American International School of Zagreb

💙☀️ And just like that, another incredible year at AISZ comes to a close.

Our Lower School and Upper School assemblies were filled with everything that makes our community so special - laughter, reflection, celebration, and heartfelt goodbyes. Friends signed yearbooks, shared memories, and wished each other well as they headed off for summer adventures. There were smiles, there were tears, and there were many reminders of the strong connections that make AISZ feel like home.

For some members of our community, this was a final farewell. While it is never easy to say goodbye, we are grateful for the impact they have had on our school and wish them every success on the next chapter of their journey. They will always be a part of the AISZ family.

To all of our students, families, faculty, and staff: thank you for your hard work, dedication, kindness, and spirit throughout the year. Together, you have made this a year full of growth, achievement, and unforgettable memories.

We wish everyone a safe, relaxing, and well-deserved summer break. Enjoy every moment, make wonderful memories, and return refreshed for new adventures ahead.

We can’t wait to welcome our Bears back in August and continue our learning journey together. 🐻✨

Happy Summer, AISZ! 💙

🐻☀️ Lower School Fun Day brought out the biggest smiles, the loudest cheers, and plenty of Bear spirit as students jumped into a day full of games, challenges, and friendly competition.

From teamwork to determination (and a whole lot of laughter!), our Bears gave it their all and created memories to last all summer long. It was the perfect way to celebrate an incredible school year and kick off the holiday season in true AISZ style!

🎸🎤 What a way to kick off the last days of school! The AISZ Upper School Band brought the energy, the crowd brought the volume, and together they turned the morning into an unforgettable celebration. ⚡️🎶

A huge shoutout to our talented student musicians for giving us the perfect soundtrack to close out an amazing school year. ☀️🎵

The Grade 9 Poetry Slam left us absolutely speechless. 🎤✨

Standing behind a microphone and sharing your own words in front of an audience takes incredible courage—especially at fifteen. Yet our students stepped up with confidence, authenticity, and heart, completely owning the stage.

One moment, they had the audience laughing with clever wordplay and sharp wit. The next, the room fell silent as they shared powerful personal stories that demanded every ounce of attention. Through poetry, they showed vulnerability, creativity, and the courage to be unapologetically themselves.

Thank you, Grade 9s, for reminding us of the power of storytelling and the importance of finding—and sharing—your voice. 🐻💙

Our Grade 11 students rose to the challenge and delivered an outstanding Group 4 Project! 💧🌍

Working under the theme “Solutions for a Thirsty Planet” students spent 10 intensive hours combining fieldwork, scientific investigation, collaboration, and data analysis to explore one of the world’s most pressing issues: water depletion.

The depth of their research, critical thinking, and problem-solving was truly impressive. By applying interdisciplinary science to real-world challenges, they demonstrated not only academic excellence but also a commitment to creating a more sustainable future.

Well done, Grade 11s-we are incredibly proud of your dedication, curiosity, and innovation! 👏✨

A huge milestone for our Grade 8 students! 🎓✨

The Moving Up Ceremony was a beautiful and poignant celebration of their Middle School journey - a moment to reflect on the memories, friendships, growth, and achievements that have shaped them along the way.

As they officially transition into High School, we are excited to see them embrace new opportunities, challenges, and successes. Congratulations, Grade 8s!

We are so proud of all you have accomplished and can’t wait to see what the future holds.💙

Project Week in the Upper School came to life through our Middle School EPCOT Showcase! 🌍✨

Our students transformed their learning spaces into vibrant cultural exhibitions, representing countries from around the world through food, traditions, games, nature, and stories. Through in-depth research, they explored the essence of each culture and uncovered local stories that highlighted moments of national pride and identity.

AISZ community traveled from booth to booth collecting passport stamps, while our young presenters confidently shared their knowledge, designed interactive experiences, and even pitched grant proposals to support their ideas.

A celebration of curiosity, creativity, global-mindedness, and student voice - well done to all who made this incredible showcase possible! 🌎💫

A special mention to team USA for their exceptional booth building skills and for making the USA booth so grand ahead of the 250th celebration. 🇺🇸

A memorable celebration for our Grade 5 student Bears as they marked the end of their Lower School journey at AISZ! 🎓✨

The ceremony began with heartfelt speeches of gratitude from the students, followed by an energetic group dance that filled the entire room with excitement and had the audience cheering along.
A special thank you to their exceptional teacher, Mrs. Melarvie, for guiding and inspiring this class throughout the year.

Our Lower School Principal, Mrs. Doreen Garrigan, then officially handed the class over to Upper School Principal, Dr. Katherine McMullen, symbolizing the exciting transition ahead.

The ceremony concluded with students proudly receiving their certificates and officially completing Grade 5.

Congratulations to the Class of 2026! We wish you every success in the next chapter of your journey—and we’ll see you upstairs! 💙

What a phenomenal performance by the Grade 6 students at AISZ in The 3 Cows! Performed to a packed Blackbox audience, the production captivated everyone from start to finish. The gripping storyline, nail-biting action, stunning lighting, and perfectly timed music kept the audience on the edge of their seats throughout.

A huge congratulations to the talented cast for bringing the story to life with such energy and confidence. Special thanks also to the AISZ Performing Arts, Set Design, Music, and Stage Production teams whose creativity, dedication, and hard work made this fantastic show possible. It was truly an unforgettable theatrical experience!
