We aimed to investigate the relationship between ethnic prejudice and the perception of inclusion of immigrant children among primary and middle school teachers, focusing on the mediating role of resilience. Participants were 261 teachers, 233 women and 28 men, ages 34 to 66 (M = 51.67; SD = 8.27), recruited in primary and middle schools in Sicily (Italy). Participants completed the Classical and Modern Racial Prejudice Scale, the Resilience Process Questionnaire, and an ad hoc questionnaire for evaluating teachers’ perception of inclusion of immigrant children. The results showed an effect of ethnic prejudice on the perception of inclusion of immigrant children and on resilient reintegration. The mediation model showed that resilient reintegration partially mediated the relationship between ethnic prejudice and the perception of inclusion of immigrant children. Educational and practical implications are provided.
