In order to have a successful fair, we need judges to review the students’ project boards and conduct student-scientist interviews. Click on the button to find out more about becoming a science fair judge.
Up to 350 projects are eligible to compete, and each will receive careful consideration by volunteer judges. These volunteers work extended hours to ensure our communityโs promising young scientists and engineers receive timely feedback through the Awards Results. Judges, made up largely of veteran Science Fair volunteers, are well aware of how hard our students work over several months in preparation for each yearโs competition. They are proud to contribute their time under extraordinary circumstances to make student feedback possible.
The results of the 2025 Science Fair can be found below.
CCCSEF would like to thank the sponsors of the 2025 Science Fair, and the companies who provided judges that allowed the fair to take place for our communityโs youth. They are shown below:
