This article is concerned with research on the sociolinguistic reality in Algeria, by studying one of its issues, which is the issue of the arabization of education. And if the linguistic policy is affected and influenced by social life, then planning in arabization has a relationship with social reality. Therefore, our research aimed at studying the relationship between the applied arabization policy and the linguistic requirements of social reality. The most important results reached were the inconsistency of the applied arabization policy with the linguistic base established by the colonial authority , which continued after independence, and led to the emergence of fundamental problems, resulting from the total arabization of the basic and secondary training and some specializations in higher education. So that students in arabized disciplines largely lost control over the foreign language, which is a prerequisite for contemporary changes and for national needs that require control over bilingualism. As for those enrolled in specializations that depend on the French language, they found difficulty with the language of formation, because their basic formation was in the Arabic language.
Keywords: The Policy of Arabization , Higher Education, Language Planning, Social Reality, Undergraduate Student.
