Business schools in Asia frequently use English as the medium of instruction. One such school is the School of Business and Management (SBM) of the Bandung Institute of Technology (ITB) which is recognised as one of the leading business schools in Indonesia. Doubt had been expressed whether under current English language (EL) entry requirements students have sufficient competence to complete course requirements satisfactorily. This research, limited to postgraduate programmes, concluded that indeed most students lacked the EL skills to perform well. Some suggestions for remedial action are offered.
