Patterned after Strunk and White's classic The Elements of Style, this short reference concisely summarizes the substantial existing research on the art and science of mentoring. Although there are a number of successful books addressing mentoring, this book reduces the wealth of published theory on the topic to the fifty most salient and pithy truths for supervisors in all fields. The book is arranged into six parts, which clearly organize these key elements of successful mentoring: 1) What Excellent Mentors Do, 2) Traits of Excellent Mentors, 3) Arranging the Mentor Protege Relationship, 4) Mentoring and Integrity, 5) When Things Go Wrong, and 6)Welcoming Change and Saying Good bye.
