"This project was born from the gathering of five polyglot schools representative of the diversity of Europe, all of them with experience in conducting European projects and eager to collaborate on the same subject ""living together"". At a time, when Europe is confronted with problems involving its future, where a strong reference structure is needed in the face of global giants, it was important for us to bring together people of good will from same continent with similar but different cultures to address the issue of social inclusion and make it a horizontal priority.The main objective was to raise the awareness of young high school students about the difficulties of living together in all the partner institutions that are similar and complementary but have different backgrounds and audiences. The idea was that everyone can enrich the other through his own experience and the pooling of forces to reduce prejudice in school and to acquire sustainable values that he can transmit himself to build the world of tomorrow with a European citizen conscience based on tolerance, openness to others and favorable to employability.The idea of building a common charter laying the foundations for living together was imposed on everyone. To achieve this, each partner country has decided on the activities to be implemented leading to the identification of specific biases, and in particular that of gender, which has reached consensus. Each one was free of the various means to exploit to remedy it within the framework fixed previously. The meeting times during the learning activities made it possible to take stock of their accuracy, their relevance, to measure their progress and to project themselves.The results achieved are beyond our expectations considering the interest that young people have in this regard. The richness of their productions testifies as well as the progress made in languages, digital, speaking, relational, autonomy and state of mind. Such a journey has significantly changed their behavior, their approach to each other and their worldview.Young people who are involved in this project are now trained: their daily work shows their ability to reuse their knowledge, know-how and skills. They are capable of autonomy, of taking initiatives and even for certain responsibilities. In addition, their relationship to the teacher has changed from a wait-and-see posture to a benevolent horizontal posture. We can only welcome this progress and perhaps to have aroused future careers.For all young people and adults, this project has been punctuated by very beautiful meetings, some of which are in the process of becoming permanent. Moreover, he broke the elitist, confidential and time-consuming image that some could still have. Finally, our schools have gained visibility, recognition and influence in the minds of families, the public, municipal and local authorities. From now on we are solicited for projects with varied subjects allowing a wider opening to society and to the world."
