The implementation of a new reference system of training in nursing care requires trainers to develop new educational skills. These help students to transfer their experience to new situations of care. The study is based on the experience of two training institutes in nursing care which participated in European exchange programs. In this presentation, we are interested in the one that participated in the Leonardo da Vinci program. The analysis shows that the confrontation with a new reference field, Europe, leads trainers to modify their position by developing reflexive analysis and by using interactive educational methods. Therefore, they move from the “teaching” to the “training” process. The reference to concepts enhances the status of trainers who then become aware of their skills. Upstream to the project, it is the IFSI leader’s responsibility to put in place the conditions which promote success. This project, integrated into that of the institution, then becomes a training-action.
