The language of instruction is a very debatable issue in Morocco. It is rooted in the Moroccan history since colonization period .It has been controversial during the arabization process which has promoted Standard Arabic (SA) as a language of instruction .In recent years, many voices have risen either to question this process in or to support it. Many attitudes have been raised owing to the historical and current factors that surround this issue. The majority of these attitudes are based on theoretical framework, which has become inadequate way of scientific study, especially in a topic like the langue of instruction. This paper tries to cast light on these attitudes and attempts to construct the grounds from empirical fieldwork trough the use of observation and a questionnaire. The informants are 80 university students of English studies and Islamic studies. The main findings lie in the gap between theoretical and empirical research, the necessity of SA use as a language of instruction in many fields, such as: Islamic studies, the possibility of using reduced Arabic in other domains.
