Best IB Schools in Zurich
If you’re settling in Zurich and have your heart set on your children studying within the IB, Zurich fortunately has several schools offering International Baccalaureate programmes. However, their provision varies. Some offer the Diploma Programme only, while others provide an IB pathway from the early years through to graduation. When comparing the best IB schools in Zurich, you should consider the programme offered, your child’s age, the language of instruction you desire, the location and the fees.
This guide compares the main IB schools in Zurich and the surrounding area to help you understand the main differences before arranging school visits.
The Best IB Schools in Zurich
Here’s a quick look at the schools covered in this guide:
- Inter-Community School Zurich (ICS)
- Zurich International School (ZIS)
- SIS Swiss International School Zürich
- Academic Gateway
These four schools take quite different approaches to the IB. ICS runs the full continuum from the Primary Years Programme through to the Diploma. ZIS and SIS Zürich both offer the Diploma Programme but combine it with other pathways. ZIS also offers AP and school-developed courses, while SIS allows students to work towards the Swiss Matura alongside the IB Diploma. Academic Gateway, by contrast, is a smaller, upper-secondary school built specifically around the final two years of the Diploma. Below, we’ve broken down what each one offers.
Inter-Community School Zurich (ICS)
ICS, based in Zumikon, is the only school in this guide to offer all three IB programmes: the Primary Years Programme (PYP), the Middle Years Programme (MYP) and the Diploma Programme (DP) as an authorised IB World School. It educates children from around age 2 through to 18, so a family can remain at the same school from nursery through to their child’s final examinations.
The school has around 800 pupils from more than 50 nationalities. Teaching is in English. Its most recently published average IB Diploma score is 34.5, while around a third of students work towards an IB bilingual Diploma.
ICS tends to attract families who place a high value on continuity. If you’re relocating with younger children and expect to stay in Zurich for several years, avoiding another secondary school search and application process later on can take a lot of pressure off.
Zurich International School (ZIS)
ZIS operates across two campuses, in Wädenswil and Adliswil, and teaches roughly 1,300 students aged 3 to 18. It’s an authorised IB World School for the Diploma Programme. It also offers Advanced Placement (AP) courses and its own ZIS-developed courses in Grades 11 and 12, giving students greater flexibility when selecting their senior courses.
Its most recent results show a 98% Diploma pass rate and an average score of 35, with 40% of candidates earning an IB bilingual Diploma. German is taught through to Grade 9, after which it becomes optional, and the school also runs a separate bilingual pathway alongside its international curriculum for younger year groups.
ZIS may appeal to families looking for strong examination results and the flexibility to combine IB and AP subjects.
SIS Swiss International School Zürich
SIS Zürich, in Wallisellen, teaches bilingually in English and German from kindergarten onwards. During the final two years of its bilingual college, students can work towards the IB Diploma, the nationally recognised bilingual Swiss Matura or both qualifications. The combined route is academically demanding but prepares students to apply to universities in Switzerland and abroad.
The IB Diploma Programme is also open to students who transfer from other schools, local or private, provided they meet the academic and English-language requirements. SIS states that applicants should have completed lower secondary education and, ideally, one or two years of “college” elsewhere.
This school is ideal for families planning to remain in Switzerland or those who want their child to study in both German and English while keeping international university options open.
Academic Gateway
Academic Gateway, based in Zurich, is a smaller school serving a narrow age range: students join at 16 and complete the IB Diploma by 18. Unlike the other schools in this list, it isn’t a continuous school from early years. Instead it functions as a dedicated upper-secondary option with a unique approach to independent study: ideal for those looking for high flexibility and autonomy.
The school currently lists the complete two-year programme at CHF 68,000, equivalent to CHF 34,000 per year if the cost is divided evenly. Academic Gateway may be a practical choice for teenagers moving from another curriculum into the IB Diploma Programme. It provides a more focused, exam-oriented environment than the larger all-through schools.
Before deciding on any of these options, families need to consider the additional details that will shape the day to day experience at each of these schools. Admissions policies, subject availability and language support can vary, even when schools offer the same IB programme. The daily journey matters too, particularly when campuses are outside central Zurich or children depend on school transport. Ask whether the preferred Diploma subjects run every year, how timetable clashes are handled and what academic or language support is available.
Visiting the campus can help you compare class sizes, facilities and the atmosphere. These practical details often make the difference between two schools that appear similar on paper.
Why Choose an IB School in Zurich?
The IB isn’t the only curriculum available to international families in Zurich, but there are a few reasons it remains a popular choice.
- Recognition: the IB Diploma is accepted by universities across Europe, North America and beyond, which is helpful if your child hasn’t decided where they want to attend university.
- Continuity: for families who move countries every few years, the IB’s consistent framework can make switching schools less disruptive than moving between national systems.
- University preparation: the combination of coursework, exams and the Extended Essay gives students practice with the kind of independent research expected at degree level.
- Critical thinking: subjects like Theory of Knowledge push students to question sources and assumptions rather than simply memorise content.
- A multicultural environment: IB schools in Zurich tend to draw families from dozens of nationalities, which can ease the adjustment for children arriving from abroad.
- Language exposure: several schools on this list, including SIS Zürich and ZIS, build German into the timetable alongside English, helping children develop their local language skills. Many also are able to support School-Supported Self-Taught languages as part of the IB Diploma for students who want to pursue their native or other language.
The IB is only one part of the wider picture, though. Zurich also has schools following British, Swiss and bilingual curricula that might fit your family better, depending on your circumstances. For a broader comparison, our guide to the best international schools in Zurich covers IB, British and bilingual options side by side.
How Much Do IB Schools in Zurich Cost?
Annual tuition ranges from around CHF 31,000 to CHF 40,000 for Diploma years. Academic Gateway lists its complete two-year programme at CHF 68,000, while ZIS charges CHF 39,700 annually for Grades 11 and 12 in 2026/27. Fees vary by school, year group, programme and the services included.
Tuition doesn’t always include every expense, so parents should check whether the following costs are charged separately:
- application or registration fees;
- capital or infrastructure contributions;
- transport;
- lunch;
- extracurricular activities;
- external examination fees.
These charges can increase the overall cost, particularly during a student’s first year. See our guide to International School Fees in Zurich for a fuller comparison.
