Using the hierarchy of controls to prevent gun violence in education settings

The NEA guide introduces a structured, evidence-based framework to help schools address gun violence as a workplace hazard. Adapted from occupational health practices, the hierarchy includes five levels of intervention - elimination, substitution, engineering controls, administrative controls, and personal protective equipment - prioritizing the most effective strategies first. The guide emphasizes that any measures taken must not compromise trauma-informed, culturally competent education or rely solely on "hardening" schools.
