U.S. National Chemistry Olympiad Competition
Approximately 1,000 students sit for the 3-part national exam. No more than two students from any given school can compete in the national competition. The 20 top-scoring students are chosen to attend a study camp where they will try to win a spot on the U.S. team.
The three-part, 4.5-hour exam consists of the following (may be administered in any order):
|Part I||Part II||Part III|
ACS calculates the average number of correctly answered questions by topic area. Scores are ranked as follows:
- outstanding performance
- above average
- below average
Students will only receive the performance ranking on Part I (multiple choice) of the exam. ACS does not distribute individual scores.
