Education equity is mainly C, which guarantees citizens' right to education according to law. Specifically, it can be understood that educational equity is a historical category with different meanings in different countries and historical periods. It is not only a reflection of social reality, but also a transcendence of social reality. It is the unity of social reality and educational ideal, and has specific historical significance, including its historical rationality and historical limitations. We can define educational equity in this way: the so-called educational equity refers to the rational norms or principles on which the state allocates educational resources. "Reasonable" here refers to the unified allocation of educational resources from the dialectical relationship between the overall development and stability of society and the individual development needs of social members. Specifically, the connotation of educational equity can be divided into three levels: (1) ensuring that everyone enjoys equal rights and obligations to receive education; (2) Providing educational opportunities and conditions in relatively equal; (3) Educational success opportunities and educational effects are relatively equal, that is, after receiving the same level of education, every student can reach a most basic standard, including substantive fairness in students' academic achievements, fairness in education quality and equality at the goal level. Among them, "ensuring everyone has the opportunity to receive education" is the premise and foundation, "providing educational opportunities and opportunities are relatively equal" is a further requirement, and it is also the premise of "educational success opportunities" and "educational effects are relatively equal". Generally, these three levels can be summarized as: starting point fairness, process fairness and result fairness.
