The project aims to develop a digital and interactive toolkit to foster the inclusion and active participation of young people in the association sector, and in particular that of International Solidarity at the European level. Aiming to provide organizations and professionals with concrete tools to promote participatory and inclusive practices, the project, through the toolkit, supports the development of young people's skills and opens spaces for their participation, both in projects and in the governance of organizations. The toolkit will have a positive impact on organizational practices and professional skills development, fostering greater involvement and inclusion of youth in the associative sector and international solidarity organizations.
