In an in-house third-year social work research placement, a duo-ethnography showed that the student--supervisor relationship had far more impact on transformative learning than the assigned placement tasks. A model for co-creating an environment of transformative learning is described, putting student learning and growth at the center. Attributes that contributed to a transformative learning environment included being Trustworthy, Respectful, Engaging, Caring, and Humble. A range of actions within each of these attributes is described. The findings showed that in this context, a crisis-type of disorienting dilemma did not occur. Rather, transformation evolved as part of a learning outcome that included the development of a professional identity as a social worker. Findings suggested the need for further exploration of the role that humility plays in reducing the power imbalance in the student--supervisor relationship. The importance of addressing self-care and avoiding models that risk perpetuating patriarchy in the student-supervisor relationship were highlighted.
