Logo for the American International School of Zagreb

The American International School of Zagreb (AISZ) is a private, coeducational, day school which offers an educational program from prekindergarten through grade 12 for students of all nationalities. The school was founded in 1966. The school year consists of two semesters, extending from August to June.

Organization: The school is governed by a seven-member school board. The U.S. Ambassador appoints the chairperson of the board and two additional members; there are two parent representatives, and two additional members are appointed by the board. The school director serves as an ex-officio member of the board. AISZ’s status is determined by a bilateral agreement between the U.S. government and the Croatian government on the status of the school.

Curriculum: The curriculum ranges from pre-kindergarten to 12th grade. Learning for the youngest students in pre-kindergarten is informed by the Reggio Emilia approach and follows New York State pre-kindergarten Standards. Grades K-10 are anchored in the American Education Reaches Out (AERO) standards using an inquiry framework. The International Baccalaureate Diploma Program (IB/DP) is offered in grades 11 and 12, and students consistently score above the world average. Students may choose the American high school diploma pathway that may include IB certificates for university admissions. The academic program is structured around power standards and a collaborative approach where students have choice and are trained to become experts in their own learning. AISZ’s student support program comprises a multi-tiered system of support in which teachers push-in to the classroom for interventions. Where identified, some students receive pull-out for targeted interventions and support. We serve a range of students with mild disabilities, and in limited cases students with intellectual disabilities. The school is also equipped with college and social-emotional counselors, as well as English as an Additional Language teachers. AISZ is committed to and accountable for advancing diversity, equity, and inclusion in all of its forms. As an international school, we embrace Diversity Equity and Inclusion (DEI).
