How is ESP different from English as a Second Language, or general English?

The major difference between ESP and ESL lies in the learners and their purposes for learning English. ESP students are adults who already have familiarity with English and are learning the language in order to communicate a set of professional skills and to perform particular job-related functions. An ESP program is therefore built on an assessment of purposes and needs and the functions for which English is required.

As a matter of fact, ESP is part of a shift from traditional concentration on teaching grammar and language structures to an emphasis on language in context. ESP covers subjects ranging from accounting or computer science to tourism and business management.

For students specializing in the English language and literature the field of professional activity covers all kinds of transnational communication ranging from teaching ESL to interpreting or translation in international tourism and business servicing. The ESP focus means that English is not taught as a subject divorced from the students' future jobs; instead, it is integrated into a subject matter area important to the learners.
