The social work profession operates in the context of the implementation of a partnership between school, family and community. In this context, the social worker is assigned the role of supporting parent participation in the school environment. This role is put into perspective regarding the practices relating to the participation and social action that are characteristic of the profession. The tensions that arise between the fields of Education and Social work lead us to define this role around a socio-cultural logic where the Social worker is considered a cultural mediator.
