This report provides an overview and description of social and emotional learning (SEL) and service-learning (S-L) as tools to improve the lives and academic performance of students. It describes how the two practices are interrelated, and cites research evidence that supports the expanded use of both practices in the classroom. Also provided are descriptions of the essential elements required of successful SEL and S-L programs, examples of current successful programs, and a discussion of state activities and experiences. Lastly, the brief discusses a series of likely challenges that education leaders implementing SEL and S-L programs could face. The brief offers recommendations and advice for addressing such challenges and provides lists of available resources where more information can be found. It represents the first step of a new partnership of the Collaborative for Academic, Social, and Emotional Learning (CASEL), the National Center for Learning and Citizenship (NCLC), and the Laboratory for Student Success (LSS). This partnership was formed to assist education leaders in integrating social and emotional learning and service-learning programs and policies into their states, districts and schools.
