How many olympiad programs are listed for high school students? ExtracurricularHub currently lists 52 verified olympiad opportunities for high school students, each with cost, eligibility, deadline, and an official application link. ### Are any of these olympiad programs free? Yes — 28 of the programs featured on this page charge no participation fee. Free programs are often funded and can be more selective, so apply early. ### Which deadlines are coming up soonest? The next deadlines: International Mathematical Olympiad Team Member (July 8, 2026); International Chemistry Olympiad Team Member (July 18, 2026); Mathematical Olympiad for Girls (September 1, 2026). Deadlines change every cycle — always confirm on the program's official site. ### Do olympiad extracurriculars help with college admissions? Yes — sustained, escalating involvement in olympiad (participation → awards or leadership → independent work) reads far stronger than scattered one-off activities. Pick one or two programs from this page and go deep. ## Related pages - [Competitions for High School Students](https://extracurricularhub.com/extracurriculars/competitions) - [Math Programs & Competitions for High School Students](https://extracurricularhub.com/extracurriculars/math) - [Physics Programs & Competitions for High School Students](https://extracurricularhub.com/extracurriculars/physics) - [Biology Programs & Competitions for High School Students](https://extracurricularhub.com/extracurriculars/biology) - [Browse all extracurriculars](https://extracurricularhub.com/extracurriculars) - [Find My Fit — 3-minute matching quiz](https://extracurricularhub.com/find-my-fit) --- Canonical page: https://extracurricularhub.com/extracurriculars/olympiad Source: ExtracurricularHub (https://extracurricularhub.com) — a free directory of 1,826 verified extracurricular programs for high school students.
