The IBO competition consists of practical and theoretical tests. The host country of the IBO event provides the raw scores of participating students to the international Jury.
After approval of the student’s raw scores by the Country Coordinators, the host country calculates the final ranking based on the T-scores for the practical and theoretical tests (50% + 50%).
The final ranking determines the number of gold, silver, and bronze medals, as well as certificates of merit in accordance with the IBO Operational Guidelines.
