Research Findings: The connections between parents' emotional competence (emotion expression, regulation, and knowledge) and children's social-emotional learning (SEL) have been well studied; however, the associations among teachers' emotional competencies and children's SEL remain widely understudied. In the present study, private preschool and Head Start teachers (N = 32) were observed using the Classroom Assessment Scoring System. Participating teachers from each center also participated in focus group discussions about emotional competence in preschool classrooms. For analyses, teachers were divided into Moderately and Highly Supportive groups based on observed emotional support quality. Teachers' focus group responses were compared. Practice or Policy: Comparison groups differed with regard to their discussions of emotion regulation and emotion knowledge. These differences elucidate ways in which intervention programs and in-service training can be developed to help teachers better meet the SEL needs of children.
