School nurses are unable to audit each individual child's immunization record due to the large number of students and schools. School nurses serve as the district's local immunization expert. Nurses need to understand and be familiar with school entrance requirements, updates, and basic information regarding vaccinations. Nurses should also have a working knowledge of local clinics where children can obtain immunizations. They can also facilitate cases of noncompliance and enforce the state law of exclusion when necessary. School nurses also help to conduct trainings and guide communication with schools about the required reports that need to be submitted regarding immunizations. Lastly, school nurses can offer additional information about supplemental vaccinations needed in their district such as flu shots. More information about immunizations can be found at the Immunization Program website.
