A team of secondary school students representing Ireland at the International Mathematical Olympiad (IMO) in Rio de Janeiro has obtained the highest score ever achieved by an Irish team in the history of Irish participation in IMO. Two of the team members, Cillian Doherty (from Colaiste Eoin, Booterstown, Co. Dublin) and Anna Mustata (from Bishopstown Community School, Cork) won bronze medals at the contest, which is the first time ever that Ireland has won two medals at an IMO. All four of the other team members were awarded Honourable Mentions at the contest. These were: Antonia Huang, Mount Anville Secondary School, Dublin; Mark Heavey, Blackrock College, Dublin; Mark Fortune, CBS Thurles Secondary School, Tipperary; and Darragh Glynn, St. Paul's College, Raheny, Dublin.

The International Mathematical Olympiad (IMO) is the World Championship Mathematics Competition for High School students and is held annually in a different country. The first IMO was held in 1959 in Romania, with 7 countries participating. It has gradually expanded to over 100 countries from 5 continents.

UCD are  involved in training students for the International Mathematical Olympiad thorough Mathematics Enrichment Classes, which are offered annually to hundreds of secondary school students and organised by Dr Marius Ghergu.
