Q: What is the IEO (International Economics Olympiad)?
A: The IEO (International Economics Olympiad) is an annual international competition covering Economics, Financial Literacy, and a team Business Case for upper-secondary students. Each country sends up to 5 contestants. Students don't register directly - participation is through a national qualifier. See ieo-official.org for current rules and host details.
TL;DR
The International Economics Olympiad (IEO) is an annual competition in economics, financial literacy, and a team business case for upper-secondary and pre-university students, selected and registered by each country’s national organiser.
Teams can include up to five contestants and one or two team leaders, with eligibility rules set in the official regulations (for example, age is measured relative to 30 June of the Olympiad year).
Medal thresholds and any special awards are set and announced by the jury after scripts are marked; always rely on the current year’s regulations and host communications.
Status: IEO official site + Articles of Association + Regulations of Competition + 2024/2025 host-year sites checked 2026-01-26 - structure and eligibility rules are published and updated by IEO; host locations, schedules, and year-specific formats must be confirmed on the current host-year site and annual regulations.
Keep the calculus and modelling muscle warm via our IP Maths tuition hub; those vector, optimisation, and regression drills line up perfectly with the IEO’s scoring rubric.
Registration quick answer (Singapore): Students don’t apply directly to IEO. Countries send national teams selected via a local competition; check the official IEO site for the current structure and contact links: https://ieo-official.org/
