The aim of this study was to describe the diverse experiences of early childhood student teachers and mentors during the teaching practicum over the period of one semester, and trace power aspects within the relationship of 20 dyads. Data collection included repeated entries within a reflective journal, following specific guiding questions. The data were analysed using patterns of common reference to relationship issues. Findings of the study identified trends of power which present a powerful mentor and an empowered student teacher in relation to practicum issues. Both parties exhibited powerful behaviour in different situations, suggesting that a healthy professional relationship allows for parallel contribution. Thus, when considering teaching practicum for student teachers and programmes for mentors, an elaborated discussion on the diverse facets of power should take place. (Contains 1 table.)
