To explore the impact of parenting efficacy and parenting styles on academic achievement of students, this article studies 168 rural parents and children from Henan, Hunan, and Hubei using the questionnaire survey method. The results show that rural parents have a good sense of parenting efficacy and parenting style in general, but there are significant differences in child gender, child grade, parental gender, and parental age. A significant correlation between the parenting efficacy, parenting style, and academic achievement of students is observed. The parenting styles of rural parents, such as “dictatorship and democracy”, “punishment and motivation”, and “rejection and acceptance”, can serve as partial mediating variables between parental parenting efficacy and academic achievement of students, and effectively predict academic achievement of students.
