The waves of migration that have occurred since the second half of the twentieth century have contributed to make the Belgian population more multicultural and lead it to interact in contexts with multiple cultures. This can result in various attitudes, ranging from identity tensions to the acceptance of differences that allow the assimilation of the different cultures received by the host culture. This work allows me to position myself and to discover "intercultural mediation in schools". It is focused on the dialogue with students within the school about cultural issues, and how to create a link between parents and the school.
