This learning activity equips school nurses with essential knowledge and practical tools to become effective health policy advocates within their educational settings. Through real-world scenarios and evidence-based strategies, learners explore how to transform daily clinical observations into powerful advocacy initiatives that address critical issues including mental health crises, chronic disease management, vaccination policies, and health equity challenges. The activity provides actionable frameworks for policy assessment, stakeholder engagement, data collection, and proposal development while demonstrating how advocacy efforts at school, district, and state levels can create lasting systemic changes that improve health outcomes for entire student populations. Participants will gain confidence in their role as policy advocates and develop the strategic communication and coalition-building skills necessary to influence decision-makers and secure resources that support comprehensive school health services.
