Introuduction

The International STEM Olympiad (ISO), originating in Germany in 2012 with 13 years of history, has expanded into 153 countries and gained worldwide popularity. Designed for students in Grades 1-12, the ISO sparks curiosity through picture-based questions for younger grades; while it presents complex, interdisciplinary challenges integrating mathematics, physics, chemistry, and biology, simulating real-world research scenarios for older students. In ISO, science transforms from textbook terms into an exciting adventure shared with tens of thousands of peers globally.
In 2025, ASEEDER partnered with the ISO organizing committee to introduce this challenge to China, providing Chinese students with a platform to compete and exchange ideas with STEM enthusiasts worldwide, laying a solid foundation for future applications to top global universities, pursuing STEM careers, and embarking on academic journeys. Top performers in the Final Round will be invited to attend the Grand Final in Rome, Italy. This not only adds an internationally recognized highlight to their academic profile but also helps them cultivate a global perspective, ignite a lasting passion for scientific inquiry, and truly embody the core values of quality education and lifelong learning through interaction with outstanding students from around the world.

Grand Final Exam
All finalists are divided into three categories (Grades 3-5, 6-8, 9-11). They will answer 40 multiple-choice questions in English within a 75-minute time limit, testing their knowledge and critical thinking. Awards are allocated separately by grade. The ISO brings together elite students worldwide to unlock their potential and push their boundaries in scientific exploration. The event is not merely an ultimate test of their academic depth, but also a precious opportunity to broaden their global perspective and sharpen their scientific thinking.2
DIY Challenge
The DIY Challenge inspires young minds’ innovation and engineering potential. Act as “young engineers”, they will embark on a journey of creation from 0 to 1. In this challenge, each team of two students had 3 hours to assemble a model from scratch using materials and instructions provided on-site. It’s a test of creativity, collaboration, and the thrill of turning ideas into reality.
