The study of integration processes, specifically focusing on the educational field, has reached a crucial stage with the emergence of the second generation. This paper focuses on the relation between a specific group of foreign adolescents, the so-called 1.5 generation, and schools. On the one hand, interviews and group discussions with students highlight how they build their socio-integration paths and, on the other hand, focus groups with teachers stress how schools try (or don’t try) to re-define themselves towards a more complex and heterogeneous school population.
