Introuduction

The International STEM Olympiad (ISO), originating in Germany in 2012 with 14 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 Lisbon, Portugal. 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 scratch. 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.

Global Networking for Young Scientists
In 2027, the ISO in Lisbon offers more than just a science challenge. In this city, every tile bears witness to the glory of the Age of Discovery, and every corner hides the code of maritime civilization. Listen to the waves of the Great Navigation Era, from the watchtower of Belém Tower to the modern galleries on Avenida da Liberdade, from the Manueline dome of the Jerónimos Monastery to the cutting-edge tech labs along the Tagus River. This is not only a competition, but also a grand civilizational voyage. Contestants can not only showcase their intellect on the world's top academic stage, but also immerse themselves in Lisbon's timeless charm—exchanging ideas with global elites in ancient alleys and squares, feeling the perfect fusion of history, art, and science in this captivating city.
