The Regeneron International Science and Engineering Fair (ISEF) is an annual science fair in the United States.^[1] It is owned and administered by the Society for Science,^[2] a 501(c)(3) non-profit organization based in Washington, D.C.^[3] Each May, more than 1800 students from roughly 75 countries and territories compete in the fair for scholarships, tuition grants, internships, scientific field trips and the grand prizes, including one $75,000 and two $50,000 college scholarships. All prizes together amount to over $8,000,000.^[4] Two major awards ceremonies are the Special Awards Organization Presentation (which now includes the Government Awards Presentations) and the Grand Awards Ceremony. The International Science and Engineering Fair was founded in 1950 by Science Service (now the Society for Science) and was sponsored by Intel from 1997 to 2019.^[5][6] Regeneron Pharmaceuticals became the title sponsor for ISEF in 2020,^[7] but the event was cancelled that year and replaced with an online version due to the COVID-19 pandemic.
