The Siemens Competition in Math, Science & Technology, previously known as the Siemens- Westinghouse Science Talent Search, is one of the most distinguished research competitions in the United States. Students enter the Competition in hopes of achieving national recognition for their research and of winning one of the many college scholarships that are awarded at the higher levels of the competition. The Competition is sponsored by the Siemens Foundation and administered by The College Board. The Siemens Foundation provides nearly $2 million in scholarships each year through the Foundation's many programs such as the Siemens Competition and the Siemens Awards for Advanced Placement. Through its generous funding, the foundation strives to inspire the scientists of tomorrow by supporting them today.

Applicants conduct original research and write a paper on their project. While many students conduct their research at universities, hospitals, and corporations, some of the most successful projects in Siemens history have been so-called "basement projects"; the research was conducted at home or at another location not associated with a research institution. Students may enter the competition individually or in teams of two or three members. Only seniors in high school can submit individual projects whereas teams can be comprised of students in any grade in high school.

Unlike other research competitions, the Siemens Competition focuses purely on students' research and the extent to which students are versed in the field of their specific research project. The Siemens Competition also distinguishes itself from other research competitions by having a timeline that allows successful applicants to notify colleges of their recognition in the Competition before early application decisions come out. While this competition may be very tough, the fruits are very well worth it. Applicants who advance to the regional finalist level of the competition or higher have the opportunity to meet students from around the country who share the same interest in research. Success in the competition also often opens many doors for internships, positions in labs, and other educational and career objectives. The money is not that bad of a perk as well.
