Supporting socio-economically disadvantaged students to improve their academic resilience is vital in promoting social mobility and halting intergenerational transmission of poverty. Based on the baseline data 2013-2014 from the China Education Panel Survey (CEPS) database, this paper examined the impact of preschool education experience on academic resilience of disadvantaged students using coarsened exact matching (CEM) and hierarchical logistic regression. Research findings show that disadvantaged children have less access to preschool education than their advantaged peers, with a kindergarten attendance rate lower than 70%; that preschool education can significantly improve children's cognitive ability and effectively predict academic resilience of disadvantaged students; and that preschool education is a better predictor of resilience of rural disadvantaged students than that of their urban counterparts. The government should reinforce subsidies for early childhood education that can serve as compensation for disadvantaged kids; and should further universalize preschool education to secure the opportunity of high-quality pre-primary school education for disadvantaged children.
