USA Chemistry Olympiad (USNCO)

USA Chemistry Olympiad (USNCO) is the premier high school chemistry competition in the United States. It is organized by the American Chemical Society (ACS) and serves as the primary selection pathway for the U.S. team that competes in the International Chemistry Olympiad (IChO).

History and Significance
The USNCO identifies and trains the most talented high school chemistry students across the United States. The competition begins with a national multiple-choice exam (Local Section Exam), followed by a more advanced National Exam for top scorers. The highest-performing students are invited to intensive study camps, where the final U.S. International Chemistry Olympiad team is selected. The exam covers analytical, organic, inorganic, and physical chemistry, requiring both conceptual understanding and problem-solving ability.
