AISZ History
Founding of the School & Tuškanac Campus Opening
Established to serve the diplomatic and expatriate community, the American School of Zagreb (ASZ) opened with 13 students, laying the foundation for a lasting tradition of international education. Zagreb was the only non-capital city in Easter Block that opened an American school due to Yugoslavia’s (Tito´s) unique non-aligned status which enabled Western-style institutions to be present.

AISZ Community BBQ
We’re excited to bring the entire AISZ community together for our Community BBQ on Saturday, August 29 — a day to reconnect, meet new families, enjoy great food, and celebrate the start of another school year. Our Upper School families will begin the day with the Upper School Open House, offering parents an opportunity to meet educators, learn more about the academic year ahead, and get a closer look at what students can expect this year. From there, the celebration opens up across the whole school as Lower School and Upper School families come together for the Community BBQ. With food, refreshing drinks, games, activities, and plenty of time to catch up with friends old and new, it’s one of our favorite ways to begin the year as one AISZ community. This year’s gathering will also have an extra celebratory touch as we mark 250 years of the United States, making it an especially memorable occasion for our international community. We look forward to seeing our Bears and their families back on campus for an afternoon filled with connection, laughter, and school spirit. See you at the BBQ! 🐻💙

Welcome back Bears!
The halls of AISZ are buzzing again! Today, we officially welcomed our Bears back to campus for the first day of the new school year, filled with familiar faces, new friendships, and plenty of excitement for the year ahead. Our Upper School students kicked things off with their first assembly of the year, coming together as a community and welcoming many new students to AISZ. It was an especially memorable morning for our Grade 6 students, who made the big move from Lower School to Middle School and experienced their very first Upper School Assembly! Meanwhile, in Lower School, students were busy settling into their new routines, reconnecting with friends, meeting their teachers, and arranging their lockers for the year ahead. A particularly warm welcome goes to all of our new students and families joining the AISZ community this year. We are so happy to have you with us and look forward to seeing you become part of what makes our school such a special place. Here’s to new beginnings, new experiences, and an incredible year ahead. Welcome back, Bears! 🐻💙

Community Reviews
I went to this school for 4 years and I loved it. I think the whole concept was more about teaching us how to find information and adapt. It was a beautiful environment. If you have the opportunity to come here, I highly recommend it.
