This research aims at highlighting the specificities of the entrepreneurship support program proposed by a French “activity and employment cooperative” we are currently working with. Competence development focus is used in this perspective. We are able to find out two levels of singularity : i) the mix of action-training and part-time work-based learning, and ii) the amplifying effect in the collective and cooperative support framework. Then, the discussion that follows confirms the fruitfulness of such a program. The conclusion insists on the value of these exploratory results while generating prospects for future longitudinal research.
