An ELT Glossary : Language Immersion Programmes / Bilingual Education
Children participating in a language immersion programme receive anything from 50-100% of their school education in a language which is not their L1. For example English speaking children attending a French-medium school in Canada. If both languages are used, the programme may also be referred to as bilingual education.
