The paper emphasises the need to develop new global competence in the context of the demands of modern societies. Contemporary and future demands for highly skilled workforce in the global economy constitute a challenge for teachers and teacher-training community. New skills and competences are needed for the success of professionals and these skills should be a part and parcel of their vocational education. Development of global competence is emphasised in the context of the current approach of Global Development Education (GDE). The paper describes the current state of implementation of the GDE in Slovakia and briefly describes an example of GDE implementation in VET teachers’ preparation at the Faculty of Economics and Management of Slovak University of Agriculture. Several possibilities of implementation of global education into teachers preparation are described. Particularly, the conditions of a supplementary pedagogical course at the Slovak University of Agriculture were analysed. The analysis of the course curriculum revealed several higher education subjects which include issues of global education or have a potential to develop such themes. Also, the paper briefly describes the results of a small survey on secondary school pupils’ knowledge and opinions in some selected fields of GDE and a survey on secondary school teachers´ experiences with GDE. The aim of the paper is to highlight the importance of global development education (GDE) in the educational process at secondary vocational schools. The main purpose of global development education is to form att itudes necessary in new social conditions.
