Nine-year compulsory education tuition is free. According to the revision of the Compulsory Education Law of People's Republic of China (PRC), the state clearly stipulates the implementation of free nine-year compulsory education, which means that every child has the right to receive free compulsory education without worrying about tuition fees. This policy includes waiving tuition fees and book fees, and providing cost of living allowance to boarding students with financial difficulties. The nine-year compulsory education system is a unified education system implemented by the state. All school-age children and adolescents must enjoy the right to receive compulsory education, which is a public welfare undertaking that the state must guarantee. The implementation of nine-year compulsory education means that school-age children and adolescents begin to receive nine-year education without tuition and fees. The state establishes a mechanism to guarantee the funds for compulsory education to ensure the implementation of the compulsory education system. Nine-year compulsory education is the current education system in China.
