The International School of Budapest International Bilingual Primary and Secondary School is the largest English-Hungarian bilingual international school in Hungary. We provide an international education in a caring environment to children from 5 to 18 years old, covering preparatory, primary and secondary school education. ISB is a unique school in Budapest, as it provides both an accredited Cambridge school report and a state-accredited Hungarian report at the same time.
ISB is a registered Cambridge International School, an IB World School and a registered Hungarian private school.
The international accreditation of ISB was given by Cambridge International Examinations, a major international accrediting organisation based in the UK. The organisation provides a curriculum and qualifications recognised worldwide for international schools. There are more than 10,000 Cambridge schools in over 160 countries.
The ISB has also been awarded Cognia accreditation in 2024. This accreditation, conferred by the Cognia Global Accreditation Commission, provides a nationally recognised mark of quality for our school. As a result, our institution is part of the Cognia global network of over 36,000 schools in 90 countries.
ISB is an IB World School and we have been offering the IB Diploma Programme to suitable high school students since September 2020.
ISB has a Hungarian accreditation from the Hungarian Educational Ministry as Hungarian-English Bilingual Primary and Secondary School (Ministry ID: 035019). Thus ISB is authorised to issue an official Hungarian school report in accordance with the Curriculum for Bilingual Schools of the Hungarian National Curriculum. This is accepted in all state schools in Hungary.
