The COVID-19 pandemic has caused schools to close in an effort to prevent the further spread of the disease. This has impacted teachers and students around the world. This mixed-methods research study examines if social and emotional learning has a statistically significant relationship between teachers' participation in SEL training and teachers' self-reporting regarding their social and emotional competencies; the relationship between teachers' experience and teachers' self-reporting regarding their social and emotional competencies; and teachers' perceptions of students' social and emotional wellbeing following the global pandemic.
