The U.S. National Chemistry Olympiad (USNCO) is a prestigious competition that recognizes and fosters exceptional talent in chemistry among high school students. This Olympiad is designed to challenge students, inspire their passion for chemistry, and prepare them for future careers in science.

History and Significance of the USNCO
The USNCO was established in 1984 as part of the International Chemistry Olympiad (IChO), a global competition that brings together the best chemistry students from over 80 countries. The USNCO serves as the qualifying exam for the U.S. team that competes in the IChO, which is held annually in a different country.
Structure of the USNCO
The USNCO is a two-stage competition. The first stage, known as the Local Exam, is a 60-minute multiple-choice exam that is administered at high schools across the United States in early April. The top 1,000 scorers on the Local Exam advance to the second stage, the National Exam.
The National Exam is a 12-hour written exam that is held at the Massachusetts Institute of Technology (MIT) in early June. The exam consists of nine multiple-choice questions and three free-response questions that cover a wide range of chemistry topics, including quantitative analysis, physical chemistry, organic chemistry, and biochemistry.
Benefits of Participating in the USNCO
Participation in the USNCO offers numerous benefits to students:
- Recognizes academic excellence: The USNCO is a prestigious competition that showcases the top chemistry students in the United States. Recognition from the IChO can lead to scholarships, research opportunities, and career advancements.
- Inspires passion for chemistry: The USNCO challenges students to think critically and solve complex chemistry problems. This can ignite a passion for chemistry and motivate students to pursue further education and research in the field.
