The Detroit Local Section Exam for the US National Chemistry Olympiad


Registration for the 2021 Olympiad is now open.  Click on the link below to register students.

The Chemistry Olympiad program in Southeast Michigan.
The United States National Chemistry Olympiad (USNCO) is a program for high school chemistry students. The USNCO is sponsored nationally by the American Chemical Society (ACS) and organized locally by the Detroit Section of the ACS.  Students from the nine-county area served by the Detroit Section are eligible to participate. 

The ultimate objective of the USNCO is the selection of the four members of the United States team for the International Chemistry Olympiad (IChO) to be held virtually this year.  
The selection process begins with the Local Section exam in March.  In southeast Michigan the top eleven students on the Local Section exam (after adjusting for the national rules) are named as Nominees of the Detroit Section.  The Nominees and nine Runners-up will receive cash prizes of $150 and $75 respectively. 
 Along with approximately one thousand students nationwide the Nominees will sit for the (virtual) National Exam in late April.  The top twenty on the National Exam will be invited to the Olympiad Study Camp at the Air Force Academy in Colorado Springs.  The four members of the US team are then chosen after ten intense and grueling days at the Study Camp.
