Iuventa / Subpages / ICHO / International Jury


is the most important institution of the International Chemistry Olympiad (IChO). From the very beginning of the IChO there were many discussions about its functions and responsibilities. The basic structure of the International Jury was proposed already in the year 1993. Later the resposibilities of the International Jury were incorporated into the Regulations of the IChO as paragraphs 6 and 7.
