The studies focus on the very existence of this training pathway, its traditional rootedness in certain specialities at the secondary level of the education system and its recent expansion into higher education. These studies analyse the trajectories of individuals who have completed an apprenticeship-based training programme and demonstrate the clear advantage these young people enjoy in the labour market, at least for those leaving education at the secondary level. The studies are also concerned with the use that companies make of this training pathway (e.g. the extensive use of it in the construction and public works sector), which enables them to retain more of the young people trained in the sector.
