Bilingual education refers to educational approaches that use two languages for classroom instruction. The goals of bilingual education include teaching English, fostering academic achievement, preserving cultural heritage, and enabling students to learn a second language. There are two main patterns of bilingual language development - simultaneous bilingualism, where a child learns two languages at once, and sequential bilingualism, where a child learns a second language after establishing proficiency in their first language. Common types of bilingual education programs in the US include transitional bilingual education, where some academic classes are initially taught in a student's native language to support English acquisition.
