This article puts into perspective the convergence and interaction, through an institutional partnership, between the interest of public authorities and the interest of social actors in evaluation. It attempts to distill the significance of this phenomenon by looking at it as a form by which the movement of community groups is institutionalized as a co-producer and co-evaluator of public goods, while the welfare state assumes the role of a partner state. Lastly, it claims that we are witnessing a displacement of the stakes, and a redefinition of the field, of evaluation.
