The implementation of the new reference system of training in nursing care requires from trainers to develop new educational skills. These allow to help students to transfer their experience in new situations of care. The study is based on the experience of two training institutes in nursing care which participated in programmes of European exchanges. In this presentation, we shall be interested in the one that participated in the Leonardo daVinci programme. The analysis shows that the confrontation with a new reference field, Europe, leads the 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 falls under IFSI head's responsibility to implement the conditions favourable to its success. This project integrated into that of the institution then becomes a training-action.
