Many students experience difficulties during their graduate education. Scholars have proposed mentoring as one potential strategy to support them. While often assumed to be the sole responsibility of faculty, graduate students are also in a position to provide meaningful mentorship to their peers. Thus, the purpose of the current article is to focus on the relationship between peer mentor and mentee and provide those interested in becoming peer mentors during their graduate training with a guide to deliberately structure their interactions and relationships with mentees. More specifically, the approaches of four former peer mentors are presented. These are all grounded in theory and have been labeled: (a) "autonomy-supportive mentoring," (b) "mentoring with resonance," (c) "community-based mentoring," and (d) "self-concept-based mentoring."
