Best STEM Competitions for High School Students
Top high-school STEM competitions for 2026: USACO, AMC 10/12, FRC, Science Olympiad, Regeneron STS, ISEF, and more. Cost, deadlines, college signal, and parent next steps.
Updated May 27, 2026 · 16 competitions
By high school, the question shifts from "what does my kid like?" to "what does my kid go deep on?" The competitions below are the ones with the most college-admissions signal — but signal varies wildly by field. Caltech and MIT weight ISEF and USACO heavily; liberal-arts schools care more about the depth of any one activity than the brand of the contest.
Three patterns to plan around: (1) qualifier-style contests (AMC, USACO) need 2+ years of ramp; you can't pick them up senior year. (2) Research-track competitions (ISEF, STS) need a 1-2 year mentored project; the application due date isn't when the work starts. (3) Team competitions (FRC, Science Olympiad) reward leadership roles in 11th and 12th grade more than mere participation in 9th.
How we picked these
This list weights three signals: admission impact (does a top placement actually move the needle at selective universities?), scalability (can a motivated 9th-grader still qualify, or is the field locked up by elite specialists?), and infrastructure cost (does it require a $30k FRC team budget, or can a kid do it alone with a laptop?). The mix gives parents and students a realistic menu — not a pure prestige ranking.

Frequently asked questions
Which competition matters most for college applications?
Depends on the school and major. For T20 STEM admissions: USACO Platinum, AMC 12 → AIME → USAMO, ISEF/STS finals, and FRC Dean's List Finalist are all clear positive signals. Beyond the top-15 schools, depth in any one of these is more important than presence in all of them.
Can my child still start as a 10th or 11th grader?
Yes for project-based comps (CAC, ISEF, research-track). Very hard for olympiad-style ladders (USACO, AMC, USAMO) without prior background. The cards mark "ramp time" so you can plan honestly.
What about international students?
USACO accepts international participants but only U.S. students count for USACO USA selection. ISEF requires qualifying through an affiliated fair (most countries have one). Most other comps on this list are U.S.-only.
