Competition Structure
Each delegation consists of either three or six students and upto three mentors/teachers (one of them is designated as the head of the delegation or "head mentor"). A delegation may also include a handful of guests and scientific observers. Students must be under the age of 15 by December 31st of the competition year.

The competition consists of three examinations, a multiple choice examination, a structured theoretical examination and a practical examination. All the examinations have durations of 4 hours (at the international olympiads), and are held on separate days. Each examination is evaluated independently from the other and the sum of the results of the examinations determines a participant's overall result. A scientific jury, which is installed by the host country, suggests the tasks.
