Twelve-year compulsory education refers to the provisions made by the state on the length of compulsory education for students, that is, from the first grade of primary school to the end of the third grade of high school, a total of twelve years. The implementation of this system can effectively improve the level of national education, cultivate more knowledge and skills, and make contributions to the development and progress of the country.

Of course, there are also some problems and challenges in the implementation of twelve-year compulsory education, such as uneven distribution of educational resources, uneven quality of education, unreasonable curriculum and so on. These problems need constant reform and improvement to improve the quality and fairness of education.

Generally speaking, 12-year compulsory education is necessary, which can provide more educational opportunities and development space for students and is of great significance to the future of individuals and countries.
