Before 2013，despite the chronic pressure on population control，the size of migrant population in Beijing and migrant children in public schools both continued to rise. Since 2014，as the central government gave instructions for strict control of Beijing’s population，considerable barriers for non-Beijing students （those who do not have Beijing Hukou）to receive compulsory education have been set up. Therefore，the enrolment rate of migrant students has declined significantly. As the high school entrance examination and college entrance examination are still not open to non-Beijing students，more than 40 percent of non-Beijing junior high school students can not complete their studies in Beijing，but have to leave for their hometown outside Beijing for further studies. In 2016，although frequent policy reforms on household registration take place，the government-led curbs on population remain. Migrant children in Beijing will still face great challenges in finishing compulsory education，and a great number of them will be forced to leave Beijing every year and become left-behind children in their hometown.
