PUSO is hosting Princeton's tenth invitational tournament on February 7th, 2026!
Over 800 of the nation's high school STEM students will be competing, and we need volunteers to assist with everything from grading tests, scoring building devices, handing out trophies/medals and directing confused high school students across campus, etc. If you can't help the entire day, volunteer for at least 1 shift and get free boba, lunch, or breakfast! Check us out at https://scioly.princeton.edu 😄

Hi everyone!
As we draw closer to the tournament, we are sending out an update on the 2022 PUSO Invitational. We are moving to a Mini SO format with optional build events in order to allow more students to participate.
Essential information is bold in the document linked below. As always, if you have any questions, please reach out to us. We thank you for your patience and we look forward to hosting you all virtually!

Tournament Format The 2022 PUSO Invitational will be moving to a Mini SO format.

Hi everyone,

Due to recent University guidelines and the development of the Omicron variant, the Princeton University Science Olympiad tournament will be held virtually rather than in-person as we had previously planned.
We are very disheartened by the news, but our priority is the health and safety of everyone and this development is what appeared to be a necessary adjustment.

As a result, we will be expanding the number of teams and reopening registration. If you would like to compete in the virtual tournament, you can register at this link: https://docs.google.com/forms/d/e/1FAIpQLSc7XHm-AW1e2cOOAy9Zb7tMqg2gN_5g_MQE4yLlVjPu3iIdZQ/viewform?fbclid=IwAR3RwFvJHYvYAgTSxb6XZE2lmXSPLabo_oJNgblUioWgFPxFRhcDHfvCziA
More details regarding the switch to the virtual format will be released shortly.

Please let us know if you have any questions or concerns.

Have a happy and healthy holiday season.
