“The many acronyms and abbreviations used in the field of English teaching and learning may be confusing. English is a language which has great reach and influence; it is taught all over the world under many different circumstances. In English-speaking countries, English language teaching has essentially evolved in two broad directions: instruction for people who intend to live in an English-speaking country and for those who do not. These divisions have grown firmer as the instructors of these two “industries” have used different terminology, followed distinct training qualifications, formed separate professional associations, and so on. Crucially, these two arms have very different funding structures, public in the former and private in the latter, and to some extent this influences the way schools are established and classes are held. Matters are further complicated by the fact that the United States and the United Kingdom, both major engines of the language, describe these categories in different terms: as many eloquent users of the language have observed, The following technical definitions may therefore have their currency contested.” Wikipedia
