International Baccalaureate

AISZ is an authorised IB World School and proud to offer the International Baccalaureate Diploma Programme — one of the most respected pre-university qualifications in the world. Recognised by leading universities across the United States, the United Kingdom, Europe, and beyond, the IB Diploma prepares students not just for academic success, but for a life of inquiry, integrity, and international understanding.

The full IB Diploma is open to all AISZ students in Grades 11 and 12. Students choose six subjects across the IB's six subject groups, selecting three at Standard Level and three at Higher Level. In addition to their subject courses, all IB Diploma students complete Theory of Knowledge, write an Extended Essay, and fulfil their Creativity, Activity, and Service commitments — developing the breadth of mind and depth of character that make AISZ graduates stand out.

AISZ also works with Pamoja, the only IB-certified online course provider, to extend access to subjects not offered on campus.

A note for Croatian university applicants: IB Diploma students whose mother tongue is Croatian and who are planning to enrol at a Croatian public university do not need to sit the national matura examination, provided they take IB DP Croatian Literature, Mathematics, and English.
