The authors deal with the topic of training in group and institutional settings with specific attention to how these interventions can be conceived and implemented in the current social situation. The reflections move from a conceptual and operational reference scheme based on the operational psychoanalysis of E. Pichon-Rivière and J. Bleger for conceptualization and intervention through group devices and in the contexts of care institutions. The cultural dimension is considered as an aspect that characterizes many contexts of training work in the current psycho-social-health and educational services. The attitude and ability to welcome change on the part of operators is highlighted as a current necessity in training work. This presupposes knowing how to integrate and evolve the reference schemes through which group and institutional training interventions operate. The proposed reflection also takes into account some movements that are found today in the community context, in the Polis within which training processes involving groups and institutions take place. Thus the consideration arises that training has taken on, even more so in recent years, a role of welcoming the subjective, intersubjective, group and institutional dilemmas and conflicts connected to the task of care.
