This qualitative study, conducted in the context of the postgraduate program “Education and Human Rights”, delves into the identities of school-age youth and their forms of social participation through the example of participation in school-based art groups. Focusing on three groups involving young people aged 15-18 in artistic and cultural activities (cinema and music), the research aims to investigate the social meanings involved in youth participation and whether it translates into social action. Utilizing the methodology of observation and focus groups with young people, the study highlights the importance of art and creativity as a means that provide young people with opportunities to express their perspectives on social issues and intervene for change at a social level, while expressing their claims. The findings highlight the importance of school-based art groups as social spaces, outline youth identities and explore available forms of youth participation. Finally, this research sheds light on young people’s participation in school-based art groups as a multifaceted issue that contributes to identity formation processes and cultivates a sense of belonging, the development of actions and the formation of claims. The implications of these experiences extend far beyond school, highlighting the vital role of the arts in shaping socially conscious and active citizens.
