What is the International Research Olympiad (IRO)?

The International Research Olympiad (IRO) is a cross-disciplinary research-design competition for pre-university students. It tests the ability to formulate hypotheses, design experiments, analyse data, and communicate scientific findings through a three-stage format: Opens (online), Semifinals (proposal), and Finals (in-person).

Is the IRO useful for DSA applications?

IRO participation can be valuable for DSA portfolios, particularly for schools that prioritise STEM aptitude and independent research skills. Advancing to the Semifinals or Finals demonstrates research design ability beyond the standard curriculum. Verify your target school's DSA criteria for what evidence they accept.

When should I start preparing for the IRO?

Start 3–6 months before the Opens round. Focus on experimental design skills: formulating hypotheses, identifying variables, planning data collection, and understanding basic statistics. Work through the organiser's published sample questions to calibrate your preparation.

What topics are tested in the IRO?

The IRO is cross-disciplinary and does not test subject-specific content recall. Instead, it assesses research design, hypothesis formulation, experimental planning, data analysis and interpretation, and scientific communication. Strong foundations in any science subject - physics, chemistry, or biology - provide useful preparation.

How do I register for the IRO?

The 2026 cycle is closed. Check the official IRO site for the next cycle's registration details, eligibility requirements, and fees. Do not assume that the 2026 dates or thresholds will repeat. See internationalresearcholympiad.org for the next announcement. --- Last updated 25 August 2026 after the organiser marked the 2026 cycle complete. Review again when the next cycle opens.

Q: What does International Research Olympiad (IRO): IP Math & Physics Guide cover?
A: A parent-and-student primer on the IRO’s published format, eligibility, and where to confirm official details each cycle.

TL;DR
The International Research Olympiad is a research-design competition with three stages published on its official programme: an online preliminary (“Opens”), a proposal-style Semifinal, and an in-person Finals. Grade/age eligibility, fees, dates, advancement thresholds, and awards are set by the organisers each year-check the official pages for the current cycle before registering.

IRO tests research thinking, not memorised science facts: Check the current cycle rules before registering.
The path is usually online Opens, proposal-style Semifinals, then in-person Finals: Practise turning interests into testable questions.
A strong student can choose variables, controls, fair data collection, and a clear evidence claim: For example, replace "test fertiliser" with "compare plant height after 14 days using the same soil, light, water, and seed type".

Pair it with our IP Physics tuition hub so your uncertainty calculations and experimental write-ups stay aligned with what IRO examiners and SEAB practical rubrics expect.

Status: The official IRO site was checked on 25 August 2026. It says the 2026 cycle is complete and identifies the Finals as 19 to 21 June 2026 in Harvard Square, Cambridge, Massachusetts. The organiser directs readers to its Winners Hub and says dates for the next cycle will be announced on the site.

Do not use the 2026 registration sequence as if it were still open. Students preparing now should use the published practice materials while waiting for the next cycle's eligibility, fees, dates, and registration notice.

1 What exactly is IRO?

The International Research Olympiad is an international competition focused on designing and evaluating research investigations. It is cross-disciplinary by design; the organisers publish sample questions and programme notes on their site.
