Cedefop’s recent research paper, Migrants, minorities, mismatch? Skill mismatch among migrants and ethnic minorities in Europe shows that migrants from outside the European Union - over half of the total migrant population of 6.8% of the employed population of the EU – typically find jobs beneath their real skills level (‘overeducation’), while ethnic minorities are more likely to lack the educational level required by jobs (“undereducation”). So what can policy-makers do to make better use of these workers' potential?
