Around the globe, dialogs about educational reform and the integration of social and emotional learning (SEL) into policy and curriculum are proliferating. SEL is now a worldwide phenomenon and not just a passing fad, with SEL approaches and programs being implemented in countries throughout the world. Articles included in this special issue are authored by several of the SEL pioneers whose papers represent the current and emerging innovations in the field central to advancing SEL research. I offer 3 observations raised collectively in these articles: (a) social and emotional competencies predict children's success in school and in life, (b) social and emotional competencies are malleable--they can be taught and assessed, and (c) explicit attention to context is foundational to the promotion of SEL. I also provide some additional suggestions for advancing SEL work, including (a) understanding and promoting teacher well-being, and (b) integrating SEL into teacher preparation.
