The U.S. National Chemistry Olympiad (USNCO) program is a chemistry competition for high school students. The purpose of the competition is to stimulate young people to achieve excellence in chemistry. The American Chemical Society has sponsored the program since 1984. Local Chemistry Olympiad competitions are held each year in March. Top-scoring students are nominated for the National Competition.

We encourage all high school students in the ACS Joliet area (Will, Kankakee, Kendall, Grundy, and LaSalle Counties) to participate. For more information, contact us at

the 2020 olympiad has been cancelleD until further notice due to covid-19!

Please keep an eye out for more updates either here or on our social media channels.

The top-scoring student(s) from the local competition will be nominated to take the national exam in April. ​The date and location of the national exam is TBD. In order to participate in the National Exam, students must meet the eligibility requirements. Nominees will also be honored at our awards banquet in April.
