Definition

An English-language learner (often capitalized as English-Language Learner or abbreviated to ELL) is a person who is learning the English language in addition to their native language. This can refer to any learners of English as a foreign or second language, but more often the term is used to refer to learners of English as a second language in mainstream schools where English is the language of instruction.

Key Terms

The terms used to describe ELLs blur, overlap, and change with time, as well as with shifting socio-political dynamics.

ELL (English Language Learner): an active learner of the English language who may benefit from various types of language support programs. This term is used mainly in the U.S. to describe K–12 students.

ESL (English as a Second Language): formerly used to designate ELL students; this term increasingly refers to a program of instruction designed to support the ELL. It is still used to refer to multilingual students in higher education.

LEP (Limited English Proficiency): employed by the U.S. Department of Education to refer to ELLs who lack sufficient mastery of English to meet state standards and excel in an English-language classroom. Increasingly, English Language Learner (ELL) is used to describe this population, because it highlights learning, rather than suggesting that non-native- English-speaking students are deficient.

EFL (English as a Foreign Language) students: non- native-English-speaking students who are learning English in a country where English is not the primary language.
