About Collège Aimé Césaire
The Collège Aimé Césaire is a public secondary school located in Les Ulis, a town in the Essonne department, in the Île-de-France region of France. It welcomes students for the first cycle of secondary education, covering the four levels from sixième to troisième, in accordance with the general organization of the French education system. The school bears the name of Aimé Césaire, a poet, writer and politician from Martinique, a major figure in French-language literature and the Négritude movement, a choice that places the institution within a broader effort of cultural transmission and remembrance.
Situated within the urban fabric of Les Ulis, a mid-sized town known for its residential character and social diversity, the school forms part of the network of public educational institutions in the local area, falling under the jurisdiction of the Versailles academic authority. It serves as one of the local relays of national education policy, receiving students from surrounding primary schools and preparing them for subsequent stages of education, particularly the transition to upper secondary school. Like all public collèges in France, it operates under the authority of the ministry responsible for national education and the Essonne departmental council, which is responsible for managing the buildings and facilities.
The institution's main mission is to provide general education in accordance with national curricula, while also offering pedagogical and educational support to students throughout their time at the school. It also takes part in local educational life, working alongside families, local authorities and other schools in the area, thereby contributing to the continuity of the schooling path for young people living in and around Les Ulis.
The website clg-aimecesaire-ulis.fr is the official website of the school, presenting institutional, educational and practical information intended for students, families and staff of the institution.
