Learning to work as a relational caring professional in healthcare and social welfare, is foremost a process of transformative learning, of Building, of professional subjectification. In this article we contribute to the design of such a process of formation by presenting a structured map of five domains of formational goals. It is mainly informed by many years of care-ethical research and training of professionals in healthcare and social work. The five formational domains are: Relational Caring Approach, Perception, Knowledge, Interpretation, and Practical Wisdom. The formation process, described as the recurring detour of a continuing practice, requires ‘exposure’, in-depth learning and learning communities. Relational caring—care consequently resulting from and structured by relational thinking, exploring, and steering—requires ‘inquiry’ as a continuous learning process in practice. The process is ultimately aimed at fostering mature, competent, and practically wise professional caregivers who are able to relationally connect with and attune to care receivers, and adequately navigate existential, moral, and political-institutional tensions in relational caring in complex organizations in Late-Modern society.
