The International Olympiad "Tuymaada" is an annual summer science competition held in Yakutsk, Republic of Sakha (Yakutia), Russia. It brings together talented secondary school students from Russia and many other countries to compete in theoretical and problem‑solving contests in mathematics, physics, informatics (computer science), and chemistry. The event typically runs for about a week and includes opening and closing ceremonies, team excursions, and cultural exchange activities. Participation is generally aimed at academically advanced high school students who are members of national, regional, or specialized school teams selected by their home institutions or education authorities. While the primary focus is on rigorous written and/or computer‑based exams modeled on national and international olympiad standards, students also benefit from exposure to peers from other regions and countries, practice under competition conditions, and opportunities to interact with university faculty and researchers involved in the Olympiad’s jury and organizing committees.
