This glossary defines a selection of terms used in the field of vocational education and training (VET) policy in Europe. It is intended for researchers and practitioners and more generally, for all those involved in VET policy. It does not represent an exhaustive inventory of the terminology used by specialists; rather it identifies key terms that are essential for an understanding of current VET policy in Europe. This glossary, published in collaboration with the European Training Foundation (ETF) in Turin, has been prepared in collaboration with Cedefop's Translation Service, VET experts... and a number of the Centre's partners. It is in six languages, namely English, French, German, Czech, Hungarian and Polish. It is our hope that this work will aid communication among stakeholders and contribute to a better understanding of European Union VET policy.
