Drawing on panel data and multivariate regression analysis, this chapter explores possible change between two surveys: one conducted in 2002 and the other in 2005. The analysis is based on an index of trust that measures Palermo students' trust in persons who are not personally known to them. The chapter focuses on variables at the school level and the classroom level, for example openness of school structures, fairness of institutions, caring school environment, peer interaction, openness of classroom climate, and aspects of the school programme. Is it possible to see whether any of these institutional school variables have an impact on students' generalised trust? Is it possible to change students' values through civic education at a grass-roots level? The importance of institutions for the development of generalised trust has been analysed in several studies on social capital.
