About Lycée professionnel Gilbert Courtois
The Lycée professionnel Gilbert Courtois is a public secondary education institution located in Dreux, in the Eure-et-Loir department, in the Centre-Val de Loire region of France. It belongs to the network of local public education establishments overseen by the French Ministry of National Education and forms part of the network of vocational high schools within the Dreux area, contributing to the technical and vocational training offer of the territory.
The institution is named after Gilbert Courtois, in tribute to a local figure, following a common practice in French schools of naming establishments to honour individuals who have marked the educational, social, or professional life of a town or region. The school enrolls students preparing vocational education diplomas, within the framework of programmes offered by the National Education system, in connection with the qualification needs of the local employment area. Like most French vocational high schools, it combines general and technical instruction with periods of workplace training designed to facilitate students' integration into working life or further studies.
Located in Dreux, a mid-sized town in the Eure-et-Loir department, the institution is part of the local educational fabric alongside other schools in the town and its surrounding area. Its scope of activity mainly concerns students from the recruitment area of Dreux and its surroundings, reflecting the proximity-based organisation characteristic of vocational education in France. The institution thus participates in the missions of training, guidance, and support for young people toward qualification and employment, missions entrusted to vocational high schools within the national education system.
The website lyceegilbertcourtois.com is the official website of the institution, presenting information about its organisation, training programmes, and school life.
