This study investigates the impact of Filipina domestic workers (FilDWs), a marginalized group in Hong Kong (HK), on HK children's language development. It focusses on FilDWs' influence on the second language (L2) English of bilingual HK primary school children attending an English Medium of Instruction school. The elements investigated are L2 English spoken complexity, accuracy, and fluency (CAF), and reading accuracy and fluency. Participants comprise 34 children (17 boys and 17 girls, mean age 8;11) from homes with FilDWs and 30 (15 boys and 15 girls, mean age 8;11) from homes with no FilDW. Participants completed an English reading and speaking task, and an English working memory capacity (WMC) test. Participants from households with FilDWs scored significantly higher on all aspects of both English language measures, while no significant differences for WMC were observed. These suggest that FilDWs exert a positive impact on children's L2 English proficiency, placing them in a different position to the low status they are usually ascribed. These findings have implications for decolonizing and decentring language learning and teaching. Copyright ©2023 Oxford University Press.
