The Collaborative for Academic, Social, and Emotional Learning (CASEL) is the nation’s leading organization advancing the development of academic, social, and emotional competence for all students. Its mission is to help make evidence-based social-emotional learning an integral part of education from preschool through high school. To that end, CASEL has identified five interrelated SEL core competencies: self- management, self-awareness, social awareness, relationship skills, and responsible decision-making.
