IB is a high school course offered by IBO (International Bachelor Degree Organization) for students all over the world, and it is also a pre-university course. For two years, the teaching language is English. Its main purpose is to let students receive international education and lay a foundation for further study in world-renowned universities in the future.

All IB diploma students must choose one course in each of the six prescribed subject groups, at least three of which are advanced courses. The maximum score of each subject is 7 points, plus 3 points for expanding papers and knowledge papers, out of 45 points.

Students who want to get IB diploma must also study TOK (knowledge theory) and EE (extended thesis), and have qualified CAS activities (creation, action and service). These three core courses are the concentrated expression of the uniqueness of the curriculum of IBO diploma program.

The course of epistemology is an interdisciplinary compulsory course. Its purpose is to cultivate students' ability of judgment and comprehensive induction, encourage students to question basic knowledge, prevent subjective assumptions and ideological prejudice, and enhance students' ability of analysis and expression on a rational basis.

"Extended thesis" requires students to conduct independent research based on a certain knowledge point in the course they have studied, and can write an article of 4,000 words. This requirement provides students with the opportunity to write papers according to their own interests, which makes them familiar with independent research methods and exercises their writing ability.

CAS stands for creation, action and service, and encourages students to innovate, improve their artistic accomplishment, persist in exercising, care for others and give full play to the spirit of cooperation with others. Only when students surpass themselves and the knowledge in textbooks can they develop in an all-round way and become people with complete civic awareness.
