Language management in Cameroon and its challenges for the Cameroonian school is an always topical subject, more than fifty years after reunification. The formalization of French and English helped relegate local languages to a domestic role. What has caused the death of several of them. To preserve the national heritage, and promote these languages, the Government has decided to introduce them into education. The words of this article, built from the perspective of linguistic development and which is essentially based on field investigations and a multidisciplinary approach, is to analyze the implications of the teaching of the national languages in school, under the perception that children have of the languages of their environment. On the one hand, the results obtained show that representations and family attitudes towards native languages have consequences on representations and attitudes of students towards these languages, and their level of proficiency in these languages; On the other hand, students place great importance to the status of languages. It thus follows the need to legitimize the relationship with these native languages to promote the success of such an undertaking.

The balance of policy development implementation in Africa since the 1970s is quite mixed. The development is not the only economic growth function. It constitutes a means to access an intellectual, emotional, moral and spiritual existence. This participates to indicate that as such, development is indivisible of culture. Today, it is increasingly found that, it is a development rooted in the culture, and sensitive to local context which is in fact likely to be sustainable. The objective of this reflection is to raise the fundamental place that must occupy the culture in the process of Cameroon's development, and suggest the mechanisms by which it could actually be incorporated into the national project of emergence. This work is mainly based on an empirical analysis of international institutions' documents, and the experience of countries that have emerged in relying on their culture throughout the world. We hypothesize that the identification of social cultural models and their taking into account in the formulation of the policy of Cameroon's development could be significant asset to the achievement of an inclusive and sustainable development in Cameroon. Clearly, these procedures may allow Cameroon to take into account local cultures in the national development project long term. It is education and enhancement of local languages.
