It is the position of the National Association of School Nurses (NASN) that the registered professional school nurse (hereinafter referred to as school nurse) is a crucial member of the team participating in the prevention of bullying in schools. School nurses are the experts in pediatric health in schools and, therefore, can have an impact on the health and safety of all students including students who bully; students who are bullied; or students who both bully and are bullied by others (Centers for Disease Control and Prevention [CDC], 2011a, 2011b). The school nurse role includes the prevention of bullying and the identification of students who are bullied, bully others, or both. The school nurse has a significant leadership role in the implementation of bullying prevention policies and strategies.
