Designing courses for unknown audiences is a very particular task which necessitates course designers to acquire new perspectives from which to see the issues (Dubin and Olshtin, 1988). Course development becomes more demanding especially if it is aimed at international students from different cultural and educational backgrounds. In fact, this is the situation at Universiti Putra Malaysia (UPM) in which 1,846 international postgraduates from 48 different countries are currently pursuing their master and doctorate degrees. Out of this number, nearly a minority of 15% is exempted from UPM English Placement Test if they hold an IELTS (6) or TOEFL (550) certificate. The rest of the candidates are required to register for a prescribed English course which meets six hours a week during a fourteen-week semester. To plan and prepare an appropriate curriculum for such a considerably variant population, the curriculum developers and course designers should primarily diagnose international postgraduates' needs and formulate course objectives so that they meet the audiences' needs (Taba, 1962). Moreover, longitudinal evaluation should be carried out by curriculum and program developers to determine whether their materials and programs continuously meet their students' requirements and expectations or not. To explore perceptions and expectations of UPM international postgraduates regarding their perceptions of the prescribed English course, the whole population of international postgraduates at UPM was emailed an online questionnaire to respond. The questionnaire initiates with a demographical section which is followed by a few yes/no questions to make sure whether a respondent has experienced the prescribed English course or not. The rest of the questionnaire is 22 statements based on a six-point scale (a) to explore perceptions of international postgraduates regarding their teachers, (b) to explore perceptions of international postgraduates regarding their prescribed English course, and (c) to explore international postgraduates' suggestions for the prescribed English course to meet their needs and expectations.
