Frequently asked questions

The IEO is an annual competition for high-school students worldwide in economics and finance. It rewards applied reasoning across three rounds and is supported by Nobel laureate Eric Maskin. Participation in the official competition is free.

High-school students who are under 20 on 30 June of the competition year. Teams have up to five contestants, with one or two team leaders. No prior olympiad experience is required.

A Finance & Economics multiple-choice test (40 questions); an open-questions round (five questions, of which four are graded); and a team business case presented in English before a panel of judges.

The competition is scored out of 200: the individual Economics and Finance part (150) and the team Business Case (50). Raw marks in each part are standardised with z-scores and then combined, so the parts weigh together fairly; ties are broken on the Economics and Finance result.

Gold, silver and bronze go to the best overall individual results, decided by the International Board. The total number of medals is capped at half of the invited contestants (counted as participating countries times five), so fewer than half of finalists take a medal. In 2025 (Baku), 133 medals were awarded: 24 gold, 43 silver and 66 bronze.

Participation in the official Olympiad is free of charge. Any regional arrangements are confirmed by each region. Guidance from this site is a separate, optional service.

Enter your regional round, then top performers are selected to represent their region at the international finals, held in a different host city each year (Baku in 2025).

IEO 2026 took place in Shenzhen, China, on 12–20 July 2026. This is a completed edition; confirm the international organiser’s 2027 notice for the next final.

The IEOC 2027 handbook lists an online Preliminary Round in December 2026, an Annual Summit in East China in spring 2027, and international opportunities in summer 2027. Exact dates, current entry deadlines and fees require the latest organiser notice. The IEOC 2027 handbook lists Junior-SL for G9 and below, entering individually or in teams of 3–5; Junior-HL and Senior for G9–G12, in teams of 3–5. Junior groups use Chinese and English; Senior uses English.

OpenTrack is a separate online category with its own registration and scoring. The listed 2026 competition window, 13–19 July, and 9 July registration deadline have passed. Confirm the next season’s dates, eligibility and fee terms with the international organiser.

We cover Greater China: Chinese Mainland, Hong Kong, Macau and Chinese Taipei. See the Regions page, then contact us for the round that applies to you and its current schedule.

Start from the official syllabus, build core micro, macro and finance, then practise past open questions under time and rehearse the case as a team. The Resources page has a five-phase plan, and a mentor can tailor it to your level.

A strong IEO result is an internationally benchmarked, externally verified credential in economics, PPE and finance – scarce by design, since the medal cap means fewer than half of finalists earn one. Beyond the certificate it signals genuine analytical, quantitative and teamwork ability, as one part of a whole application.
