The Chemistry Olympiad is a multi-tiered competition designed to stimulate and promote achievement in high school chemistry. The local and U.S. National Chemistry Olympiad competitions are sponsored by the American Chemical Society. Each year, four students are chosen to represent the U.S. team at the International Chemistry Olympiad competition, which is hosted by a different country each year.


Goals of the U.S. National Chemistry Olympiad are set by a subcommittee of the Society Committee on Education. The Chemistry Olympiad program aims to:

  • Stimulate all young people to achieve excellence in chemistry
  • Recognize outstanding chemistry students and, in doing so, encourage additional learning at a formative time in their intellectual development
  • Recognize the excellent achievement of teachers and the importance of the school environment
  • Provide contact between ACS local sections and area schools, and foster interest among professional chemists in teaching chemistry
  • Challenge the chemical knowledge and skills of young students in an international arena
  • Foster cross-cultural experiences and acquaint students with similarities and differences between themselves and their counterparts from other nations


Since 1984, the ACS Donald F. and Mildred Topp Othmer Chemistry Olympiad Endowment has been the primary sponsor of the U.S. Chemistry Olympiad, with additional support from the:
