Judges should have at least a bachelors degree and/or work experience in a scientific or engineering field. Judges will judge projects within their area of expertise, although it might be wider than you might think.
Judging takes place on a Sunday evening (optional) and a Monday morning.
The only restriction we have is that you not judge any division in which you have students who are related to you in some fashion. This means parents, teachers, and mentors. You may judge divisions in which you do not have such a relationship. For example, if you have a child who is participating in the Senior division but none in the Elementary division, then you could be a judge in the Elementary division.
