Best Science Research Competitions for High School Students
Regeneron STS, Regeneron ISEF, Science Olympiad, Brain Bee — the research-track competitions admissions officers know. With qualifying pathways, deadlines, and how to start.
Updated May 27, 2026 · 9 competitions
Research-track competitions are different from olympiads in a fundamental way: they reward original work, not test scores. That means the timeline starts long before the application — typically 1-2 years of mentored research under a professor, summer-program PI, or industry scientist.
The two apex sources (STS and ISEF) read similar in admissions but have different application shapes. STS requires a senior-year written report; ISEF requires winning your affiliated regional or state fair the same year. Most serious research-track students compete in both. The two below them (Science Olympiad, Brain Bee) are accessible without mentored research and serve as on-ramps.
How we picked these
For research-track competitions, "best" means "best signal for STEM-track college admissions." We've ranked by which competition's alumni show up most often at MIT, Caltech, and Stanford STEM programs, weighted by accessibility (can a motivated 10th-grader still apply?).

Frequently asked questions
How does my child get started in research?
Three common paths: summer research programs (RSI, SSP, MITES — apply junior year), university lab outreach (cold-email professors near you in 10th-11th), and citizen science (community.scifeds.org has projects you can start at home). Most STS/ISEF finalists started in 10th grade.
What if we don't live near a research university?
Remote mentorship is now common. Polygence, Lumiere, and Veritas AI offer paid programs. The Society for Science's Outreach grants fund students from under-resourced schools. The work matters more than the prestige of the supervising institution.
