Informal mentoring had been previously identified as a vital component to leadership development and succession planning. Through a phenomenological approach, we sought to capture the lived experiences of aspiring school leaders pertaining to informal mentoring. Using open-ended questions and reflective activities, eight aspiring school leaders provided information about their experiences and characteristics of informal mentoring. Through a human science research perspective, four themes emerged from the data analysis: (a) defining informal mentoring, (b) characteristics of effective informal mentors, (c) constructive relationship, and (d) mentoring recommendations. Participants found their experiences with informal mentoring beneficial. There was a reported high level of trust between mentor and protégé and the process was flexible. Because the aspiring leaders sought to become school leaders in the near future, most were cognizant of the fact they needed to have quality mentors, but also be a mentor to new educators.
