International School of Budapest

What International School of Budapest does

International School of Budapest (ISB) is a private K-12 international and bilingual school located at 1117 Budapest, Budafoki út 97-103 in District 11, Hungary, serving approximately 380 students from Preparatory year through Grade 12. The school operates two academic programs: an International Academic Program following the Cambridge International curriculum delivered in English by native English-speaking teachers, and a Bilingual Academic Program combining the Cambridge International curriculum with the Hungarian National Curriculum framework for bilingual schools, allowing graduates to receive both internationally accredited Cambridge certificates and state-recognized Hungarian diplomas. The pathway culminates in the IB Diploma Programme for Grades 11-12, delivered under ISB's IB World School authorization.

ISB's underlying platform combines the Cambridge International and Hungarian National curricula with a Microsoft-based digital learning environment, the ISAMS school management system for parent communication, and the E-Kréta Hungarian national education platform. A fee-paying English as an Additional Language (EAL) program supports non-fluent English speakers from Grade 2 through Pre-IB, and an After School Activities program offers robotics, sports, arts, and language clubs in partnership with external providers including FunSide School and Túskeúszás. Class sizes are kept at 14-18 students with a 5:1 student-to-teacher ratio, and the average staff tenure is 6 years with several teachers exceeding 10 years.

The business model is direct-to-consumer tuition-based, with revenue derived primarily from recurring annual tuition contributions across both academic programs, supplemented by EAL fees and Assessment/Trial Day fees. Admissions are conducted via Open Day campus visits and mandatory assessment days evaluating English, mathematics, and (for bilingual applicants) Hungarian proficiency, with year-round rolling enrollment subject to seat availability. Geographic reach is extended across greater Budapest through a door-to-door school bus partnership with Capital Bus, and the institution holds Hungarian OM identifier 035019 as a state-recognized bilingual school. Key outcomes cited include an 89% IGCSE exam success rate with over 50% of grades at 7 or higher, and English test scores for Grades 6 and 8 running 150-200 points above Hungarian national averages.
