Beijing - School Report Question and Answers
What is the approximate teacher-to-student ratio in the grades that your child attended?
In middle school and up it is 18 to 1, but in the high school that drops to a lower number for some classes. One of my kids has an IB class with only 3 students and really enjoys it. - Mar 2021
it seems to be anywhere from 5 to 20 for a high school class. - Apr 2018
