Background of the project European and global society is influenced heavily nowadays by the impact of globalization, mobility, migration, cultural changes, development of various subcultures, fast-forward lifestyles, lack of coherence in the political policies, confusion and distress related to the security and stability of the future etc. The rise of extreme rights groups, discrimination and social exclusion, hate speech, racism, violence, etc. and lack of adequate support systems is growing in culturally challenged communities. Youth workers have to face all these issues and constructively address them with their beneficiaries and very often they lack adequate competencies in this sense. The "Differences Challenge Assumptions" training course wanted to address the lack of advanced intercultural working competencies and sensitivity in the youth work field especially of the ones active and working in international, diverse or multicultural settings. The main goal of this project was to increase the level of intercultural competence, sensitivity and quality in the youth work field. More specific Objectives that contributed to achieving the main aim: • To increase/upgrade the competencies of youth workers for understanding on a deeper level and navigating topics such as worldviews, identity, privilege, assumptions, norms, power relations, relativism, diversity clashes, intercultural sensitivity, etc.; • To contribute to a deep understanding of the global settings and influences on the diversity awareness of young people; • To develop highly sensitive attitudes in the youth work field towards diversity; • To empower youth workers to act as responsible intercultural sensitive actors in the international field and projects.
