The International Chemistry Olympiad (IChO) is an annual international competition for talented young students in secondary schools and colleges. The first IChO took place in Prague in 1968. Since 1987, Switzerland has sent delegations to more than 30 IChOs but has never been a host country itself. The time has come in 2023! The Swiss Chemistry Olympiad Association (SwissChO) and ETH Zurich have been awarded the contract to host the event in Switzerland.
