Peace education aims to educate people to become peace agents and help build peaceful communities. It teaches the values, knowledge, attitudes and skills needed to live in harmony with oneself and others. Peace education is transformative and addresses the cognitive, affective and active dimensions of learning. It cultivates understanding and challenges beliefs, perspectives and systems that have caused violence and conflict. The goal is to transform societies and create conditions for nonviolence, justice, human rights and environmental sustainability. Effective peace education adopts a holistic approach and engages the entire school community.
