By analyzing the basic condition of the migrant children’s compulsory education in the Pearl River Delta during 2013-2015，this report discovers that the number of migrant children in the Pearl River Delta has been increasing rapidly over recent three years，among which more than 60% have migrated to Shenzhen，Dongguan，or Guangzhou. Less than half of the migrant children study in public schools. Promoting the points-based household registration system and developing non-governmental schools are the two main policies for the migrant children to study in school. Facing the problems including the shortage of supply of education resources in the Pearl River Delta，the invisible exclusion policies of some cities and the uneven education quality in non-governmental schools，this reports points out that expanding public schools should be comprehensively included in the core work of education development projects. A new financial system that governments at all levels share education inputs needs to be established and provincial governments should strengthen the overall planning capability in compulsory education. The report also suggests governments to comprehensively purchase high-quality education services from non-governmental schools.
