SIS Swiss International School is a private educational institution that is financed solely from school fees and does not receive subsidies from the Swiss national or cantonal governments. We offer high-quality education as a service – and we are committed to offering this service in a transparent way.
School Fees 2025/26
The school fees are billed in advance per semester. On request, arrangements can be made to pay the school fees in monthly instalments. School fees for mid-term admissions are prorated.

*Primary intro: We encourage but do not enforce full-time attendance. To fulfil cantonal regulations, a minimum of 22 lessons per week is required. Each student must attend a minimum of four mornings per week (two German and two English). The remaining lesson requirements must be made up with a fifth morning and/or afternoon lessons, to be agreed between the parents and the school.

All students have the option of signing up for a hot lunch. The children are supervised throughout the lunch break. Lunch can be ordered on a semester or daily basis.

Before- and After-School Care (optional)
Before- and after-school care is offered in cooperation with FitzGerald Bilingual Day School. The children receive breakfast during morning supervision and a snack in the afternoon.

Children are supervised by a member of staff at all times.
