In this contribution, we report on an ongoing research program conducted in Geneva (Switzerland), dedicated to relationships between parents and professionals in the field of Early Childhood Education. In this research program, we aim at understanding the sorts of interactional competences mobilised by educators when encountering parents in daily work situations. The program includes a video-ethnographic survey based on direct observation of naturally occurring encounters, as well as a training program, dedicated to in-service educators in which their interactional competences can be elaborated and developed. The chapter reports on the research design of this project, presents the empirical material collected and provides an overview of the main research findings available to date.
