What are the four major bilingual programs

The four major bilingual programs are:

1. Dual Language Immersion: In this program, students receive instruction in two languages (usually English and another language) for a significant portion of their coursework.

2. Two-Way Bilingual Education: Also known as Dual Language Education, this program is designed for students who are native speakers of both English and another language. Instruction is provided in both languages, with the goal of developing bilingualism and biliteracy.

3. Transitional Bilingual Education: This program is intended for students who are not proficient in English. It provides instruction in both English and the student's native language, with the goal of transitioning them into English-only classes.

4. Developmental Bilingual Education: This program is similar to transitional bilingual education, but with a longer duration of native language instruction. The goal is to promote academic achievement in both the student's native language and English.
