Social and emotional learning (SEL) is a critical developmental process where children acquire and develop the skills, knowledge, and attitudes necessary to manage emotions, develop and maintain relationships, and make appropriate decisions. The purpose of this evaluation was to examine how the Emotional ABCs Program increased students' social-emotional competence. Emotional ABCs is an SEL program designed to help children in kindergarten through third grade develop age-appropriate SEL skills and abilities. The study included 473 students in first and second grade at eight different elementary schools, in 22 different classrooms across the United States. SEL scores were measured at two time points approximately eight months apart, before and after the timeframe in which students participated in the Emotional ABCs Program. All students' SEL scores increased between the two measurement time-points, and importantly, students who participated in the Emotional ABCs Program significantly increased their SEL scores by approximately five more points than students who did not participate.
