The present work proposes a cross-approach of sociolinguistics and didactics to explore the teaching of languages, especially English, Tamil, Hindi and French, in the Indian context. The study aims at a better understanding of issues on educational management of multilingualism in India while relying on a case study located in Chennai and Puducherry (South India). The inquiry focuses on consistent links between the sociolinguistic situation of India, language education policies, and practices and perceptions of teachers in relation to languages and multilingualism. Linking these different levels of analysis occurs through a process of contextualisation that highlights some specificities of both social and individual multilingualism in India. The research questions more specifically the place of French in the panorama of language teaching in India, as well as related teaching methods and representations. The study of practices and representations of language teachers has been done through a field survey in schools in Chennai, at the Alliance française of Madras (Chennai) and at the Lycée français of Puducherry. This analysis leads to a few suggestions for a better recognition of multilingual practices by the school, so that languages and varieties of the social environment would be taken into account.
