Information for Mentors

USNCO office is looking for college mentor for 2025-2027 term.  

USNCO program is seeking college chemistry teachers with background in one or more of the areas of organic, inorganic, analytical, physical, or biochemistry. Successful candidates should have laboratory and classroom experience with highly motivated students on or above the AP Chemistry level. Applicants must be prepared to make a three-year term commitment.  ACS pays an honorarium and most expenses associated with the study camp and the IChO.

Experience with the USNCO is not a prerequisite for selection.

If you are interested please submit an application and your current resume by January 5, 2024.

Applicants must arrange to send three letters of recommendation directly to Dr. Lily Raines, Manager, Office of Science Outreach, Education Division, at by January 19, 2024.  

Mentors play a vital role in preparing the nation’s brightest high school students to compete in the International Chemistry Olympiad. Each year, they guide the top 20 students from the U.S. National Chemistry Olympiad at a study camp through a series of preparatory problems to test student skills and ultimately select the Team USA for the International Chemistry Olympiad competition. Mentors accompany the Team USA to the IChO and serve on the International IChO Jury and translate and arbitrate the student’s exams. 

Inspire Talent! Become a Mentor in your Local Section

ACS Local Sections are also always looking for enthusiastic educators to help prepare the students to participate in the program locally. Please contact your Local Section coordinator if you are interested in volunteering.

ACS provides mentors with a handbook containing detailed guidelines on duties and responsibilities. Read an overview of responsibilities and a sample annual schedule below.

  • Mentor Duties and Responsibilities

    Mentors are high school teachers and college faculty who serve a 3-year term and receive an honorarium. ACS will provide mentors with a handbook containing detailed guidelines on duties and responsibilities. Most expenses associated with the study camp and the International Chemistry Olympiad are paid by ACS.

    Mentors might be required to attend two weekend meetings, one in the Spring to prepare the study camp, and another in late Summer during the ACS National Meeting to give a report on the study camp and IChO to the USNCO Subcommittee.

    Mentors accompany competitors of the International Chemistry Olympiad, where they also serve as a member of the International Jury.

  • Pre-Study Camp Meeting

    Mentors attend a pre-study camp meeting (late March, early April) to prepare for the June study camp, which includes the tasks:

    • Develop practice problems, study guides and lesson plans in advance of the June study camp
    • Determine fair testing material to prepare students for the international competition
    • Determine daily schedules, faculty staffing and additional curriculum requirements for the study camp
  • Study Camp

    The two-week Olympiad study camp is held early in June.

    Mentors arrive two days before the camp begins to test experiments, check procedures, write instructions, determine what solutions need to be made and what glassware must be procured.

    During the camp, mentors and students become a family unit. All participants live in the same dorm facility, eat all meals together, and share bathrooms and telephones. Mentors are also expected to monitor and motivate the students to behave maturely and to achieve their potential during the study camp experience.


Mentors use preparatory problems provided by the host country of the International Chemistry Olympiad to narrow the scope of the testing material. The preparatory problems typically contain as many as 50 theoretical and 10 laboratory problems covering physical, inorganic, organic, analytical, industrial, environmental, and biochemistry.

Mentors attend a pre-study camp meeting (late March, early April) to meet the faculty, determine curriculum, practice tests, and daily schedules for the two-week camp.

Mentors attend the two-week Olympiad Study Camp to coach and turor students and select Team USA at the conclusion of the camp.

Mentors accompany Team USA to the International Chemistry Olympiad competition.
