Due to the need for beginning teachers to deliver impactful instruction, the education community has widened induction initiatives that support the continued growth of new teachers. Understanding how induction mentors use their expertise to guide professional growth and development of new teachers is vital to efforts to support effective induction. This qualitative case study explored the perceived influence that servant leader attributes (Greenleaf, 1977; Spears, 2004) displayed by mentors have on beginning teachers' professional growth and development. A servant leader is defined as a leader who puts the needs, desires, and interest of others above his or her own (Greenleaf, 1977; Spears, 2004). Spears operationalized Greenleaf's original servant leadership model to include traits such as listening, empathy, healing, awareness, persuasion, conceptualization, stewardship, commitment to the growth of others, and building community. A qualitative case study approach was used to understand participants' perceptions and experiences with mentoring in relation to servant leadership. The data sources for the study consisted of interviews of new teachers and focus groups with mentor teachers. Purposeful sampling was utilized to select study participants (Creswell, 2012) in order to include as many mentor-mentee pairings as possible. Servant leadership qualities and teacher professional growth and development were explored utilizing interviews and focus groups. Thematic analysis was used to interpret the data. The study revealed seven mentor qualities that aligned to six of the servant leader attributes (Greenleaf, 1977; Spears, 2004), which were perceived by participants as playing a salient role in the mentoring process, ultimately influencing the new teachers' professional growth and development. The identification and alignment of these traits may inform the recruitment, selection, and pairing of the mentor/mentee and ameliorate influences that are not focused on the needs of the beginning teacher.
