Basic education includes kindergarten, primary school, and junior secondary school, with nine years of compulsory education. Secondary vocational-technical education provides short and medium-term vocational programs. Regular higher education includes undergraduate, graduate, and doctoral degrees. Adult education offers non-formal programs including literacy education and vocational training. China spends about 3.93% of its GDP on education. The country has a literacy rate of 94.2% and uses a semester-based examination system across all levels of education.
