In order to meet changing global population needs and consumer expectations, healthcare systems worldwide are under transformation and face restructuring. As systems adapt and shift their emphasis in response to the disparate requests for healthcare services, oppor-tunities emerge for nurses, especially the APN, to meet these demands and unmet needs (Bryant-Lukosius et al. 2017; Carryer et al. 2018; Cassiani & Zug 2014; Cooper & Docherty 2018; Hill et al. 2017; Maier et al.2017). In 2002, the International Council of Nurses (ICN) pro-vided an official position on Advanced Practice Nursing (ICN 2008a). Since that time, worldwide development has increased significantly and simultaneously this field of nursing has matured. ICN felt that a review of its position was needed to assess the relevance of the definition and characteristics offered in 2002. This guid-ance paper defines diverse elements such as assump-tions and core components of the APN. The attributes and descriptors presented in this paper are intended to promote a common vision to continue to enable a greater understanding by the international nursing and healthcare communities for the development of roles commonly identified as Clinical Nurse Specialist (CNS) and Nurse Practitioner (NP).
