Curriculum and academics
SIS Swiss International School Zurich teaches bilingually in German and English from the earliest years, so a child grows up using both languages across the curriculum rather than studying one as a foreign subject. In the primary grades the teaching follows the cantonal framework alongside elements of an international curriculum and the school's own SIS materials, with language support built into everyday lessons. The senior school, known as the SIS Bilingual College, leads to the International Baccalaureate Diploma, a broad qualification recognised by Swiss universities, the federal institutes of technology and universities worldwide.
A distinctive feature of the Zurich school is that the Bilingual College runs the IB Diploma alongside a route toward the bilingual Swiss Matura, so families can choose an international qualification, a Swiss one, or in some cases prepare for both. For how it sits against the other Diploma schools in the city, the best IB schools in Zurich guide and the Zurich IB hub set out the comparison.

SIS Swiss International School Zurich fees
SIS Swiss International School Zurich fees sit in the mid to upper part of the Zurich international school fees range. Published annual tuition has been quoted in the region of CHF 26,000 to CHF 31,000 depending on the year group, with the lower years toward the bottom of that band and the senior college toward the top. Treat that as an indicative range rather than a quote, as schools review fees each year.
As with any full fee private school, budget for costs beyond tuition. These usually include a one off registration or enrolment charge, a deposit, and extras such as lunches, trips, materials, examination entry in the senior years and any bus service. Confirm the current tuition and the full list of ancillary charges with the admissions office before you apply, as these change annually and vary by stage.
Admissions
SIS runs admissions through its own office, reviewing prior school reports and meeting the family before a place is offered. Because the programme is bilingual from the start, the school looks at a child's age, school history and language background to judge the right entry point, and younger applicants joining in kindergarten or early primary typically settle into the two languages most naturally.
Places in popular year groups can be limited, so it is worth contacting admissions early to confirm availability in the relevant stage and, for the senior years, that the intended Diploma or Matura pathway will run. Families relocating to Zurich should also allow time for the residence paperwork a move to Switzerland involves.
Location and who goes there
The school sits in Zurich-Wollishofen on Seestrasse, between the city centre and the western shore of Lake Zurich, an area within easy reach of the city's tram and rail network. The wider SIS Switzerland network runs further campuses in the greater Zurich area, but this profile covers the Wollishofen school.
