According to the Center of Applied Linguistics:
 “Bilingual education is an umbrella term for many types of programs in which two languages are used for instruction.
Dual Language education is an effective approach to developing language proficiency and literacy in English and a partner language. Two-Way Immersion, one type of dual language education, integrates native English speakers and native speakers of another language for academic content instruction through both English and the partner language beginning in elementary schools. Bilingual and Dual Language programs promote bilingualism and biliteracy, grade-level academic achievement and cross-cultural competence in all students. Students maintain their native language while adding another language, and they develop pride in their own culture while developing an understanding of others.”
