Alaina Gassler is a ninth grader from West Grove, Pennsylvania, and the recipient of this year’s $25,000 Samueli Foundation Prize, the top award at the Broadcom MASTERS.

Students in grades 9-12 or equivalent must compete in a Regeneron ISEF affiliated science fair and win the right to attend Regeneron ISEF.  Each affiliated fair may send a pre-determined number of projects to ISEF (as calculated by participation and high school population) to compete in 22 different categories.

The ISEF Scientific Review Committee (SRC) has attempted to provide answers to questions that they commonly receive about the International Rules and Guidelines.

If your institution or organization is interested in a unique way to engage with top international high school STEM talent, the Regeneron International Science and Engineering Fair (ISEF) is your opportunity to do just that.
