Populations not autonomous in their administrative relations has difficulties with access to social benefits of the Caisses d'Allocations Familiales (CAFs). These difficulties, whether rooted in cultural, educational, social, or other issues, disrupt the management of their documents of social benefits and thereby weigh on their economic situations. From 1998 to 2000, five CAFs tested suitable solutions to situations of beneficiaries for whom standardized procedures have shown their limits, in the areas of housing, compensatory allocations of revenues, and given territories. They have defined goals, methods, and indicators for complex situations and have regular assessments of the management of the project as the project is going on. These results concern a better understanding of the beneficiaries, understanding of the services to provide them with, and the benefits for the beneficiaries, for the agents, for the CAF, and for its relations with the partners associated with their missions.
