ESP emerged in the 1960s as a prominent area of EFL teaching. It is an approach to teaching English that focuses on the specific needs of learners in their fields of study or occupations. ESP courses are designed based on a needs analysis to identify the language skills and topics required. They use authentic materials and aim to develop self-directed learning. The teacher's role is to organize the course, set goals and objectives, prepare appropriate materials, and evaluate students. ESP differs from general English courses in its focus on the specific language needs of professional learners.
