The concept of mentoring is important in nursing. Mentoring allows opportunities for a mentor to transfer knowledge and expertise in both theory and practice and a mentee to improve performance. This concept analysis aims to clarify the meaning of 'mentoring'. Attributes, antecedents, consequences, and a model case are presented to clarify this concept further. Review of literatures was conducted by using databases which include EBSCO, MEDLINE, and Google scholar. Findings showed that mentoring allows personal and professional growth of mentees. Closing the gap between theory and practice is achieved through an expert supervision of a mentor to a mentee. Mentoring plays a central role in the development of novice nurses as they integrate theoretical concepts into their practice. The benefits of mentoring are illuminated in the increasing competency of nurses in performing their roles to be globally competitive.
