International Chemistry Olympiad

The International Chemistry Olympiad is an annual event in which countries from throughout the world send their four best high school chemistry students to compete against each other. About 80 countries participate in the competition, which is held in a different country each year.

The US National Chemistry Olympiad (USNCO) is a chemistry competition designed to stimulate young people to achieve excellence in chemistry. The American Chemical Society has sponsored the program since 1984. For more information, visit www.acs.org/olympiad.

The ACS Orange County Chemistry Olympiad is the first step in the US National Chemistry Olympiad. Typically, about forty High Schools from all over Orange County send up to four students each to compete in the Local Section exam, which is usually held in March. The top eleven or twelve scorers on this exam are eligible to advance to the national round of the competition where each student takes a five-hour exam that includes extensive laboratory work. Approximately 1,000 students across the US advance to this round. Those that score among the top twenty nationally on this test are invited to attend the Olympiad Study Camp. The top four at the Study Camp then go on to represent the US at the International Chemistry Olympiad in July. Over the past thirty-five years, six Orange County schools (Irvine, Sunny Hills, Troy, Beckman, University and Valencia) have had students qualify for the US National Chemistry Olympiad Study Camp.

2018 Results
For the local exam, 135 students from 39 different county high schools participated. The number was a bit lower than in the past due to an unforeseen conflict with the SAT test. The average score was 35.8 or 59.7%.

Eleven students from eight Orange County High Schools qualified for the National Chemistry Olympiad competition. Nationally, 1025 students reached this level. On Part I of the National Exam (the only portion of the test where the results are released) the national average was 30.8 or 51.3%. The eleven students from the Orange County Local section that competed had an average score of 42.5 or 70.8%. Once again, the students from our area excelled above those found in other Local Sections.

Four of the eleven finished with Honors (top 144 in the nation) while two others finished in the top twenty in the nation and will be attending the Study Camp at the Air Force Academy. Only one other section out of the 150 participating sections this year had more students attending the study camp than the Orange County Section. Congratulations to all the students and their teachers on this outstanding achievement.

2017 Results
This year 43 schools (a record) with a total of 155 students (another record) competed in the Orange County Section Chemistry Olympiad exam. Twelve students (we had one automatic qualifier) from seven Orange County High Schools qualified for the National Chemistry Olympiad competition, of which four finished with High Honors (top 50 in the nation). Only one other Local Section (Indiana) out of the 144 competing Local Sections in the U.S. had more. The students and their teachers from the county are to be commended for this exceptional achievement.

2016 Results
This year 39 schools with a total of 141 students competed in the Orange County Section Chemistry Olympiad exam. 13 students (we had one automatic qualifier) from 9 High Schools from Orange County qualified for the National Chemistry Olympiad competition, of which 4 finished with High Honors (top 50 in the nation). Only one other Section in the US had more, and only 4 Sections also had 4 High Honor students like us. This is commendable for a smaller section like ours, especially when one considers the fact that there were 144 participating Local Sections.
