Curriculum We offer a High School international curriculum over three years. Students begin with a preparatory level which helps them improve their level. They are familiarized with a variety of subjects which allows them to choose wisely what will be the core of their studies during the two following years. We also strongly believe that students should be encouraged to develop notions such as international-mindedness, community service and research. They are therefore given the opportunity to participate in various projects which empowers them to develop their sense of compassion, collaborative work and innovation.
