This paper, pertaining to the education sciences and using a psycho-sociological methodology, addresses the profession of Conseiller principal d’éducation, or senior educational counsellor. A structural approach is used to understand the existence of a consensual professional representation of the profession, detailing its content and its internal organisation. Given the variety of practices and a confused professional identity, what we have been able to highlight as the core of the profession, both central and normative, is counselling and listening. Functional and circumstantial elements for their part refer to an administrative and disciplinary representation of the job as well as to an ethical and reflexive one. It is listening skills, according to the analysis in similarities, which federates the representatives of the profession around an organisational and reflexive order linked to counselling and educational values, and around a sphere of action linked to adaptability and availability.
