 Traces of the past, questions of the present: What transformations for training engineering? 
Distancing itself from most of the works devoted to training engineering, which identify its beginnings in the 1980s, this article proposes a different interpretation, which situates the appearance of practices, methods, tools, and actors dedicated to this field in the industries of the interwar period. Training engineering is then at the service of the rationalization of production in order to train and stabilize qualified personnel. Since the 2000s, it has had to adjust to the new situation represented by the individualization of the wage relationship, which makes training and employees’ career paths a condition of their employability, thus raising the question of its transformation into an engineering designed to support individuals who are required to be autonomous and responsible.
