About Lycée polyvalent Langevin Wallon
The Lycée polyvalent Langevin Wallon is a public secondary education institution located in Champigny-sur-Marne, in the Val-de-Marne department, in the Île-de-France region of France. Its name pays tribute to Paul Langevin and Henri Wallon, figures associated with reflection on the democratization of education in France during the 20th century. The institution is part of the network of public schools under the French Ministry of Education and enrolls students from the local catchment area as well as, depending on the tracks offered, from a wider geographic area.
As a polyvalent lycée, the institution offers several educational pathways, combining general, technological, and vocational education, allowing it to accommodate a variety of academic and career orientations within a single structure. This organization reflects an approach to secondary education aimed at providing diversified pathways, ranging from the general baccalaureate to technological and vocational programs, as well as, where applicable, post-baccalaureate sections. Its location in Champigny-sur-Marne is part of a broader history of the development of public school facilities in the eastern Paris area during the second half of the 20th century, a period during which several institutions named after figures linked to education were established.
The lycée occupies a place within the educational network of Val-de-Marne, complementing other secondary institutions in the area. It takes part in the general missions of public education: transmitting knowledge, preparing students for national examinations, supporting orientation pathways, and overseeing the school life of enrolled students. Like any French polyvalent lycée, its operation relies on national regulatory frameworks while adapting to the local specificities of its recruitment area.
The website lycee-langevin-wallon.com is the institution's official website, presenting its educational tracks, pedagogical organization, and various practical information intended for students, families, and staff.
