This paper focuses on the social representations of the professions of Conseiller principal d’éducation and Secondary school teacher, within the context of the division of labour instituted in secondary schools, among students in their first year of a Master’s degree. Our corpus is a survey through a questionnaire administered upon entering initial training in the academic territories of Aix-Marseille, Lille, Nantes and Rennes. The results highlight the paradoxical finding that the CPE, if s/he is no longer perceived to be a head supervisor or proctor, is nonetheless identified as the law and order expert despite an evolution in recognition for the profession, in particular for its role in guiding the development of pupils and that of managing the supervisory team in the school. The definitions of the jobs more or less converge but the projection onto the professional field indicates that collaborative work is an idea either rarely shared, or rarely imagined.
