Teaching English language for specific purposes is still a field in which new venues and perspectives are unfolding. Innovations have been driven so far because of new knowledge and proliferations of integrated instructional models. The focus is no longer on grammar but using language as a means of connecting with others around the world. That is because the purpose of learning languages has changed towards intercultural communication. This field is more learnercentered, more collaborative and driven by technology which supplies English language in authenticity and literacy. Thus, in this paper we aim at showing the most effective ways of teaching English for Specific Purposes through textbooks which should contain job-related English lessons which can be effectively taught through the means of new technology and extracurricular supplementary activities. As ESP professionals, we must be ready to develop courses that teach authentic language from many different fields, based on accurate needs analysis and appropriate materials and methodologies.
