Contra Costa Science & Engineering Fair

Unsure if this competition is right for you? Read one student’s experience about participating in the Contra Costa County Science & Engineering Fair HERE.

The Contra Costa County Science & Engineering Fair is open to students who attend school in Contra Costa County. Students must be in the 7th-12th grades. No prior fair qualification is required (i.e., school science fair, etc.)

We do not accept students who attend school in other counties, states or countries. CCCSEF accepts mixed-county teams providing one member of the team attends school in Contra Costa County. However, all team members must reside and attend school in the greater Bay Area. No out-of-state students may be a member of a team.

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 250 projects are eligible to compete, and each will receive careful consideration by volunteer judges. These volunteers work extended hours to ensure our community’s 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 year’s competition. They are proud to contribute their time under extraordinary circumstances to make student feedback possible.

The results of the 2024 Science Fair can be found below.

CCCSEF would like to thank the sponsors of the 2024 Science Fair, and the companies who provided judges that allowed the fair to take place for our community’s youth. They are shown below:
