The main benefits of English for Specific Purposes (ESP) courses are:1. Faster acquisition of required linguistic items due to focus on teaching language for specific purposes and authentic contexts.2. More efficient use of learners' resources through accelerated and intensive learning.3. Greater effectiveness in using language appropriately and correctly in job-related tasks after completion of the course, as needs are identified prior to learning.4. Contrast with General English courses, which lack relevance to learners' specific needs and deal with many different topics at a superficial level.5. Needs analysis is an essential component of ESP, helping identify learners' skills and knowledge requirements for their chosen profession or occupation.
