ENNowadays, ESP and CLIL are the two main players in the language teaching arena in global tertiary education. The aim of this paper is to evaluate the “strengths” and “weaknesses” of these two approaches and their methodologies. The data have been collected through interviews to trace: (a) factors that cause a university to adopt one language teaching methodology over the other; (b) advantages and disadvantages of each one; (c) level of teachers’ professional satisfaction in using CLIL or ESP, and (d) availability of didactic tools and materials. Keywords: English for specific purposes (ESP); content-language integrated learning (CLIL); multidisciplinary language learning; language awareness; teachers’ job satisfaction. [From the publication]
