About the Fair

The Connecticut Science & Engineering Fair is a yearly, statewide science and engineering fair open to all 7th through 12th grade students residing, or enrolled, in Connecticut schools and Fishers Island. An important objective of our program is to attract young people to careers in science and engineering while developing skills essential to critical thinking. Through science fair participation, students are encouraged to pursue independent work using proper research methods.


120 schools and regional fairs send students to the CSEF. These students compete for the 600 available spaces at the state fair.

The Connecticut Science & Engineering Fair is supported by academic and industrial organizations throughout the state. We are a volunteer organization, with funds directed to student awards, fair operations, workshops and educational presentations.
