SEL instruction is critical in schools because communities and educational leaders are starting to understand the interconnected nature of social-emotional learning and academic skills such as goal setting, managing emotions, maintaining positive relationships, showing empathy, and making responsible decisions (Data Quality Campaign, 2018). The problem is school leaders do not have enough knowledge and skills to be the lead learner in supporting social emotional instruction and student social-emotional learning in their schools. This lack of knowledge concerning how to support social emotional learning becomes an issue in the school environment. Therefore, the problem the team investigated is the perception of building principals of the strategies they implement to support Social Emotional Learning, SEL training experience, and the support they need as building leaders to effectively lead SEL at the building level.
