The System of Education in Morocco is in Arabic till high school, whereas higher education is still conducted in French (for scientific subjects alone, literary studies are carried out in Arabic). The shift of the medium of instruction from Arabic to French may hinder students' achievement at the university and other related institutes. This division of the system of education may result in having two types of graduates: Frenchified ones who may get lucrative jobs and Arabized ones left with not well paid ones. By investigating the implications of Arabizing the system of Education on the level of achievements of first year students at the university, this research tries to shed light on a more complex issue which is the ability of these faculties to provide good quality graduates who are able to contribute to the development of the country. It attempts to investigate the impact of the shift in the medium of instruction from Arabic to French on students’ achievements at the university and to look at the impact of Arabizing the system of education up to high school on the quality of university graduates, and to what extent such plan has promoted the sector of higher eduction.
