Influences of bilingual input on English vocabulary size and academic outcomes: a large-scale longitudinal study following children in Australia from five to ten years

Research from large population-based studies investigating the language and academic outcomes for bilingual children is rare. The current study aimed to investigate the influence of dual language exposure on (i) English vocabulary outcomes at 5 years (126 bilinguals, 1675 monolinguals), and 10 years (vocabulary: 92 bilinguals, 1413 monolinguals:), and (ii) academic outcomes at 10 years (107 bilinguals, 1746 monolinguals).
