The project Double Check - Training for Youth Workers aims to strengthen the capacity of youth workers across Europe to prevent and counter the growing challenge of disinformation through non-formal education. From the perspective of daily youth work, the objectives are firmly anchored in the realities of frontline practice: to provide youth workers with concrete, transferable methods that can be applied immediately in youth centres, outreach activities, municipal programmes, and school collaborations with young people aged 13-30. The project responds to an urgent need identified through consultations with practitioners: while high-level media literacy resources exist, youth workers often lack practical, age-appropriate tools that are feasible to run in low-resource environments and that help them handle polarising content safely and inclusively. The first objective is to equip youth workers with a coherent methodology for verification and dialogue that translates complex concepts like lateral reading, source triangulation, reverse-image checks, or inoculation strategies into simple session plans, micro-cards, and checklists ready for youth work settings. By turning disinformation into a teachable moment rather than a disruptive risk, youth workers will be empowered to transform everyday encounters with manipulated content into learning opportunities for young people. A second objective is to cultivate facilitation competences that allow youth workers to moderate difficult conversations across difference, reduce polarisation, and maintain curiosity in environments where misinformation often touches on identity and values. Through structured rehearsal in a safe training environment, practitioners will gain the confidence to lead respectful dialogue, use pre-bunking scenarios, and apply de-escalation techniques, all of which are essential for inclusive youth work. A third objective is to produce and validate a shared “Double Check Toolbox” of at least twelve non-formal methods that are low-cost, modular, and offline-capable, ensuring that they are viable in rural areas, small organisations, and volunteer-driven contexts. By co-authoring this toolbox, participants will create a practical resource that extends impact beyond the mobility itself, standardising approaches within their organisations and making them accessible to colleagues who did not attend the training. The fourth objective is to embed recognition and sustainability in youth work practice. Structured reflection, daily documentation, and the systematic use of Youthpass ensure that learning outcomes are visible, validated, and portable across roles. At the same time, each participating organisation commits to adopting toolbox methods in its regular calendars, training cycles, and volunteer induction processes, thereby ensuring that outcomes translate into routine practice. Finally, the project seeks to strengthen the professional identity and community of youth workers by building a transnational network of practitioners who share methods, exchange cases, and co-develop solutions. This aligns with the broader goals of Erasmus+ to promote quality, innovation, and recognition in youth work. By fostering this community, the project ensures that the competences gained are not only personal but also collective, feeding into a wider European conversation on democratic resilience and the role of youth work in addressing disinformation. The project’s objectives are to transform disinformation from a threat into a pedagogical opportunity, to equip youth workers with practical tools and facilitation skills, to standardise these tools within organisations, to recognise competences formally through Youthpass, and to build a durable community of practice. These goals directly serve the Erasmus+ KA153 action by raising the quality of youth work, strengthening its capacity for innovation, and ensuring a lasting impact on the everyday work of youth workers with young people.
