The purpose of this study was to compare two different formal mentoring relationships based on the perceptions of beginning teachers regarding their dyadic interactions. Kram's mentor role theory and Byrne's similarity-attraction paradigm served as the theoretical foundation for the study. The specific variables of interest included psychosocial mentoring, dyad similarity, and dyad satisfaction. The time and place sample consisted of beginning agricultural education teachers (n = 40) paired with a mentor in the school where they taught (i.e., in-school), and beginning agricultural education teachers (n = 40) paired with an agricultural education mentor located in a neighboring school (i.e., in-profession). Data for this study were collected by using the Mentoring Relationship Questionnaire (MRQ). No statistically significant differences were found between the two mentoring relationships. Recommendations for further investigation are suggested, including the need to expand the understanding of relationship dynamics and predictors of quality mentoring.
