This chapter discusses different mechanisms that have conveyed the transfer of VET policies within the European Union in the last decades. A brief theoretical framework introduces the concepts of agency, structure, ideas and social relations, and spells out how these components of social action have woven certain patterns of policy transfer. Then, several sections about the EU education policy and the transfer of apprenticeships as well as of career guidance and skills validation analyse an interesting contrast between the driving mechanisms. While apprenticeships seem to circulate between European countries by means of policy learning, career guidance and validation seem to spread by means of emulation. This conclusion of the previous literature suggests several avenues for further research.
