In this article, Naouel Zoghlami draws on needs analysis as a fundamental approach to inform the design of a professional English curriculum at the Cnam, a unique French research institution of higher education dedicated to lifelong learning. While needs analysis is still not widely used in the development of English for specific purposes programs in French higher education contexts, this study attempts to fill this gap by revealing the kinds of tasks adult professional learners studying at the Cnam say they need to perform in English at work. One of the strengths of this study thus lies in relying on data provided by domain insiders rather than assumptions held by the researcher-teacher about what adults need to learn to inform a professional English curriculum. Study data provide the information needed to improve the existing syllabus and the basis on which to build relevant pedagogical tasks.
