English Language Learners (ELLs) who are learning English as an additional language must be able to do more than just talk to friends, buy things at a store, or find their way around the city. Students must understand different ideas and be able to read, write, and talk about the ideas. This is called Academic English.
The teaching of English as an additional language in an intentional, systematic way to ELLs is called English Language Development.
Students need academic English to finish senior high school. It is also important for college, university, or future employment.
