This paper focuses on the core issues of students’ personalized development from the perspective of educational equity and examines its real difficulties. The imbalance of resource allocation leads to a weak foundation for fair personalized development. Standardized teaching causes the loss of fairness during the learning process. Biased evaluation results distort fairness in learning outcomes. Based on these problems, this paper proposes targeted support strategies. These include building a fair foundation through balanced resource allocation, shaping a fair learning process through personalized teaching models, and achieving fair outcomes through a diverse evaluation system. The study aims to offer ideas to solve the challenge of coordinating educational equity and personalized development and to help every student receive fair and suitable development support.
