Student acuity and school community indicators should be assessed to determine appropriate staffing levels. Access to a school nurse may mean that more than one school nurse is necessary to meet the needs of the school population. School nurse workloads should be evaluated on at least an annual basis to meet the health and safety needs of school communities (Jameson et al., 2018).
