Due to new regulations and mandates, so-called "evaluation" models and practices are proliferating in the professional sphere. Their introduction into the health, social services, and education sectors is raising questions among practitioners and sparking controversy regarding their purpose and impact. In the context of my work as a trainer and consultant, the proposal to open up spaces for reflection on "The Evaluation of Training Activities" while simultaneously generating significant interest met with considerable resistance. This dual dynamic led me to question the fascination aroused by the representations and connotations associated with this concept. This work explores, through a reflexive analysis, what unfolded during these encounters. Building on this reconsideration, drawing on philosophical concepts and those from work analysis, I broadened my perspective to define and understand the challenges of this "culture" of evaluation at the institutional and individual levels, ultimately exploring how supporting an evaluation process can constitute an organizational intervention and under what conditions it can be conceived as a professionalizing practice.
