But outside these two institutions there exists a less well understood world of colleges, diplomas, certificates and professional examinations - the world of post-secondary vocational education and training. Many professional and technical jobs require no more than one or two years of career preparation beyond upper secondary level, and in some countries as much as one-quarter of the adult workforce have this type of qualification (see Figure 1). Nearly two-thirds of overall employment growth in the European Union (EU25) is forecast to be in the “technicians and associate professionals” category - the category most closely linked to this sector (CEDEFOP, 2012).
