Access to lifelong learning as a principle of equal opportunity, in accordance with the 1st key principle of the European Pillar of Social Rights, as recalled by the Council of the European Union in its recommendations of 22 May 2018, is the basis of our ambition to enable all detained persons to acquire the knowledge and skills needed to reintegrate a position in their own society once released.Providing a common thread to all educational actions, social integration is therefore seen as the very reason of the presence of our French teaching structures intervening in a prison environment.Despite an educational context which is heavily impacted by damaging discontinuities in life courses and due to multiple factors (among others, high turnover rate of people, large heterogeneity of learners, numerous constraints inherent to the operations inside a prison) the same requirements and the same references as those used in a free environment remain all the more essential to provide the learners with a central role, aiming at offering equal opportunities and ensuring the relevance as well as the quality of the training offer.This is why teachers inside prisons, even more than in an open environment, are expected to contribute to a constant restructuring of the proposed training offers by ceaselessly updating their own training and their teaching practices.The present project of establishing a time of reflection and a collective, firmly European work in a partnership context will allow to provide educational responses that are expected to minimize the negative impact of the discontinuity of the learning course on detainees.The European partners that are resolutely included in the process of this ambitious project are:- The Teaching Unit of the Auergne-Rhône-Alpes Region (France)- The Department of Education of the Penitentiary Center of Gherla (Romania)- The Nelson Mandela Adult Public Education Institution (EPAPU) of the A Lama Prison (Spain).- The CPIP, non-governmental organization, aiming at cooperation and innovation in the field of penitentiary action (Romania)What is expected through this two-year collaborative work is a collective attempt during six transnational meetings aiming at:- strengthening our respective and mutual knowledge of the existing penitentiary systems in the different countries,- identifying their implementation arrangements in educational purposes,- opening to our partners the doors of our classes, observing and co-animating teaching times,- facilitating the exchange of true experiences, and drawing up an inventory of the efficient teaching practices,- having a comparative look on the methods of dealing with learners in the partner countries in order to collectively build concrete recommendations regarding our professional, tutorial, teaching and organizational practices, with the aim of helping to provide a beneficial learning path for detained persons, along with a view to their social integration.What is expected to come out of this work will be materialized through the writing, experimentation, dissemination and exploitation of two tools:- a catalog of good practice compiling sessions and educational sequences that can be immediately reused in the teaching process used in detention,- an educational kit for the attainment of training schemes in a prison indicating the various stages of individualized training of detainees by teachers and educational teams, thus issuing recommendations in order to best position the student as a protagonist in charge for his/her own curriculum.We remain convinced that the mutual enrichment of daily practice in the classroom, the dissemination, sharing and sustainability of the innovative results of this project will hopefully be the decisive impact in terms of optimized management of the detainees' continuous training, a key element in one's reintegration.Our common working program will become by all means the basis of many even larger educational and organizational expectations. It will then constitute the crucible of their future collective pursuit, for the benefit of detained persons, via a subsequent and ambitious innovative project that will hopefully become enlarged to other partners, in the framework provided by our European Union.
