The 2021 Connecticut Science and Engineering Fair will be virtual.  School and project registrations are open!  We recognize the challenges many schools currently face.  We are lowering our project registration fee from $45 to $35 per project for 2021.

Schools must register for the Connecticut Science and Engineering Fair by October 30, 2021.  Please use THIS link to register your school.   School registration should be completed by an authorized faculty or staff member. Students should not complete school registration.  Schools register for “slots” at the Fair.  Once a school is registered, individual students can register their projects in “Project Registration.” Schools make the determination as to which students and projects attend the Fair.

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.
