The **International Conference of Young Scientists (ICYS)** is an annual forum where secondary school students from around the world present their original research in physics, mathematics, computer science, environmental science, and related fields. Participants prepare and deliver conference-style presentations in English and defend their work during discussions with an international jury and peers. Students are typically selected and sent by their country’s national organization or a designated school/academy, often after success in local or national research competitions. The conference emphasizes both scientific quality and communication skills, offering an authentic taste of academic conferences, exposure to international standards of research, and cultural exchange with participants from many countries. Awards are given for outstanding presentations and posters, but the main benefits include feedback from experts, networking with like‑minded students, and experience in formally presenting research on a global stage.
