Contextualizing the role of teachers in social‐emotional learning (SEL) in Malawi, we examine how teachers’
comfort
with,
commitment
to, and perceived school
culture
toward SEL relate to their actual teaching of it. Using surveys from 432 primary school teachers (20–60 years old), we found teacher
comfort
and supportive school
culture
were positively related to integration of SEL into classroom instruction, while
commitment
had no statistically significant relationship with implementation. We explore plausible explanations for these findings by interviewing 42 teachers. Together, our findings highlight the importance of teacher support systems and cultural compatibility of the curriculum for successful SEL implementation.
