It is the position of the National Association of School Nurses (NASN) that every school-age child should have access to a registered professional school nurse (hereinafter referred to as the school nurse) who has a minimum of a baccalaureate degree in nursing from an accredited college or university and is licensed as a registered nurse through a board of nursing. These requirements constitute minimal preparation needed to practice at the entry level of school nursing (American Nurses Association [ANA] & NASN, 2017). Additionally, NASN (n.d.) supports state school nurse certification/licensure and endorses national certification of school nurses through the National Board for Certification of School Nurses. This document provides the background and rationale for NASN's position. [This position statement was initially adopted in October 2012 and was revised in January 2012, June 2016, and January 2021.]
