Abstract :
[en] Research Findings: Research indicates that early childcare is beneficial forchildren’s language skills. Children from minority home language groupsespecially benefit from an early start. In this study, we investigated theassociation between early childcare attendance (ages 0 to 4 years) andlistening comprehension in the language of instruction in multilingualLuxembourg. In particular, we analyzed whether this association was mod-erated by home language. Multilevel regression analyses on large-scaleschool monitoring data revealed that results depended on the home lan-guage group. Early childcare attendance, especially for a duration of 3 years,was positively associated with listening comprehension in the language ofinstruction among children who did not speak that language at home.Children who already spoke the language of instruction at home, monolin-gually or multilingually, did not benefit from childcare attendance or dura-tion to the same extent. Practice or Policy: Our results extend the previousevidence on the potential of childcare to reduce disparities in the languageof instruction, which is key for academic progress and success. These findingsmay guide stakeholders in monitoring and enhancing the quality of thelanguage environment in early childcare settings, which could provide betterstarting points for children in linguistically diverse school populations.
