Abstract
School safety concerns have intensified in response to rising rates of school violence, prompting many districts to implement high-visibility security measures such as metal detectors. While these measures are intended to enhance physical safety, their effects on school climate, stakeholder perceptions, and relational dynamics remain insufficiently understood, particularly in urban middle school contexts. The purpose of this qualitative case study was to examine how stakeholders perceived the implementation of metal detectors and their influence on school climate at one urban middle school. Using Bronfenbrenner's ecological systems theory as a theoretical framework, data were collected from three administrators, eight teachers, and three parents through semi-structured interviews, a focus group, and document analysis. Data were analyzed thematically across four domains: safety, accountability, and policy compliance; emotional and relational impact; operational and implementation challenges; and communication, transparency, and equity concerns. Findings indicated that stakeholders perceived metal detectors as both necessary and disruptive, with perceptions shaped by role, proximity to students, and position within interconnected ecological systems. Administrators emphasized procedural compliance and institutional accountability, while teachers and parents highlighted emotional costs, relational strain, and operational inconsistencies that negatively influenced students' daily experiences and sense of belonging. Communication gaps and equity concerns, particularly among linguistically diverse and immigrant families, further undermined trust and engagement. These findings converged with existing literature on school climate, visible security measures, and ecological systems theory, while extending the literature by identifying operational consistency and equitable implementation as relational and climate concerns not previously well integrated. Recommendations include adopting proactive multilingual communication strategies, investing in operational reliability and staff training, integrating trauma-informed relational practices into arrival routines, creating structured opportunities for stakeholder input, and applying an equity lens to safety policy decisions. Future research should examine student perspectives, longitudinal climate effects, and implementation patterns across diverse community contexts.
