Worldwide there are collaborations between NGOs that are committed to the acceptance and implementation of the UN-Convention on the Rights of the Child. The main task of these so called `National Coalitions (NC) is the reporting process to the UN-Committee on the Rights of the Child. The Committee reviews the progress and the obstacles of the realization of Children`s Rights of every member state on a regular basis. NCs emerged as a result of article 45b of the Convention on the Rights of the Child that allows independent expert submissions to the Committee on the Rights of the Child. Often the National Coalitions play a substantial role in the mobilisation of the civil society for children´s rights issues and act as a voice for children in their countries. One important challenge is to involve children at a meaningful level, but only a few of the coalitions have mechanisms in place that ensure the active participation of children in their work.The NCs of Austria, Germany and Switzerland want to build a strategic Partnership (from September 2016 until February 2018) to exchange best-practices in children´s participation. This partnership will strengthen the transnational cooperation and build capacities for transnational projects. In the course of 3 transnational meetings we will exchange ideas, methods and best practices regarding children and youth participation. The two main questions that will be the focus of our discussions are:>> How can participation of young people succeed in the monitoring process of the CRC?>> How can long-term participation of young people succeed in an institutional context of the work of NC?Besides the thematic discussion this partnership is meant to build capacities for future transnational cooperation. Throughout the project period 3 transnational meetings will be organised. Representatives and member organisations, who deal with the topic of child participation of every NC of the partner countries, will take part.Relevant stakeholders of politics and administration will be involved in the project strategically. In the course of the 2nd transnational meeting, which will take place in Geneva in June 2017, actual children participation is on the agenda. Six adolescents aged between 16-18 years, coming from different backgrounds and therefore representing various groups of young people, will be involved in the project. They join the project meeting in Geneva and gain experience locally with the UN Children's Rights Committee. Their impressions and opinions will be an important feedback for the discussion of the question, which factors contribute to a successful youth participation in the UN child rights monitoring process.In the last three months, the collected results will be summarized in five outcome documents (partly translated into English) and published.Resulting documents: (1) Experience in youth participation in NC context, (2) Best Practices of youth participation at the UN Children's Rights Committee, (3) National Recommendation catalogues for implementing long-term youth participation in NCs, (4) Conclusions concerning further transnational cooperation (5) Process documentation and evaluation / process support. The fifth document includes conclusions and recommendations of an external evaluation process that should accompany the project from start to finish.Starting in 2018, all results will be disseminated on both national as well as at international level. This will be an important step for initiating youth participation at institutional level of the NCs involved in the project. In addition to the 21 people who make up the national "core team" (15 professionals in the field of children's rights work and 6 young people), another 300 people will be involved through discussions and networking activities in the project.The strategic partnership "Best Practice of child and youth participation in the children's rights networks in Austria, Germany and Switzerland" can thus on the one hand build the foundation for sustainable, transnational cooperation and on the other hand influence the development of youth participation within the participating organizations and the United Nations.
