Sister Schools
Students can study at our sister schools (high schools) without paying local tuition and can earn credit for up to one year of academic work. In addition, our special relationships with the universities listed below give our students opportunities to engage in focused study on sustainability issues and to interact in English with peers from all over the world in unique summer programs.
