The International Mathematical Olympiad (IMO) is the world’s most prestigious mathematics competition for school students, with 110 countries competing in 2025. Ireland first took part in 1988, and this year’s return to Australia proved to be a landmark moment for the Irish team.
Our six contestants delivered Ireland’s best-ever results in 38 years of participation:
-
Tianci Yan (Wesley College, Dublin) – Silver Medal
-
Owen Barron (Coláiste an Spioraid Naoimh, Cork) – Silver Medal
-
Vitalii Halushko (St Vincent’s College, Castleknock) – Bronze Medal
-
Angyang Li (Institute of Education, Dublin) – Honourable Mention
-
Jack McAuliffe (St Flannan’s College, Clare) – Honourable Mention
-
Ben Maguire (St Vincent’s College, Castleknock) – Honourable Mention
These results set several records for Ireland:
-
First time winning three medals (2 silver, 1 bronze).
-
Doubled Ireland’s total silver medal tally.
-
Highest ever team score, exceeding the previous record by 50%.
-
Ireland’s highest country ranking, breaking into the top half of the table for the first time.
-
Every team member received an award.
Behind these achievements lay months of dedicated preparation through the Irish Mathematical Olympiad (IrMO), enrichment programmes across six university centres, and intensive training camps in Ireland and Australia. The success reflects the commitment of students, teachers, the Irish Mathematical Trust, and the many supporters who make Olympiad training possible.
Ireland’s IMO journey in 2025 shows what can be achieved with collaboration, creativity, and perseverance.
Well done to all of your teachers, mentors and parents who have guided you on the path to become the great mathematicians that you are.
