involvement.
Are you a Yale student or eager Science Olympiad alumni that wants to help organize or run events at our invitational? We have several way for you to get involved in our 2026 tournament.
Board | This is a very selective and high commitment role available for Yale undergraduate students only. The members of the YUSO board will engage in weekly meetings with specialized roles in preparation for the invitational.
If you are a Yale undergraduate student who would like to apply, please watch out for next year's application around fall 2026.
Event Supervisor | The Event Supervisors will be responsible for writing exams and running the event during the day of the tournament, whereas the exam review committee will check over exams to ensure sufficient test quality. Thus, both positions require significant Science Olympiad experience.
General Volunteer/Assistant Event Supervisor | The General Volunteer and Assistant ES positions require the lowest degree of commitment. These people will be responsible for helping out with various tasks on the day of the invitational. Assistant Event Supervisors will shadow the Event Supervisors, and may have to run the event if the Event Supervisor is not available on the day of the competition.
