International Chemistry Olympiad

The International Chemistry Olympiad (IChO) is a chemistry-themed International Olympiad. The first IChO was held in 1968. It has gradually expanded to over 80 countries from all continents. The competition takes place each year organized by a different host country observing the regulations and traditions of the IChO.

The IChO is intended to stimulate the activities of students interested in chemistry by a way of the independent and creative solution of chemical problems. It encourages cooperation and international understanding.^[1]
