Sector worth $117b caters to meet demands of 140 million students

Private tutoring for primary and middle school students has become a huge, financially lucrative market, a survey shows.

Conducted by the Chinese Society of Education and released last month, the survey reveals that private tutoring revenues reached 800 billion yuan ($117 billion) in 2016, covering almost 140 million students. An estimated 7 million teachers, employed by the agencies, serve the students.

About 40 percent of the teachers surveyed teach math at the agencies, while those teaching English and Chinese separately account for 20 percent. Eight out of 10 teachers surveyed hold a bachelor's degree and 60 percent studied normal or education-related majors at college.
