Palliative care is active care delivered by a multidisciplinary team, in a global approach to the person suffering from a serious, progressive illness, in an advanced phase, with a fatal outcome. Their goal is to relieve physical pain and other symptoms, but also to take into account psychological, social and spiritual suffering.

Palliative care and support are interdisciplinary. They are aimed at the patient as an individual, their family and loved ones, at home or in an institution. Training and support for caregivers and volunteers are part of this approach.

Recent years have seen the development of teaching in the discipline both during the initial course and through continuing training actions, the latter based on the very notion of multi-professionality. But it is clear that during the initial course of health professionals, learning remains confined to professions, in silos.

It is in view of this observation that the 2015-2018 palliative care development plan in France proposed the establishment of transversal teaching, for health students, through its measures 4.1 and 4.2, lessons put in place at through local initiatives which are still underdeveloped.

It is therefore appropriate to question the methods of learning "know how to work together". This work therefore aims to reflect, through what can promote but also hinder interdisciplinary work, on the way in which health students can be taught to work in interdisciplinarity and in particular during their internships in palliative care structures
