In many countries, strategies to further develop services and institutions for the education and care of young children are linked to a discourse on professionalism. Ambitious policy goals, it is argued, can only be achieved by a skilled and qualified workforce whose practice is guided by a professional body of knowledge. This article argues that the prevailing conceptualisation of the early childhood professional is constructed out of a particular, hierarchical mode of producing and applying expert knowledge that is not necessarily appropriate to professional practice in the field of early childhood education. However, it is highly effective and contributes to forming a professional habitus that contradicts the relational core of early childhood practice. Drawing on the conceptual framework of hermeneutics, the article explores an alternative paradigm of a relational, systemic professionalism that embraces openness and uncertainty, and encourages co-construction of professional knowledges and practices. Research, in this frame of thinking, is understood as a dialogic activity of asking critical questions and creating understandings across differences, rather than producing evidence to direct practice.
