The anthology should be seen as a contribution to a tighter combination of youth research and educational research. The integration function of the dual system is particularly important for disadvantaged young people in both professional and social contexts. This integration function is subject to changes due to the demographic changes, the shortages of skilled workers and the changes within the training processes. How do these changes affect the personality development and life planning of young people? What is the transition from school to training like and which factors influence the quality of the professional training?These are the questions, which were discussed in a conference organised by the Federal Institute for Vocational Education and the German Youth Institute and which are addressed in the anthology on hand.
