The Collaborative for Academic, Social, and Emotional Learning (CASEL) is a leading organization advancing the development of academic, social and emotional competence for all students. Their mission is to help make evidence-based social and emotional learning (SEL) an integral part of education from preschool through high school. SEL programming is based on the understanding that the best learning emerges in the context of supportive relationships. This resource will be paramount in developing strategies for socio/emotional support in curriculum and providing practical examples of how supportive relationships shape academic outcomes.
