The Siemens Competition in Math, Science & Technology recognizes remarkable talent early on, fostering individual growth for high school students who are willing to challenge themselves through science research. Through this competition, students have an opportunity to achieve national recognition for science research projects that they complete in high school. It is administered by The College Board and funded by the Siemens Foundation.  Up to 300 projects from almost 2,000 submissions are recognized as Semifinalists, while the top 30 individual and 30 team projects are invited to compete in the Regional Competitions, held at six partner universities.
