Arizona Revised Statutes Title 15. Education § 15-751. Definitions

1. “Bilingual education/native language instruction” means a language acquisition process for students in which much or all instruction, textbooks, or teaching materials are in the child's native language other than English.

2. “English language classroom” means a classroom in which English is the language of instruction used by the teaching personnel, and in which such teaching personnel possess a good knowledge of the English language. English language classrooms encompass both English language mainstream classrooms and sheltered English immersion classrooms  1

3. “English language mainstream classroom” means a classroom in which the students either are native English language speakers or already have acquired reasonable fluency in English.

4. “English learner” or “limited English proficient student” means a child who does not speak English or whose native language is not English, and who is not currently able to perform ordinary classroom work in English.

5. “Sheltered English immersion” or “structured English immersion” means an English language acquisition process for young children in which nearly all classroom instruction is in English but with the curriculum and presentation designed for children who are learning the language. Books and instructional materials are in English and all reading, writing, and subject matter are taught in English. Although teachers may use a minimal amount of the child's native language when necessary, no subject matter shall be taught in any language other than English, and children in this program learn to read and write solely in English. This educational methodology represents the standard definition of “sheltered English” or “structured English” found in educational literature.
