QSI International School of Hangzhou applies the Quality Schools International mastery-based approach in a smaller campus environment suited to Hangzhou's more compact international community. The school serves families across all sectors of the city's international business population.

The mastery approach means students are assessed individually and progress within subjects as they achieve mastery rather than moving as a cohort at a fixed academic calendar pace. This is particularly practical for mid-year arrivals and for students with uneven development across subjects — common situations for internationally mobile children.

Fees are slightly below the Hangzhou International School level, and the school's smaller enrolment creates a closely monitored, personalised environment. Class sizes are deliberately small. College counselling supports US placement primarily; international alternatives are also guided.

Admission requires a foreign passport. The school handles mid-year arrivals throughout the academic year. Mandarin is taught as a core subject.
