Historically, there has been a lack of emphasis in the nursing profession on being mentored or on mentoring others. As the business world has known for years, the benefits of mentoring for mentees include having a definitive career plan, increased job satisfaction, improved socialization to the role, higher levels of self-esteem and confidence, higher salaries, and more opportunity for advancement (Grindell, 2003; Harrington, 2011; Tracy, 2012). Although new nursing professionals are often “precepted” by a more experienced nurse, these novice providers are frequently expected to practice on their own after the specified orientation period is over. Nurse practitioner graduates may or may not have a period of orientation with a preceptor, depending on the practice site. Various terms have been used to describe those who assist others as they develop and learn professionally. Common terms are preceptor, teacher, educator, guide, coach, manager, role model, and mentor. Oftentimes, these terms are used interchangeably, which adds to confusion about the roles. What defines these roles will be reviewed in this chapter with the focus on the mentor.
