About Lycée polyvalent Eugénie Cotton

The Lycée polyvalent Eugénie Cotton is a public secondary education institution located in Montreuil, in the Seine-Saint-Denis department, within the Île-de-France region of France. Operating under the authority of the French Ministry of Education and attached to the Créteil académie, it enrolls students pursuing upper-secondary level studies within the French educational system. Its location within the urban fabric of Montreuil makes it a local institution serving families from the town and surrounding areas. The school is named after Eugénie Cotton, a French physicist and prominent figure in the associative and educational movements of the twentieth century, recognized for her role in promoting women's access to scientific studies as well as for her involvement in the French Resistance and post-war associative life. The choice of this name reflects a republican tradition of honoring, through school names, individuals who have shaped the social, scientific, or political history of the country. As a "lycée polyvalent," the institution offers a diversified range of educational tracks, typically combining general, technological, and vocational streams, allowing students to follow varied paths according to their educational and career plans. This diversity makes it a significant actor in the local educational landscape, contributing to the training of younger generations and preparing them for higher education or professional integration. Like other secondary institutions, the school also participates in the public education missions defined by academic authorities, including pedagogical support, student guidance, and school life management. The website lyceecotton.net is the official website of the institution, presenting information about its organization, its educational offerings, and school life.
