In the framework of the Europe 2020 Strategy, the European Union is actively committed to the recognition of social innovation. Through one of the seven flagship initiatives of this Strategy, “Innovation Union”, it aims to promote the development of social innovation. The European Union’s support for social innovation is more concretely highlighted in the European Social Fund’s National Operational Programme (NOP) 2014-2020: the development of social innovation projects that create jobs and social cohesion has been identified as one of the six major challenges to be tackled and axis 3 of the PON “Fighting Poverty and Promoting Inclusion” includes an opportunity for concrete support for social innovation. Within the framework of this SOP, the European Social Fund aims in particular to “support the engineering of projects for the development of social innovation”. The proposed operation is part of this framework. **The aim of the project as a whole is to develop social innovation in France as a key lever** **to develop activity creation, employment, social cohesion, combat unemployment and exclusion.** Accelerate the development of social innovation requires first of all the implementation of measures enabling its ownership by all the actors who can contribute to its support and support. The aim here is to achieve a genuine recognition of social innovation as a factor of solidarity and competitiveness and job creation. The work undertaken by the Advisory in 2011 with the support of the European Social Fund to design and start disseminating adapted tools on social innovation is now to be continued. But this is a first step to take. In order to develop employment in the territories concretely through the implementation of socially innovative projects, it is necessary to work in parallel with two other complementary and essential aspects: \- It is necessary, on the one hand, to deploy methods and tools to promote the change of scale of innovations, including their duplication from one territory to another. \- On the other hand, it is about capitalising methods, tools and good practices to assess the social impact of these innovations, in order to be able to convince them of their usefulness and to contribute to their development. The project consists of three main operational objectives each covered by an action fiche: 1. Accelerating the development of social innovation 2. Supporting the change of scale and duplication of social innovations 3. Develop social impact assessment
