About Categorical Judging at the Science Fair

The Greater San Diego Science & Engineering Fair is an exciting and important San Diego community event that relies entirely on the generosity of our community's volunteers. The Fair will have about 800 science projects on display along with the 800 plus 7-12th graders who produced them.


How can you help? The Fair always needs more judges. Judging for the 2019 Fair will be Wednesday morning, March 13th  from 8:00 - 11:45 a.m. in the Balboa Park Activities Center. For those who register, a detailed judging day agenda and directions to the Center will be sent to you a week or two prior to the Fair.


Being a judge is actually a lot more fun than it sounds. It mostly requires listening to enthusiastic young kids tell you what they did.


For anyone new to judging, there is a great deal of advice regarding "how to judge" and "what kinds of questions to ask" (see links below). Also, judging is done in teams, so there are typically experienced judges to assist someone new, should that need arise.


Most of the projects are done by 7th and 8th graders, so you don’t need to be a PhD (although we do appreciate having PhD’s on our judging teams).  You do need a background in science, math, computers or engineering and a good knowledge of the scientific method.


Online Morning Judging Registration for the 2019 Fair is now closed.  Thank you for your interest.  

If you are still willing and able to be a Behavioral Science or Consumer Science judge for the 2019 Fair, please come to the Balboa Park Activity Center between 7:15-7:45 am, Wednesday, March 13, 2019.  We will do “on site” registration.
