Students at HFI follow a rigorous college-preparatory curriculum. HFI’s program is based on an American curriculum, supplemented by traditional Chinese courses and supported by high-quality teaching, testing standards, and academic procedures. All classes at HFI are taught by professionally credentialed teachers, the majority of whom are native English speakers. In Grades 9 and 10, students take both pre-AP courses and approved Chinese high school subjects. Classes taught in Chinese are highly rigorous; such as mathematics, are more advanced than the AP Calculus curriculum. In Grades 11 and 12, students follow an intensive AP curriculum, with an English course, at either Standard or AP level. To broaden academic offerings beyond the AP program, the school provides additional subjects such as Philosophy, Logic, Sociology, Film Studies, Drama, Advanced Calculus, and Linear Algebra, which are equivalent to second-year university mathematics courses. In Grades 9 and 10, the primary language of instruction is Chinese (except for English classes); in Grades 11 and 12, instruction is primarily in English. Courses such as English for Academic Purposes, Introduction to History, and Introduction to Musical Theater are exclusively offered to students in the four-year program.
