School nurses (SNs) use public health nursing knowledge and skills to provide nursing services to school populations. The Public Health Intervention Wheel is a practice framework that can be used to explain and guide public health nursing interventions. SNs who were also members of the National Association of School Nurses completed an electronic survey on their use of public health interventions as defined by the wheel. Although 67% of the participants were not familiar with the Public Health Intervention Wheel, respondents reported conducting activities that were consistent with the Wheel interventions. Screening, referral and follow-up, case management, and health teaching were the most frequently performed interventions. Intervention use varied by educational level, age of nurse, years of practice, and student population. The Public Health Intervention Wheel is a relevant and useful framework that provides a language to explain population-based school nursing practice.
