The project team, composed of 4 associations (GONES Force 6 in France, Bolu Youth Association in Turkey, Dynamo International in Belgium, and ASD A.M.E.C.E. Baity APS in Italy, and Magdalena Ilieva) met in a Salto Youth training at the end of 2020. During this training, they were assigned to a smaller group, which had to present a Youth Exchange project : they named it PEACE (Place for Experimentation and Awareness through Cultural Exchanges), and decided to do it. So, they met lots of time on Visio to create the application form of what finally was named BOOST, Be On One Stage Together, beyond borders and cultures. These partners worked side by side and wrote all the different parts of the application form together. That is an uncommon way of creating an application form, as usually, partners join a project, but don't contribute to its completion. We benefited from the help of a coach too, who made us sharpen our aims, public target, actions to be implemented... As soon as we got the "GO" from Erasmus, we relaunched regular meetings to prepare at best the 2 forecasted activities : a pre-visit and the Exchange itself. From the beginning, the project team had identified 4 main common needs in their local realities. 1. The lack of opportunities for young migrants to meet and socialize with their native peers : formal education can prevent from that and let them prefer enjoying their free time in their living neighbourhood, so outside school they often don’t exchange with peers from different backgrounds. Some of the project partners already implement, projects aiming at creating a safe place and time in which young migrants and natives can get to know each other better, discover and discuss about interculturalism via a peer-to-peer approach. 2. The lack of cultural awareness and a rather general negative attitude towards diversity, which induces closedmindedness and prevents from interaction and acceptance of other cultures. The partners had experienced that both migrants and natives have difficulties to deal with the complexity of the cultural and social realities they face. 3. As far as young migrants are concerned; the partners had seen a set of “barriers to access”. Both newcomers and second/third generations (especially those coming from disadvantaged families living in France or in Belgium) who get difficulties in being more integrated because they face obstacles (linguistic, economic, administrative, social, or cultural) preventing them from a status of full membership in the society. Differences in the types of documents needed for legal residence, citizenship, national laws and the rights had been seen as another barrier. So, the project s wanted to unveil barriers and make them feel not so different from their peers. 4. Some common communication problems, both verbal communication (migrants are not speaking the language of the country they arrive in ; natives are not speaking the language of the migrants), and non-verbal communication including socially acceptable norms of behaviour (which can vary from one country, one culture, one religion to another). In their local work with these target groups, the project partners had noticed how powerful were the opportunities of dialogue and mutual understanding to foster the curiosity of the young people and raise new questions about oneself and the others, including the respect to the community and the broader society they live in. Long lasting friendships was a potential outcome too. The project team had identified other barriers that could affect young people with fewer opportunities : disabilities, education system, cultural, social or economic differences, discrimination. The identified needs were addressed, while involving 3 categories of young people with various backgrounds : 1. New migrants, including asylum seekers, refugee status ... 2. The “second” and “third generations”, the children of migrants who still face the consequences of their elder’s mobility. These youngsters are usually seen as a bridge between cultures and generations. But, French and Belgium partners had assessed that such a role was not so easy to perform, while it could empower to reflect and define ones' identity and contribution for a multicultural society. And young migrants struggle to feel included in the society they grew up in ; this sometimes induces a social immobility, that is paradoxical considering their elders’ desire for a better life for their family. 3. “Natives”, who didn't experience cross border migration in their personal or familiar biography and could be unaware of the barriers that migrant peers daily face. 7 objectives wanted to help the youngsters to feel as real European citizens : 1. To increase ones' sense of initiative 2. To impulse self-empowerment, self-esteem 3. To enhance interculturalism 4. To promote citizenship 5. To better known European values, projects 6. To be ready for other non/unformal trainings 7. To improve ones' IT skills
