The Wallace Foundation's Partnerships for Social and Emotional Learning Initiative is a six-year initiative that The Wallace Foundation launched in 2017 to explore whether and how children benefit when schools and their out-of-school-time programs partner to improve social and emotional learning (SEL), as well as what it takes to do this work. According to the Collaborative for Academic and Social and Emotional Learning, SEL is "the process through which children and adults understand and manage emotions, set and achieve positive goals, feel and show empathy for others, establish and maintain positive relationships, and make responsible decisions." This case study explores how Lister Elementary School in Tacoma, Washington, established SEL and equity as a nonnegotiable foundation for its work with students, staff, and families. Lister staff received comprehensive support in their SEL and equity work. This included written SEL lessons that incorporated racial equity, a range of training opportunities developed and led by Lister school administrators, regular check-ins and opportunities for input during standing staff meetings, and feedback provided through formal and informal evaluations. Lister established schoolwide consistency with regards to SEL. Students and staff used common terminology to communicate about SEL. The SEL scope and sequence was designed to ensure that the same concepts were reinforced across classrooms and evolved as students progressed through each grade.
