15 Competitive STEM Programs for High School Students

If you want to test your STEM skills against the best students in the country without committing to a long internship, a competitive STEM program is worth serious consideration!

These programs are intense, selective, and built around problem-solving, so you get to prove what you actually know instead of just learning about it. Unlike a regular class or a casual summer camp, a competitive STEM program pushes you to perform under real pressure, against students who take the subject just as seriously as you do. That’s the real edge here: you walk away with a result that actually means something!

What do competitive STEM programs for high schoolers include?

Competitive STEM programs put you through the kind of work that separates a strong student from a genuinely exceptional one. You might work through advanced math problems, build and defend an engineering solution, run a real research project, or compete head-to-head in coding or robotics challenges. What you walk away with isn’t just a certificate; it’s proof you can perform at a high level when it counts.

This kind of experience also does real work for college applications. Admissions officers see plenty of good grades, but a strong result in a competitive STEM program shows you can hold your own against a tough, national, or international field. Most programs in this list accept fewer than 10% of applicants, and some admit just 1–2%, making them as competitive as admissions to many top universities. 

With that, we’ve put together a list of 15 competitive STEM programs for high school students! If you’re looking for online STEM programs, check out our guide here.

Frequently Asked Questions

What makes these STEM programs so competitive?
Most of these programs receive far more applications than they can accept, with several admitting under 5% of applicants and some, like RSI, accepting as few as 1.5% to 2.5%. Selectivity comes from a combination of strong academic records, demonstrated research interest, and limited mentor capacity, since nearly every program pairs you one-on-one or in a small group with a faculty member or graduate student.

Do you need prior research experience to apply?
Most of these programs don’t require prior research experience, since they’re designed to teach the full research process from the ground up. That said, strong academic performance in relevant coursework is typically expected, and some programs, like the Summer Science Program, have specific prerequisite coursework requirements you’ll need to meet before applying.

Are these programs free to attend?
Most of the campus-based programs are. MIT PRIMES, MIT’s RSI, NIST SHIP, Rockefeller’s SSRP, Johns Hopkins’ ASPIRE, Northeastern’s YSP, and the Princeton Laboratory Learning Program are all free, and several also provide a stipend on top of being free. The Summer Science Program is a partial exception, using an income-based sliding scale that’s free for lower-income families but charges a fee otherwise. Horizon’s cost varies depending on the program type you select, but financial aid is available there as well.

Which programs offer the highest stipends?
The Carl B. & Florence E. King Foundation Summer Program at MD Anderson offers a $7,200 stipend, and NYU’s ARISE program and the Anson L. Clark Scholars Program also provide stipends, at $2,000 and $750 respectively. It’s worth factoring in stipend amounts alongside program fit and acceptance odds when comparing your options.

Which programs are restricted by geography or residency?
Several of these programs limit eligibility based on where you live. NIST SHIP requires living within 50 miles of a NIST campus, the Princeton Laboratory Learning Program is limited to New Jersey residents, NYU’s ARISE program requires NYC residency, and Northeastern’s YSP requires commuting distance to Boston. Horizon, by contrast, has no geographic or U.S.-residency requirement, since the program runs entirely online.

Is there a way to pursue independent research without competing against a highly selective, low-acceptance-rate applicant pool?
Yes. If you’d rather work one-on-one with a mentor on a subject you choose than compete for a handful of spots, Horizon’s Research Seminars and Labs pairs you with a professor or PhD scholar to develop a 20-page research paper you can submit for academic publication. The program also provides a letter of recommendation and detailed feedback, and covers over 600 research specializations. You can find the application here.

When should you apply?
Deadlines for these programs are spread throughout the year, so it helps to plan ahead. Rockefeller’s SSRP has one of the earliest deadlines at January 2, followed by MIT PRIMES (December 1) and MIT’s RSI (December 10). January brings a cluster of deadlines, including NIST SHIP and the Carl B. & Florence E. King Foundation Summer Program, while February and March round out the year with deadlines for SIMR, SAMS, ARISE, and Northeastern’s YSP. Horizon, by contrast, has multiple deadlines throughout the year across its Spring, Summer, and Fall cohorts, giving you more flexibility if you miss an earlier cutoff.
