What is the characteristic of learners of special English?

There are three groups of English learners beginners, intermediate learners, and learners of special English. Beginners need to learn the basic of English. Students who have reached an intermediate level benefit from learning general English skills. But what about students who want to learn specialist English for their work or professional life? Most students, who fit into this third group, have a clear idea about what they want to learn. A bank clerk, for example, wants to use this specialist vocabulary and technical terms of finance. But for teachers, deciding how to teach specialist English is not always so easy. For a start, the variety is enormous. Every field from air-line pilots to secretaries has its own vocabulary and technical terms. Teachers also need to have an up-to-date knowledge of that specialist language, and not many teachers are exposed to working environments outside the classroom. These issues have influenced the way specialist English is taught in schools. This type of course is usually known as English for Specific Purposes, or ESP and there are ESP courses for almost every area of professional and working life. In Britain, for example, there are courses which teach English for doctors, lawyers, reporters, travel agents and people working in the hotel industry. By far, the most popular ESP courses are for business English.
