One of the most concerning findings from investigations into numerous school shootings is how perpetrators have gained access to school buildings by shooting through glass entrances, sidelights, or windows adjacent to secured doors.
In the thousands of school safety assessments our teams at the School Safety Advocacy Council have conducted across the country, the vulnerability of non-fortified glass entrances has consistently been identified as a significant security concern.
Unfortunately, we continue to see a troubling trend in modern school construction. Many school districts are relying on architects who encourage the extensive use of glass in both exterior entrances and interior spaces. Their justification often centers on allowing more natural light into classrooms, creating a more inviting learning environment, and potentially improving student creativity, academic performance, and test scores.
While these are certainly worthwhile educational objectives, what is too often overlooked is the potential security vulnerability created when extensive glass is incorporated into school designs without adequate protective measures.
Over the past decade, our assessment teams have witnessed a growing number of newly constructed schools featuring expansive glass entrances, walls, and interior spaces. These design decisions can create significant challenges when attempting to maximize the safety and security of students, teachers, and staff.
In many cases, our teams recommend the strategic use of tested security glazing systems or security window film as part of a comprehensive approach to strengthening vulnerable areas. However, window film alone does not make glass bulletproof or prevent every form of forced entry. Proper installation, anchoring, and the overall glazing system are critical considerations. Retrofitting these vulnerabilities after construction can also become extremely costly for school districts.
The larger question is why we continue designing and constructing schools with preventable security vulnerabilities, only to spend significant taxpayer dollars attempting to correct those weaknesses years later.
I am certainly not suggesting that schools should resemble correctional facilities or that natural light and inviting learning environments are unimportant. Quite the opposite. I believe architects, educators, and school safety professionals must work collaboratively from the earliest stages of school design to achieve both objectives.
School safety should never be an afterthought in architectural design. It must be a fundamental part of the design process from day one.
We can build beautiful, welcoming, innovative schools without sacrificing the safety of the children and educators who occupy them every day.
