Children with social and emotional skills do better in school, have improved relationships with peers and adults, are better adjusted emotionally, and have improved mental health. In contexts of violence and conflict where children and youth are disproportionately and uniquely affected, their resilience and social emotional well-being are essential to any post-conflict long-term reconstruction, development process or long-standing peace. Social and emotional learning competencies often serve as the core competencies outlined in most programs intended to build social cohesion before, during and after crisis and conflict. Although each program model might vary slightly, many of the most effective evidence-based programs such as conflict resolution, life skills, character education, violence prevention, civic education or peace education are designed to empower children and youth to have improved academic, social and emotional learning outcomes. In contexts of adversity, education systems are well advised to integrate social and emotional learning (SEL) components and processes into their academic programs.
