Public school prepares students for official tests. Specifically, the ZhongKao (High School Entrance Examination) in 9th Grade and GaoKao (College Entrance Examination) in 12th grade determine whether a student can go to high school and university, and which school can they apply to register. These tests are high stakes, as they often determine future career design, job opportunities, social standing, etc.
Recently, there have been independent businesses that run enrichment programs at these high schools. While it is rare for a foreign teacher to be employed directly by the government as a public school teacher, it becomes a common case for a foreign teacher to work at a public school with an office at campus, teach all students at that school, in the ZhongKao or GaoKao curriculum, and yet simply be paid and managed by a private company. Having teaching jobs in Chengdu are good.
