The notion of care is the guiding principle of nurses’ initial training. What are the theoretical references on which these teachings on care and caring are based, in order to guide learning and its implementation during encounters with patients? Each professional practices his/her profession with a personal vision, but the history of the profession reflects the evolution of the society to which it belongs. Thus, care theories shed a new light on the framework of thinking related to caring and care today. In implementing the construction of training related to the new curriculum, the trainers at the ISFI (nurse training institute) in Pontoise wanted to question the concepts and theories on which the teaching of clinical reasoning can be based, and thus work on the links existing between their own experiences of caring and their missions of accompaniment and transmission based on the respect of the potential presented by the students.
