2018-19 IrEUSO

Welcome to the competition site for IrEUSO 2018-19.

The 2018-19 IrEUSO is for students born on or after 1st January 2002. Letters & Registration Forms have been sent to the schools of qualifying students (based on their Junior Certificate Examinations results in Maths & Science). ONLY students who have received an invitation may participate. Substitutes or replacements are not acceptable. Only students in Transition Year (TY) or in Fifth (5th) Year may take part in the IrEUSO competition.

The Irish European Union Science Olympiad (IrEUSO) is an individual, subject based (biology, chemistry or physics) science competition for students who are sixteen years of age or younger on the December 31st prior to the competition. In order to prepare for the tests, students are encouraged to read around their chosen subject area. Students will be presented with material that they may not have met in school but they are required to use their scientific reasoning skills, problem-solving abilities and knowledge to solve the problems.

All participants at the IrEUSO receive a certificate. The top three students are awarded gold medals, the next three silver and the next six bronze. All medal winners will be invited to participate in Practical Training in February/March and after a further assessment, the top six (6) students will be selected to represent Ireland at the EUSO 2019 (4th – 11th May) in Almada, Portugal.
