Through a survey of kindergarten senior classes，this study showed that more than half of parents still have concerns about their children’s “school preparation”，among which “learning preparation” is the biggest concern，and there is a utilitarian tendency to “one-sided knowledge preparation”. 80% parents tend to choose subjects for their children and provide guidance，and often use various APPs. The survey also showed that there is a significant correlation between parents’ educational level and understanding of school enrollment policies and these parents’ school preparation concepts and educational behaviors；there is also a great demand for education policy consultancy，inquiries about the situation of grade-one zero-ground education in primary schools，and demand for necessary professional advice and guidance for school preparation. In order to further facilitate the formation of a scientific educational concept and behavior of school preparation，this study puts forward suggestions in four aspects：strengthen policy publicity and guidance to enrich professional connotation；enhance two-way linkage between kindergartens and primary schools to show the effect of “double reduction” to parents；maintain continuous and phased guidance in home education and training so as to cultivate and consolidate the level of core literacy for all and each family；and propose methods for overcoming the difficulties and pain points in early-age reading and writing.
