The research started from the problem of discrepancy between the discontinuity of the public policies programs of design in the state of Rio de Janeiro and the solid professional performance of fluminense designers. In this way, the hypothesis defended is related to the strengthening of the public policy to promote design, through the support and articulation between actions of the fluminense designers in their processes of professional and political activities. Consequently, we argue that the professional activity of designers is relevant in the definition and execution of these policies. To corroborate such hypothesis, the general objective of the study was the proposition of a model of a public policy to promote design, in which the designers plays a central role. Therefore, in order to understand this role, the object of study was the participation of designers from the state of Rio de Janeiro in state design policies. The actions of the Program Rio é Design, from the State Government of Rio de Janeiro, were analyzed, seeking to understand the performance of the designers promoting the design activity as exhibitors of the Rio(more)Design exhibitions and participants in the Design Business Rounds. Moreover, public policy models were identified to relate them to the actions of designers professionals as promoters of local state design. The original contribution of this research is the proposal of an innovative public policy model of design promotion based on the participation of design professionals as main actors.
