Emotional intelligence is good for business. That is the growing consensus across sectors in recent years. In schools, the focus on people's well-being and interpersonal skills is called social and emotional learning (SEL). The Collaborative for Academic, Social, and Emotional Learning (CASEL) defines SEL as 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. With a view of SEL as foundational and essential for positive school outcomes, the Office of Educational Leadership and Learning at Florida Atlantic University, in collaboration with Dana Zorovich-Godek, adjunct instructor and policy leader at CASEL, recently launched a course of professional learning designed for school-based and district-level administrators to enhance their social and emotional competence and build their capacity for facilitating teacher and student SEL. This article presents an account of the professional learning program describing the general purpose and format, course content and the underlying research, and a description of the powerful impact of the program on participants.
