Regeneron International Science and Engineering Fair (ISEF)

Regeneron ISEF
Up to five NEOSEF 9–12th Grade Grand Prize Winners are selected to participate at the next level of science fair competition, the Regeneron International Science and Engineering Fair (ISEF). ISEF is known as the “Olympics” of Science Fairs where more than 1,700 students from all 50 states and more than 70 countries from around the world compete for more than $4,000,000 in scholarships and prizes.

The ISEF is divided into 17 science and engineering categories and each project is reviewed by at least 6 of the over 800 judges at the fair. The 2023 Regeneron ISEF will take place as an in–person only event in Dallas, Texas, in May 2023. Full vaccination status is required for all ISEF participants.

Only about 27% of the students that participate in the ISEF win awards. The ISEF awards $500 for 4th Place, $1,000 for 3rd Place, $1,500 for 2nd Place, $3,000 for 1st Place and $5,000 for Best of Category. Like NEOSEF, many Special Awards are also handed out at the ISEF by companies, organizations and societies. Since 2000, NEOSEF Grand Prize Winners have earned fifteen 4th Place, three 3rd Place, six 2nd Place, five 1st Place and three Best of Category Awards along with many Special Awards at the ISEF.
