Some excerpts:

While China has phenomenally expanded basic education for its people, quadrupling its output of college graduates in the past decade, it has also created a system that discriminates against its less wealthy and well-connected citizens, thwarting social mobility at every step with bureaucratic and financial barriers.

A huge gap in educational opportunities between students from rural areas and those from cities is one of the main culprits. Some 60 million students in rural schools are “left-behind” children, cared for by their grandparents as their parents seek work in faraway cities. While many of their urban peers attend schools equipped with state-of-the-art facilities and well-trained teachers, rural students often huddle in decrepit school buildings and struggle to grasp advanced subjects such as English and chemistry amid a dearth of qualified instructors. “Rural students stand virtually no chance when competing academically with their urban counterparts,” ....

One researcher showed that an applicant from Beijing was 41 times more likely to be admitted to Peking University than a comparable student from the poor and largely rural province of Anhui.

Even an urban residency status doesn’t ensure educational equity among city dwellers. The quality of urban schools varies widely, and the competition to enter top schools has spawned rampant corruption. Parents fork out tens of thousands of dollars under the guise of “voluntary donations” to secure a slot for their children in elite schools.

In China, which pioneered the use of merit-based examinations to fill official positions, an educational system that was once a great equalizer now reinforces inequality.
