survey parents and teachers about their perceptions of security in their schools, and compare their perceptions to those of security experts who conducted physical security surveys of participating schools; and (3) to test commonly used door and window materials in schools against ballistic and forced entry attack to determine the time necessary to penetrate the material. To assess physical security, researchers visited 73 schools in 15 school districts and collected data on 3712 doors. The data collected included door material, door condition, hinges, locks, door knobs, door closers, and any windows adjacent to, or in, each door. Board certified security professionals and a retired law enforcement officer then scored the security value of each type of physical security device on a scale of 0 to 5. The scores were aggregated to arrive at an overall security score for each school that was compared to the survey responses of stakeholders. Commonly used door and window materials used in schools were also tested against ballistic and force entry attacks to establish baseline penetration times. The Penetration Test Protocols is available to download as study documentation, but the completed test report is not available with this collection. Parent perceptions were assessed using a 45 item survey. Data were collected from 614 parents or guardians who had at least one child attending one of 43 K-12 schools in 9 Arizona school districts. Most parent respondents self-identified as females (n = 401; 94 missing data points). The average parent respondent age was 43.64 (SD = 8.70), with an age range from 23 to 78 years old (113 missing data points). Parent respondents identified as White, non-Hispanic (66 percent), Hispanic (10.3 percent), Black or African American (.5 percent), American Indian (4.6 percent), Asian (.7 percent), and Native Hawaiian or Pacific Islander (.2 percent; 110 missing data points). Teacher perceptions were assessed using a 47 item survey. Data were collected from 384 teachers who taught at one of 43 K-12 schools in 8 Arizona school districts. Most teacher respondents self-identified as females (n = 292; 6 missing data points). The average teacher age was 45.38 (SD = 12.77), with an age range from 22 to 100 years old (39 missing data points). Teacher respondents identified as White, non-Hispanic (84.4 percent), Hispanic (7.8 percent), Black or African American (.5 percent), American Indian (1 percent), Asian (.3 percent), and Native Hawaiian or Pacific Islander (.3 percent; 18 missing data points). The participants' reported an average job tenure of 7.12 years (SD = 6.65), with a range from .17 to 40 years at their school (26 missing data points).
