Syllabus

Essential Information about the parts of the competition and the rating system.
This version of the Syllabus was approved by the International Board on 28/12/2024.
General
1.1. National education systems and curricula vary in terms of structure and content, but the tasks of the IEO are composed in a way that facilitates equal competition. The tasks are not aimed primarily at testing the knowledge of theory. A significant share of the tasks is practical-oriented, test analytical skills and curiosity. The IEO tasks are created considering that its contestants are predominantly students of (senior) high school, or level 3 according to UNESCO International Standard Classification of Education (ISCED 2011). Yet, provided that the IEO is a worldwide selective competition for national teams, some tasks on the topics that are outside the scope of a traditional high school curriculum may appear.

1.2. Economics and Finance (Financial Literacy) parts of the competition are individual. The competition in Business Case is a team competition.

1.3. The maximum individual final points for the parts of the competition (variable M) are the following: 100 for Economics part, 50 for Finance (Financial Literacy) part, 50 for Business Case part. The individual points for the Business Case part equal the team points for the part.

1.4. In every part of the competition, the result is first computed in raw points. Raw points are then normalized to get the final points according to the following procedure.

Let Gi be the raw score of the contestant (or team in the Business Case part) i in the part of the Olympiad, A β€” the average of all raw scores, Οƒ β€” standard deviation of all raw scores. Then we define Z-score of the contestant i as:

Zi =(Gi βˆ’ A)/ Οƒ

The final result of the contestant i is then calculated as follows:

Fi = M/2 Γ— {min{max{1 + zi/2; 0}; 2}

Where M is the maximum possible result of this part (in final points) specified in this Syllabus.

If some scores change in the process of moderation, Z-scores and final scores are recalculated.

1.5. The total individual results are calculated as a sum of all three final scores. Ties are broken by taking the score from the Economics part. If still tied, the Finance (Financial Literacy) part results are taken.

1.6. The total team results are calculated as a sum of:
  • The average final score of team members in the Economics part divided by 2;
  • The average final score of team members in the Finance (Financial Literacy) part;
  • The team score in the Business Case part.
Ties are broken by taking the average team score from the Economics part. If still tied, the Business Case part results are taken.
