It is owned and administered by the Society for Science, a 501(c)(3) non-profit organization based in Washington, D.C. Each May, more than 1500 students from roughly 70 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 $5,000,000.[4] Two awards ceremonies are held including: Special Awards Organization Presentation (which now includes the Government Awards Presentations) and the Grand Awards Ceremony.
