Background: Healthy students are better learners is central to the K-12 education mission to graduate students successfully. School nurses support students' educational success by taking care of their immediate health needs, coordinating care for students' chronic health conditions, and promoting healthy behaviors. This study uses a knowledge, motivation, and organizational gap analysis framework to evaluate how Connecticut school nurses perceive their role and practice in the educational environment are valued to further the educational mission. Methods: A qualitative phenomenological design was used. Fourteen Connecticut school nurses were interviewed via Zoom in January 2021. Data from interviews was analyzed using thematic analysis. Results: Although school nurses believe that they bring value to students by providing equitable access to healthcare and wellness education, they felt that the organization did not recognize how indispensable they are to meeting the educational mission. School nurses identified four areas of opportunity: advocacy skills that enables the organization to recognize the alignment of the school nurse expertise with the educational mission; belief in their ability to advocate to change workload levels to ensure the provision of safe healthcare; and an advocacy platform within the organization to convey their value as essential to the educational mission. Recommendations: Empower school nurses to advocate how and why their role is indispensable to the K-12 educational mission.
