During the last 20 years, the influx of immigrant pupils in Spanish schools has taken up much of school counsellors' agendas. This leads us to reflect upon the status and role of educational guidance in terms of cultural diversity management, particularly focusing on two elements that may potentially help understand the situation: relations with other educational agents and the intervention model applied. The field work for this study was carried out during an academic semester in four secondary schools in Huelva. In addition to the analysis of official school documentation, remarks and field notes, semi-structured interviews were carried out and a discussion group was held with the four counsellors. Counsellors are trying to overcome an intervention model that is mainly therapeutic in nature and make space in their schedules for a way of working that is more focused on prevention and advisory services, incorporating the participation of other educational actors. But this is not an easy task. The possibility of generating changes would encourage better integration of cultural diversity in the life of schools, rather than treating it as a negative/deficit view, as an occasional issue, individual and isolated from the sum of school activities and other members of the education community.
