Social movements are the main actor of the Social and Solidarity Economy (SSE). In order to understand the synergies and conflicts between the SSE and the public sphere, it is of particular interest to analyse the relations between popular movements and government institutions. This article investigates the degree of cogovernance, in social policies, between movements and governments of the so-called progressive wave in Latin America. The subject of study is the Bolivarian Alliance for the Peoples of Our America - Peoples' Trade Agreement (ALBA-TCP) and its social missions, as well as the Continental Articulation of Social Movements towards ALBA (ALBA Movimientos) and its political training schools. This work is based on Participatory Action Research, developed over more than 7 years, with stays in Argentina, Bolivia, Venezuela, Brazil and Chile. There have been used the techniques of participant observation and more than 40 in-depth interviews with government representatives and militants from social movements. The analysed dimensions focus on defining conversational partners, spaces, decision-making models, funding and the educational method in the possible practice of co-governance. Regarding the results, it is worth noting that, despite the efforts made and the progress achieved in deepening the relationship between social movements and public institutions in social policies, in none of the Latin American countries does cogovernance exist in strict terms.
