Results: This evaluation provided evidence that the SYHN Program is reaching students in need, is effective, has been adopted successfully in schools, is being implemented as intended and could be maintained with sustained funding. The nurses deliver an accessible and acceptable primary health care service, focused on health promotion, prevention and early intervention. After some initial uncertainty about the scope and nature of the role, the nurses are a respected source of health information in the schools, consulted on curriculum development and contributing to whole-of-school health activities.
