While medical experts establish the clinical standard of care for emergency response, a school safety or risk management expert plays a distinct and complementary role by addressing the institutional context: what training programs, equipment standards, and emergency protocols are considered reasonable and standard practice for schools of a similar size and resource level, and how the specific district's actual practices compared. This testimony helps translate a purely clinical standard of care into an institutional framework that speaks directly to the district's own policy decisions and resource allocation, which is often central to establishing breach.
