The projects requires each student to create a personal «Chef d’oeuvre», which must include artistic, technical, practical, and written components. Each student therefore freely chooses a transdisciplinary subject. The student is supported and accompanied by a mentor throughout the year. It ends with a presentation of the project before a jury followed by an exhibition in the school. The Chef d’Oeuvre thus allows to «decompartmentalize» the subjects and to involve the pupils in the process of learning by broadening their horizons.
