Chemistry Olympiad

The Southern New Mexico-West Texas Chemical Olympiad Competition serves as the American Chemical Society Rio Grande Section local exam used in qualification for the U.S. National Chemical Olympiad (USNCO) competition. Full details of the USNCO exam are available at the ACS website link below. A maximum of 10 students from the ACS Rio Grande Section, comprising portions of Southern New Mexico and West Texas, will be selected to participate in the USNCO.


USNCO Eligibility Requirements:

Note: Participation in the Southern New Mexico-West Texas Competition on March 16, 2019 is open to all interested students regardless of citizenship or other qualification criteria for the national exam.  The following are requirements to participate in the national exam to be held on April 27 (complete eligibility rules are given under the Eligibility Information link on the competition web page):

  • The student must be a U.S. Citizen or permanent resident (green card holder) on the day the national exam is administered.
  • The student must be a regularly enrolled high school student who will graduate no earlier than the spring of 2019.
  • Students must be younger than 20 years old as of July 1, 2019.
  • A total of no more than two qualifiers are allowed from any single teacher or any single high school in the local section.

Selection of USNCO Qualifiers: Eligible students will be selected to participate in the USNCO exam based on their written examination scores in the local competition held on March 16. Students must participate in the USNCO Division of the local competition in order to qualify. In the case of a tie, selection will be based on performance on the individual experiment. Alternates will also be identified in the case qualifying students decline to participate or are later determined to be ineligible.
