The supervision and mentoring of pre-service teachers during professional experience is complex work that requires a range of skills and capacities. Professional development for this work has traditionally been limited, however, and mentor teachers report experiencing tensions in their work stemming from their roles as both supporter and assessor of pre-service teachers. Despite the central role that mentors play in professional experience, their voices are underrepresented in the literature. In this paper, I draw on interview data to examine teachers' experiences as mentors and the tensions they experience. I use poetic representation to illuminate the tensions and emotions of mentoring and present seven poems that provide insight into these tensions. I argue that poetic representation of interview data provides an opportunity to connect with the experience of being a mentor and offer suggestions for teacher educators to work collaboratively with mentor teachers to explore the dimensions of their role.
