The DEEM project focuses on improving student well-being, inclusion, and emotional awareness in upper secondary schools. The partners collaborate to understand why some students struggle to attend school and to develop tools that promote happiness, emotional literacy, and inclusion in daily school life. The DEEM project empowers young people to recognize and manage emotions, builds inclusive school cultures, and strengthens the connection between emotional well-being and academic success. Teachers gain tools to support students more effectively, and schools benefit from sustainable practices that promote mental health and belonging.
