Recently, someone put forward a proposal to extend the nine-year compulsory education to twelve-year compulsory education, which aroused everyone's concern and related discussion. ..... Different people have different views on whether 12 year compulsory education is necessary. Personally, I think this is necessary. Specifically, the reasons include three aspects: the extension of the period of compulsory education can effectively improve people's knowledge level, and the 12-year compulsory education can help those who receive education to have a stronger level of professional skills. The relevant conditions for implementing the 12-year compulsory education are now available. 1, the extension of compulsory education years can effectively improve people's knowledge level. The reason why a person wants to receive education is to learn knowledge and improve his knowledge level. Compulsory education is the most effective educational measure. The extension of compulsory education can make people have a longer time to receive education and enrich their knowledge, which is of greater benefit to each of us. 2. Twelve-year compulsory education can make the educated have a higher level of professional skills. Twelve-year compulsory education has included senior high school in compulsory education. Therefore, for those who receive compulsory education, this situation will enable them to study all subjects more systematically, so that they can master basic knowledge and professional knowledge more comprehensively, so that those who receive education can have higher professional skills and provide greater help for their future development. 3. At present, the conditions for implementing 12-year compulsory education have been met. After the implementation of nine-year compulsory education for many years, the relevant resources have been very rich. At present, the conditions for further extending the time of compulsory education and implementing 12-year compulsory education have been met. ..... Therefore, the implementation of 12-year compulsory education has many advantages and related conditions. At present, measures can be taken to promote and gradually extend the nine-year compulsory education to 12-year compulsory education, so as to improve the quality of education and provide more favorable conditions for social development.
