This chapter focuses on the implementation of Youth Guarantee (YG) in Flanders and Brussels. Because of the Belgian federal government structure, the Belgian Youth Guarantee implementation plan consists of four different implementation plans: one for each language community and one for the bilingual Brussels-Capital Region. As both regions experience not only different socio-economic conditions, but also a different institutional framework in the approach towards youth unemployment, they provide together an interesting case to describe two different but interwoven contexts and implementations of the YG within one country. In Flanders, the YG was largely a continuation of previous policy on youth unemployment, whereas in Brussels, the YG Action Plan and the European funds were used to develop a whole new approach to young job seekers.
