International recognition; opportunity to present research to leading scientists and engineers; substantial awards and scholarships; exposure to universities and STEM organizations; opportunity to build a highly competitive research portfolio.

Students must be in grades 9–12 or equivalent and must not have reached age 20 by May 1 preceding ISEF.
