In the 21st century, cosmopolitanism has become an ever emerging concept, as scholars turn to this worldview with the hope to address the unavoidable impacts of globalization. Simultaneously, the new educational trends in Europe in combination with the ongoing socio-political changes create new needs that demand a more cosmopolitan interference. With this in mind, the present research attempts to examine whether and how cosmopolitan ideals are promoted through education policies in Europe and to what extent these cosmopolitan ideals succeed to reach national policies and school practice in a country as Greece. To this end, the author conducts a qualitative multilevel study between Europe and Greece and bases her study on two research methods: interviews and document analysis.     The interview and document analysis that follows leads to a comparison not only between the European and the Greek context but also between the policy and practice level that spawns a better and deeper understanding of how education promotes and can promote cosmopolitanism. The findings of the research highlight that the dilemma of whether to employ an ethnocentric or cosmopolitan educational approach can be acute. Parallel to that, the conflicting conceptions of cosmopolitanism between Greece and the European Union tend to render the moral aspects of education quite numb. Finally, the research closes with some recommendations for the future and suggestions for further studies.
