English for Specific Purposes (ESP) programs, characterized by the special needs of the language learners, are described and a review of the literature on a functional-notional approach to the syllabus design of ESP programs is presented. It is suggested that effective ESP programs should teach the language skills necessary to function and perform satisfactorily in a given function. The theoretical basis for an effective ESP curriculum can be found in a functional-notional syllabus design, which emphasizes the communicative purpose of the language. Originally designed by the Council of Europe, a functional-notional approach identifies the functions, or things that can be done through language, for which learners need the language and the notions (i.e., meanings and concepts a learner needs to communicate) that they must handle with it. Categories of functions used to gather data include ordering or requesting, giving instructions, making suggestions, and socializing. The functional-notional approach is closely related to the communicative approach and is learner-centered and self-motivating. A study is reported that focused on need analysis and curriculum design for an ESP program, and particularly concerned an ESP for Food Service in Texas A&M University. Because "order/request" and "instruction" were the most frequently required functions, a curriculum that focused on those two functions was recommended. Examples of appropriate units of study are noted. Contains 8 references. (LB)
