Delaware Valley Science Fairs

About

Delaware Valley Science Fairs (DVSF) is a regional STEM science fair for students in grades 6–12 from Pennsylvania, southern New Jersey, and Delaware. Founded in 1949, Delaware Valley Science Fairs, Inc. is a 501(c)(3) nonprofit affiliated with the Regeneron International Science and Engineering Fair (ISEF).

Each year about 900–1,000 students present research in 13 categories, plus Team Projects and (for grades 6–8) Consumer Science. Scholarship and prize money are awarded; top high-school winners advance to Regeneron ISEF, and top middle-school winners to the Thermo Fisher Junior Innovators Challenge.

Next edition

DVSF 2027 is scheduled for 6–8 April 2027 at the Greater Philadelphia Expo Center at Oaks. Hours are not listed on the official homepage yet.

The site still congratulates winners of DVSF 2026. An ISEF 2027 sidebar listing Los Angeles with May 2026 dates appears inconsistent and is not used here.
