Interventions in emotional competences and scientific studies of emotional competence are flourishing in the educational context. However, we find very few programs in Europe involving emotional interventions in vocational education and training (VET) and a dearth of scientific contributions. Our purpose with this paper is twofold: (a) we provide the state of the art on existing international scientific publications about emotional training interventions in VET and a summary of existing programs at the European level; (b) by relying on the analysis of relevant cases in the educational literature, we provide guidelines about how scientifically-based interventions in emotional competences in VET could be developed. Ultimately, our goal is to open a discussion of emotional training as a novel domain of research for VET scholars and practitioners, and of how emotional competences could be introduced in a vocational curriculum.
