The competition for the U.S. team was fierce, beginning with a multiple-choice exam taken by nearly 16,000 high school students across the country. The top 1,000 then advanced to take the National Chemistry Olympiad test. From there, the top 20 went on to a study camp at the University of Maryland, College Park, where four were selected for the team along with two alternates.  

ACS has sponsored the American team annually since the U.S. joined the Olympiad in 1984. Principal funding is through the ACS Donald F. and Mildred Topp Othmer Olympiad Endowment, with additional support from The Chemours Company; the University of Maryland at College Park, department of chemistry and biochemistry; Carolina Biological Supply Company; Macmillan Learning; Texas Instruments; Pearson; and Fisher Science Education. 

The International Chemistry Olympiad originated with Czechoslovakia, Poland and Hungary in 1968. Soon, other Eastern European countries joined the event; Western Europe began participating in 1974. The first U.S. team competed in 1984, winning one silver and two bronze medals.
