In Spain intercultural mediation developed within the framework of interculturality fostered by the European Union and stimulated by the arrival of foreign-origin populations. This has meant rethinking the policies and actions implemented to incorporate this new population. The schools, which reflect the social reality, have gradually responded to the needs that have been detected. Thus, within inclusiveness, interculturality and intercultural education, it was believed that the intercultural mediator was a figure (whether professional or natural) whose work could improve intercultural relations. From a survey of representatives of management teams (from 1,730 Spanish primary schools), the extent to which intercultural mediation are used and the functions attributed. The results indicate that intercultural mediation has not been consolidated, but competes with other professional profiles for its own field of intervention. Furthermore, although the mediators are positively valued, their action is mainly focused on conflict resolution.
