Abstract: Faced with different educational justice theories, it's essential that we study Marx's theory of educational justice in order to choose and use it to guide the education practice. Although Marx did not write articles and works on educational justice, he devoted himself to studying the law of social development and created the theory of all-round development of human being. This is the pre-conditional thought of educational justice theory. A clear boundary between Marx's theory of educational justice and other educational justice theories is presented in this paper. It involves the premise of educational justice, the evaluation of educational justice and path to the realization of educational justice.

Key words: Marx's educational thoughts, justice, educational justice theory
