Alumni who are veteran teachers can become a valuable resource for teacher education programs in mentoring beginning teachers from the same institution. An Alumni Mentoring Guild was established through a School of Education and Office of Career Services to bring back alumni to help beginning teachers. Mentors worked with up to three beginning teachers or new graduates for a year to guide them with the challenges of teaching. A self-efficacy questionnaire, narrative responses, and a contact log were used to assess the program. Recommendations for developing an alumni mentoring program focus on collaboration, recruitment, administrative oversight, participant feedback and improvement of a teacher education program.
