The aim of the paper is the analysis of the immigrants' school insertion paths in Italy. The analysis focuses on the immigrants' school participation in the secondary school, considering also the first and the second generation. The data has been extracted from official statistical databases, mainly of the Ministry of Education and Istat (Italian National Statistics Institute). The analysis points out that the participation rates of foreign students in the secondary school are lower than those of the Italian students and both of them are different among regions and provinces. Five territorial areas are distinguished through some social and economic indicators (sectoral added value and number of industrial districts) in order to show the determinants of different participation rates between foreign and Italian students. A multivariate analysis by territorial areas reveals that the main factors affecting the education choices are related to the local characteristics and the economic variables, such as total families' income and gross national product (GNP) per capita. These results suggest that the immigrant students face with many difficulties in educational attainment preferring a fast entrance in the labour market.
