The Collaborative for Academic, Social, and Emotional Learning (CASEL) has spent over 2 decades researching the importance of social-emotional learning (SEL). The CASEL's (2020b) research revealed that the implementation of evidence-based SEL programs led to an 11% gain in student achievement, fewer behavior issues, reduced dropout rates, and decreases in the areas of mental health issues. Social-emotional learning helps students thrive in school and life by teaching our youth to manage emotions, solve problems, and get along with others. According to the Centers for Disease Control and Prevention (2021), millions of American children live with depression, anxiety, attention/hyperactivity disorders, behavioral disorders, or other mental health issues. Currently, school-aged children grappling with COVID-19-related trauma--including the loss of routine, reduced social contact, and the negative economic impact on themselves and their families--may benefit from a well-developed SEL curriculum and support system. This study was designed to describe evidence-based approaches for SEL, explore supports teachers received through realistic teacher education with a strong focus on teachers' social-emotional competence, disseminate findings of the effects of an evidence-based approach to teaching SEL, and inform future recommendations for implementing a comprehensive Wellness Program within the educational setting. Findings revealed social-emotional competencies are perceived to yield positive benefits to students and teachers. Data indicated the evidence-based dual approach to teaching SEL is a vital component of student engagement and academic success. Social-emotional learning skills were found to increase emotional intelligence in 5th graders, foster a positive school culture, establish healthy relationships, and improve student engagement.
