Thank you for your interest in becoming a judge for the OCSEF.

The Orange County Science & Engineering Fair (OCSEF) is an annual event organized to encourage the youth of our county in grades 6-12 to experience STEM by conducting a project and to consider a career in science, math, computer science, or engineering. Judges play a critical role in the student’s science fair experience. Your judging can affect students profoundly, sometimes altering their career choices and almost always influencing their attitudes toward science and technology.

The 2024 OCSEF Board Award Judging Program will be conducted virtually on Wednesday, March 6, 2024. 

Judges evaluate projects and interview students to determine which projects merit receiving awards in their category. Each year several hundred students present projects at the OCSEF and judging is the culmination of their hard work. As a judge, you become an important part of their learning, and your encouragement has an impact on their view of science, technology, math, and engineering (STEM).

The student interviews are the highlight of the OCSEF. It is an opportunity for students to showcase their work to the judges and for the judges to create a positive and welcoming experience for the students. Our goal is to make the OCSEF a memorable experience for the 6th – 12th grade students who participate and, hopefully, provide a spark to pursue more education and careers in one of the STEM fields.

OCSEF Judging Programs

Board Award Judging Program Organization

Judges work in a team with others. First-time Judges will team with more experienced Judges. Each Judge individually evaluates projects in their category and participates as part of a team in student interviews. Judges convene as a team to deliberate and decide which projects merit receiving awards in their category.

Each team is led by a Judging Captain who coordinates the activities of the Judges assigned to their category. This includes assigning judges to teams, reviewing the judging objectives and policies for evaluating projects, leading the deliberations on awards at the end of the day and reporting the awards results to the Director of Judging.

Judging the Virtual Fair – Timeline and Responsibilities

The 2024 OCSEF will be conducted virtually. Students will upload a slide deck describing the key elements of their projects to the OCSEF Survey Monkey platform. Judges will review no more than 12 projects in their category online, at their convenience, before the student interviews. The judging team will conduct student interviews.

Past OCSEF judges say

“Thank you very much for allowing me to participate in this event as a judge. I had a great time reading the abstracts and was thrilled to see the projects as well as speak to the students. I would definitely be interested in joining you next year so do keep me in mind.”

“I thank you for a wonderful day! I had a great time meeting and working with all of my fellow judges.”

“I am greatly encouraged to see such enthusiasm for science and engineering with these youngsters. They are our future, the best and the brightest. I will indeed be a part of the next cycle as a judge.”

It may be selfish, but we tend to feel great when we help others. Perhaps it’s the joy we see on their faces when we’ve accomplished a huge task for them, or the fact that we also gain a lot out of these experiences in terms of friends, contacts, and experience. Either way, volunteering is a rewarding experience which benefits ourselves and organizations alike.
