Samenvatting

This study aimed to track language development and possible factors of language loss in 50 primary-school-aged bilingual Dutch-English children, and it follows up a study conducted one year prior. Dutch language skills were assessed through the standardized language test CELF4-NL and language background factors were assessed through the Alberta Language Environment Questionnaire. Reading books in the native language Dutch contributed significantly to children's language development. Speaking the native language at home with both parents and siblings contributed to better Dutch language skills. Additionally, schooling outside of the home situation in the native language seems to contribute to positive language development in children after one-year follow up.
