With the large-scale migration of the population and the migration of migrant workers into cities, migrant children’s education has become one of China’s current important issues in education. The paper first reviews the evolution of migrant children's education policies in China and the latest developments in related policies. It also introduces the family education issues and social issues of migrant children and presents the basic overview of migrant children education. The second part of the paper focuses on the specific content of compulsory education for migrant children. These include new conditions and new problems in pre-school education, high school entrance examination policies and compulsory education for migrant children in different regions. In megacities such as Beijing, Shanghai, and Guangzhou, the policy of “controlling the population through education” has emerged as a result of the reduce policy to the number of people, which has greatly affected the educational accessibility of migrant children. After 2014, the cities of the Yangtze River Delta, the cities of the Pearl River Delta, and other provincial capital cities have begun to implement a residence permit system, and have set points for admission and points for entry. From the actual situation, this is mainly for highly educated and high-income group, low-educated and low-income migrant workers and their children cannot get the benefits which they deserve from this system. The point system not only fails to provide sufficient educational resources for public schools but also does not allow private schools (migrant children schools) to further develop. The final part of the paper discusses the policy of reforming migrant children's education and also analyzes the different opinions of different scholars. At the end of the article, I put forward my views on the issue of migrant children's education, and suggest a more fundamental way to solve such problems.
