From Institutional Policy and Practices to School Safety: The Mediating Role of School Climate

Background/Purpose: School safety is a critical concern for students, educators, and policymakers. While prior research on school safety has largely focused on individual-level risk factors among students and teachers, less attention has been paid to how institutional policy and practices shape safety outcomes, and the mechanisms through which such institutional factors operate remain largely unknown. Drawing on heuristic social-ecological model of school violence, this study aims at examining the impacts of school policy and practices on school safety through school climate. Specifically, this study explored how institutional practices including policy enforcement and school inclusion, influence school safety through the mediating pathways of violence reporting climate, teacher support, and student engagement.

Methods: A total of 1258 students from 8th and 10th grade were included in the study, with 50.0% identifying as male, 43.9% as female, and 6.0% identifying as non-binary or other gender identities. The sample was predominantly White/Caucasian (57.5%), followed by Black/African American/Caribbean American (20.1%), Native American (4.8%), Arab American/Chaldean (2.9%), Asian American (2.5%), and other racial/ethnic identities (12.0%). Structural equation modeling (SEM) was conducted in Mplus using maximum likelihood estimation. Indirect effects were estimated using bias-corrected bootstrapping with 5,000 resamples.

Results: The SEM model fit the data well, χ2 (df=358, N = 1258) = 933.564, p < 0.001, RMSEA = 0.036, CFI = 0.965, TLI = 0.961, SRMR = 0.040. Policy enforcement demonstrated a suppression effect, with a negative direct effect on school safety (β = −.141, p = .015) and a significant positive total indirect effect (β = .246, p < .001) operating through school climate. Significant indirect effects were observed through violence reporting climate (β = .077, p = .005), teacher support (β = .095, p = .002), and student engagement (β = .075, p < .001. School inclusion showed no significant direct effect on school safety (β = −.025, p = .658), yet its total indirect effect was positive and significant (β = .212, p < .001), indicating full mediation by school climate. Significant indirect effects of school inclusion were found through teacher support (β = .100, p = .002), student engagement (β = .066, p < .001), and violence reporting climate (β = .045, p = .007).

Conclusions and Implications: The results suggested that institutional practices contribute to school safety through the climate conditions they generate, rather than rely on direct impacts. The full mediation pattern for school inclusion and the suppression effect for policy enforcement both point to the same conclusion: what matters is not simply whether a school enforces rules or adopts inclusive curriculum, but whether those practices translate into a positive, responsive, and inclusive school environment. Schools seeking to enhance safety should prioritize building strong teacher-student relationships, fostering student engagement, and cultivating a reporting culture where students feel comfortable disclosing victimization. Practitioners and administrators should view policy design and inclusive curriculum not as ends in themselves, but as structural levers for shaping the daily climate students experience.
