This paper aims at clarifying the relationship between being involved in different forms of participation and tolerance toward migrants in young people. Almost 3000 participants from two European-funded research projects - FP7 PIDOP and H2020 CATCH-EyoU - answered a questionnaire that measured socio-demographics variables, the dimension of fairness in school climate, different forms of civic and political participation, and tolerance toward mi-grants and refugees. The results are consistent between the two studies, showing that civic participation demonstrated a major positive effect on tolerance. Being older, female, born in a foreign country, having more educated parents, and perceiving fairness at school, were also conditions, which sustained the development of tolerance.
