Where do migrant children go after they complete compulsory education？How are their education and employment conditions？This essay analyzes these questions based on the survey data of five consecutive years acquired from 1866 second-year middle school students from fifty non-governmental schools in ten districts of Beijing. Analysis results show that （1）The overall level of education achievement of migrant children group is low. Less than 40% of the students continue senior high school education （including vocational high school education）. Less than 6% of the students go to college. Among those who go to high school，more students choose to go to vocational high schools than common high schools. Among those who go to college，nearly half of them choose independent colleges or higher vocational education. （2）Migrant children do not have satisfying performance in both the level and quality of employment. Two thirds of the students who are employed work for low-end service industries. Their average monthly salary is about 2500 to 3000 RMB. Around 10% of the students are self-employed. About 13% to 21% of the students are unemployed. （3）The majority of migrant children choose to stay in Beijing. These include over two thirds of those who go to vocational high schools，nearly thirty percent of those who go to college，and three fourths of those employed or unemployed. （4）This population have started entering marriage and child upbringing，which means migrant children have started “reproduction.” The essay analyzes the institutional causes that lead to severe education and employment challenges of migrant children and then offers relevant policy suggestions.
