This chapter explores the nature of these differences. Using available evidence on Wuhan, Xiamen, Shanghai, and Guangzhou, it starts by pointing to key areas in which municipal policy approaches can diverge, illustrating the importance of examining the effects of decentralization in different localities. The chapter brings together for the first time the body of published and grey literature, complemented by primary fieldwork, to provide a more comprehensive picture of the policy history of migrant children's education at the central and particularly Beijing municipal levels. Such measures indicate efforts by the municipal government to reduce its share of the responsibility, potentially shedding light on the extent to which it sees migrant children's education as a policy priority. One exception can be found in the "Notice of the Beijing Municipal Education Commission on the Work of Strengthening the Management of Self-Run Migrant Schools", which calls for a three-part strategy that includes assisting some schools.
