First, man is the goal, and the ultimate goal of human education is the free and harmonious development of individuals. Only by respecting the basic human rights and free development of each individual can we conform to the principle of educational equality. Second, the principle of equal education rights. This is relative to political and economic equality. Third, the principle of equal educational opportunities.

A good education system means that everyone has equal learning opportunities, equal treatment and opportunities for success in the education process. Fourth, the principle of differential treatment.

Because the effect of education will vary with the talents, opportunities and opportunities of the educated, equality of opportunities cannot be achieved mechanically, so the realization of educational equality will inevitably treat each individual differently. Education is regarded as a comparative approach to social equality, and through certain education, people will certainly achieve equality in economic or social status, which is the theory of equality.

Among them, the three levels are summarized as: starting point fairness, process fairness and result fairness.

In reality, the issue of educational equity cannot be ignored. Some areas or vulnerable groups have no opportunities for education, which affects their growth and seriously restricts the further promotion of China's sustainable development strategy.

To achieve sustainable development, we must establish and improve the system and mechanism to ensure educational equity, strive to provide citizens with fair educational opportunities and development opportunities, create a good educational environment and competitive environment, and provide reliable talent protection for China's sustainable economic and social development.
