Anecdotal reports of the protective qualities of mentoring relationships for youth are corroborated by a growing body of research. What is missing, however, is research on the processes by which mentors influence developmental outcomes. In this article, we present a conceptual model of the mentoring process along with a delineation of some of the current research on what makes for more effective mentoring relationships. A set of recommendations for future research is offered. © 2006 Wiley Periodicals, Inc.
