This article describes processes of the inter-culturalisation of Flemish youth assistants towards the observation of strict orthodoxy among their Jewish community. By means of a situational analysis, a methodology based on Social Worlds Theory, the author investigates which problems Flemish social workers and the strict Jewish orthodox community interact and which positions they employ for this purpose. We investigate what makes these interactions (im)possible and offer insights in to the specific role of interculturalisation. Flemish social workers consider models on society and integration other than those of the strict Orthodox Jewish society. Thus both parties seem to apply different strategies to enable intercultural assistance. This article examines some of the consequences of this and suggests some improvements.
