About Lycée polyvalent Jacques Cartier
The Lycée polyvalent Jacques Cartier is a public secondary education institution located in Saint-Malo, in the Ille-et-Vilaine department of France. Operating under the French Ministry of National Education, it enrolls students at the upper secondary level, offering general, technological, and vocational programs, in line with the purpose of a so-called "polyvalent" lycée, a structure designed to diversify the educational pathways available to students within a given catchment area.
The institution takes its name from Jacques Cartier, a navigator and explorer born in Saint-Malo, a historical figure associated with the sixteenth-century exploration of the Saint Lawrence River. This choice of name situates the lycée within the maritime and historical identity of the corsair city, where several public institutions likewise bear the names of figures connected to navigation and exploration. The lycée offers a range of tracks leading to different qualifications, including the general baccalauréat, the technological baccalauréat, and vocational training programs, enabling students to pursue higher education or enter directly into professional life depending on the path followed.
As a public institution, the Lycée Jacques Cartier forms part of the network of secondary education establishments in the Saint-Malo area, contributing to the local educational offering alongside other schools in the region. It participates in the public service missions of education, such as the transmission of knowledge, preparation for national examinations, student guidance, and support toward higher education or entry into working life. Its reach extends beyond the municipality itself, as it enrolls students from various surrounding communities within the wider Saint-Malo area.
