This study investigated the conceptualization of children's socioemotional competence among parents and teachers of preschool children in Hong Kong, China. Focus groups were conducted with 16 parents and 18 teachers from three preschools. Thematic content analysis revealed that, reflecting the cultural as well as contextual characteristics of Hong Kong, parents and teachers expected socioemotionally competent children to master skills in emotion understanding, emotion expressivity, emotion regulation, relationship building, conflict management, and inhibitory control and cognitive flexibility. There was diversity within parents' and teachers' interpretations of the characteristics of emotionally regulated and socially skilled children. Findings highlighted the ecosystemic nature of societal ideas about children's developmental competence, demonstrated the utility of qualitative research in exploring these ideas in culturally sensitive manners, and called for the mobilization of parents and teachers as research-informed scaffolders of holistic development of children.
