The training center "LabBriq Sociale" is a social fablab, open at Montreuil in Seine Saint Denis (a popular district near of Paris). Here, the social context is difficult, the unemployment rate is high, so lot of young people have nothing to do, risking to fall in delinquency. There are social criterias for the selection of profiles. The curriculum is free and open for students, aged between sixteen - twenty five years old, and who have dropped out to school and/or non-degree . They follow a training on digital fabrication for learn skills and individual's self-identification in social group. This structure can't delivering any diplomas, but it's a device for re-engagement and a work on identity code. We have received the french label "Grande Ecole du Numérique" (Great Digital School) who certify the training device by the Ministry of National Education, and in addition to grants granted on social grounds.
