Vocational Education and Training (VET) programmes have included the acquisition of transversal competences in their curricula as a tool to increase employability. The number of researches has exponentially grown in the last years, emphasizing its relevance and the multiple approaches and factors involved in the learning process. The present bibliometric study aims to provide an overview of the scientific research carried out during the last 10 years and to shed some light on several relevant topics in this field. The results indicate the need to improve students' transversal competences in order to meet the demands of the labour market, the importance of the collaboration of all the actors involved in the process (policy makers, industry and educators) and from a pedagogical point of view, the necessity of introducing new teaching approaches to implement and assess the acquisition of transversal competences. However, and despite the surge of interest in the study of transversal competences in the last decade, further empirical research is needed, especially at Vocational Education and Training level, to understand how transversal competences develop and what kind of initiatives have an impact of their acquisition.
