Recent statistics of IVS (International Voluntary Service) networks such as Alliance and CCIVS illustrates that international projects for teenagers, such as exchanges, meetings and workcamps, are succesful and show a high rate of participation. However, the number of international activities for teenagers is still limited compared to international projects for young adults.One reason for this trend is related to the specificities associated with teenagers, regarding group dynamic, responsabilities and legislation. These specificities are sometimes considered as constraints which prevent the development of projects for teens. Still, there is a huge demand for this kind of project which are getting popular every year as teenagers want to be actively engaged and spend their vacations with purpose.Through numerous years, Solidarités Jeunesse has organized many youth exchanges for teenagers (15 to 17 years) with a high interest in sharing its experience with other organizations. We are certainly convinced that these experiences could create a trigger for the youth to feel more included in the process of emancipation and be a source of liberation and raising awareness. Therefore, in cooperation with our international partners we propose this project that will first of all train youth leaders to be able to work with teenagers in non-formal context and as a result, will contribute to the development of numerous teenager projects. In addition, we would like to create with our partners a common work ethic with the teenagers to move towards the same goal of strengthening the responsibility, empowerment and the intercultural spirit of the youth.Objectives of the seminar:- to reinforce the capacity of partner organisations to organise international projects for teenagers;- to provide youth workers with quality online and offline tools to lead international activities for teenagers;- to increase the number of international projects for teenagers and make them sustainable;- to valorise the impact of international projects for teenagers;- to create a network of youth organisations organising teenager projects.In order to reach the objectives of the project, it was decided to organise a Steering Committee meeting and a seminar on quality youth work and inclusion models for teenagers, a training on organising and leading international activities for teenagers followed by experimentations with teenagers in participating countries. These experimentations will be facilitated by two international youth workers in terms of job shadowing supported by the hosting organisation and a local youth worker. The results of the project and a toolkit on international teen activities produced by partners will be presented during the Final Evaluation.In order to reach the objectives in a more effective way, it was decided to invite 3 experts on teen intercultural pedagogy and impact measurement, intercultural learning and pedagogy of teenagers and impact assessment
