ABSTRACT Developing emotional competence during childhood is critical because it is a significant resource for building psychological well-being, social relationships and even school achievement. Language plays an important role in fostering emotional competence among monolingual children but for bilingual children, the relationship between culture, language and emotions is significantly more complex. Although bilinguals may have more emotion concepts due to their engagement in multiple languages and cultures, this potential may only materialise under specific conditions. In this study, we investigate whether ethnic minoritised bilingual children’s emotional competence (i) differs from that of majority monolingual children based on their language proficiency profile and (ii) is shaped by their exposure to the majority culture, independent of their language competencies. Using a sample of primary school children (aged 10–12; N = 924) living in Belgium, the results of our quantitative analyses suggest that being fluently bilingual is beneficial to fostering emotional competence for minoritized children. However, Belgian socialisation efforts, exposure to Dutch media and demographic proxies of the degree of cultural exposure were not significantly related to emotional competence. Our results contradict contemporary deficit views surrounding bilingualism and suggest important policy implications for educational professionals.
