School nurses across Massachusetts and the nation rose to the challenges presented by the pandemic of the coronavirus disease 2019 (COVID-19). One of the many ways in which school nurses responded to the pandemic was to work in collaboration with their Local Boards of Health in a variety of capacities. The essential functions of a school nurse uniquely prepare them for the roles of case investigators and contact tracing monitors as a means to ensure population health. In addition to both individual and population health within the school setting, school nurses are effective partner in emergency planning and can help inform decision making and policy making within communities.
