Vienna sits at the centre of one of Europe's largest diplomatic communities, with the United Nations, OPEC, OSCE and IAEA all headquartered in the city. The result is a strong international school sector that combines the major IB and American institutions with French and other national schools, and a long tradition of admitting expat children with multilingual backgrounds.
If you are relocating to Vienna in 2026, this step-by-step guide walks through the admissions process: timelines, required documents, language assessments, fees in EUR, and how to maximise your chances at the most competitive year groups.
How the Vienna admissions calendar works
Most international schools in Vienna follow a September academic year and run a structured admissions cycle:
- Main wave (October to February) for September entry. Apply by January at the latest for the most competitive year groups.
- Late wave (March to June) for families relocating mid-year. Some schools maintain rolling waitlists year-round.
- Summer wave (July to August) for last-minute relocations — feasible at smaller schools but not at the largest IB schools.
Diplomatic family rotation is concentrated in summer, so August and September places open up unpredictably as outgoing families finalise their moves.
Required documents for Vienna international schools
Plan to gather these documents at least 60 days before applying:
- Apostilled birth certificate, translated into German or English if needed
- Last two years of school reports translated into English or German
- Vaccination record matching Austrian national requirements
- Copies of passport, residence permit (Aufenthaltstitel) or diplomatic ID
- Proof of Vienna address or rental contract
- Recent standardised test scores (MAP, CAT4, ISEE) where requested
- Reference letter from the current head teacher for Year 7 and above
- For diplomatic and UN family applications: a copy of the assignment letter
Most schools also request a short student-led interview, usually conducted via Zoom for families still abroad.
Top international schools in Vienna and their admissions process
Vienna International School
Vienna International School (VIS) is the city's flagship IB school, founded in 1959 to serve UN diplomatic families. It offers all three IB programmes (PYP, MYP, DP) and gives priority to UN-affiliated families, but maintains around 30% non-diplomatic intake. Admissions include CAT4 testing and an interview with the relevant principal.
American International School Vienna
The American International School Vienna (AIS) follows a US curriculum from Pre-K to Grade 12, with the IB Diploma in the senior years. AIS uses MAP testing for placement and runs an in-person assessment and interview for all applicants from Grade 3 onwards.
Danube International School Vienna
Danube International School Vienna (DISV) is a smaller IB World School in the second district. The school is known for personalised attention and accepts mid-year transfers more readily than VIS. Admissions include a written assessment, a parent interview and a short student-led trial day.
AMADEUS International School Vienna
AMADEUS International School Vienna combines a full IB Continuum with one of Europe's strongest music programmes — the school operates as a regular IB school plus a separate Music Academy stream for students with conservatoire-level potential. Admissions include both academic testing and an audition for the Music Academy track.
International Christian School of Vienna
The International Christian School of Vienna (ICSV) follows an American curriculum from Pre-K through Grade 12 with the IB Diploma optional in the upper school. The school is faith-based but admits non-Christian families and runs a less competitive admissions process than VIS or AIS.
Language assessments and EAL support
Most Vienna international schools teach in English and expect children entering from Year 3 onwards to be functional in the language. Common assessments:
- WIDA or Oxford Online Placement for English readiness
- CAT4 for cognitive and reasoning benchmarks (used by VIS and DISV)
- MAP Growth for maths and reading levels (American curriculum schools)
If your child does not yet have native English, look for schools with embedded EAL support — VIS, DISV and ICSV all offer structured English-as-an-additional-language tracks. Most schools charge an additional €2,500 to €4,500 per year for individualised language support.
Fees and registration costs
Vienna sits in the middle of the European fee range — significantly cheaper than London and Paris but more expensive than Lisbon or Berlin. Realistic 2026 figures:
- Application fee: €150 to €350
- Capital levy / enrolment fee: €1,500 to €5,500
- Annual tuition: €15,500 to €23,500 for primary, €19,500 to €27,500 for secondary, with the IB Diploma at the upper end
- Lunch, transport and uniform: €1,500 to €3,500 per year combined
UN-affiliated families and diplomatic personnel often qualify for fee subsidies at VIS and AIS — confirm what is included in your assignment package before negotiating final terms.
Practical admissions tips
- Apply to two or three schools in parallel — VIS and AIS are competitive, while DISV and AMADEUS often have rolling capacity.
- For diplomatic and UN families, prioritise VIS first — the school maintains UN-affiliated quotas that simplify admission for treaty families.
- Bring apostilled school reports for the last two years and a vaccination record matching Austrian requirements.
- Visit at least two schools in person — the difference between a 1,400-pupil IB school and a 350-pupil boutique school is enormous in daily experience.
- Confirm whether your school of choice supports German-as-a-foreign-language from Year 1 if you plan to stay long term — bilingual ability matters for university and life integration in Austria.
