USNCO Coaching

Coaching sessions will be organized over Zoom and coordinated by the American Chemical Society. 30 minute tutorials will be followed by 1 hour and 30 minutes of small group work in breakout rooms. Up to 40 coaches will be available for up to 200 students, coaches will work in teams of two, and each team will work with approximately 11 high school students at a time. Coaching teams will be the same throughout the season. Students can apply to participate in this program until Monday, December 6. Please encourage interested students to apply here:

USNCO Recruitment Grants

Applications are due by November 15, 2021.

USNCO Teacher Training Workgroup

The content covered in USNCO exams is typically more involved than a standard high school chemistry curriculum. This serves as a barrier to entry for schools not already involved in the USNCO. In addition to coaching programs to help students improve individual performance, we believe a teacher training course would equip more schools to confidently participate and sustain participation over time.

The training course will cover content divided into the ten topics covered in USNCO exams. Each topic will be covered at the local section exam and national exam levels. The course will be available as a free resource and will be hosted at the ACS Learning Center platform.  

We are seeking chemistry educators who are willing to be a part of the working group to prepare and produce the training course. Those with various professional backgrounds and experience with the USNCO are invited to apply. Experience with the USNCO is not a prerequisite for selection.

The USNCO Subgroup of SOCED will be overseeing the work and advising when necessary. ACS USNCO staff will cover the logistics and technical aspects of the course production.

Products produced during this project will be the property of the ACS. Up to 30 contributors will be compensated for their work with a $500 honorarium and will be asked to sign a contract. 


  • Oct 2021: Application open for contributors to USNCO Teacher Training Course
  • Nov 2021: Applications close, reviewed by USNCO subgroup of SOCED
  • Dec 2021: Virtual kick-off meeting held
  • Jan 2022 – July 2022: asynchronous work on content by contributors, course built in ACS Learning Center by staff
  • Oct 2022: Target launch date

Applications are due by November 15, 2021.
