Are you a student eager to explore science within a competitive framework, or looking for a team endeavor beyond athletics? Science Olympiad offers exactly that, and at a scale few competitions match. Founded in 1984, it is the leading team STEM competition in the nation, with about 7,000 teams competing across 450 tournaments in all 50 states.
Whether you are a seasoned competitor or brand new to SciOly, this guide covers how the competition actually works, how to join or start a team, how to prepare for the three types of events, and how Science Olympiad differs from the international subject olympiads it is often confused with.
How Science Olympiad Works
Science Olympiad is organized by a national nonprofit and run through state chapters. Teams compete in two divisions: Division B for middle school and Division C for high school, with each division running its own slate of 46 standards-aligned events every season.
Events span the full breadth of STEM, from Anatomy and Physiology to Forensics to engineering builds like towers and vehicles, and the event slate rotates from year to year, so even veteran teams face fresh challenges each season.
Team Sizes
Each team fields up to 15 students, with individual events taken by pairs or trios. That structure is the heart of the competition: no one student can cover 46 events, so success depends on distributing expertise across the roster, managing scheduling conflicts between events, and trusting teammates in their specialties. Team placement is determined by combined performance across all events, which means a deep, balanced team beats a team of a few stars.
SciOly Season
The season follows an annual rhythm. New rules for each season are released in early September as free PDFs on the official site. Then fall and winter bring invitational tournaments hosted by high schools and universities, and the official ladder of regional, state, and national tournaments runs through the spring. Membership runs through your state chapter, which sets registration details and fees for your state.
Joining or Starting a Team
If your school already has a team, attend an interest meeting early. Established teams often hold tryouts or placement processes, and expressing interest early increases your chances of securing a spot on the competing roster.
If your school has no team, you can start one. You will need a sponsoring teacher or coach, though their role can range from active coaching to purely logistical support, so clarify expectations before you begin.
Register through your state Science Olympiad chapter, which lists the process on its website, and note that Science Olympiad's own resources for new teams include event descriptions, webinars, and starter materials.
One more thing worth knowing: STEM obsession is not a prerequisite. Alumni have gone on to careers across every field, and the competition's teamwork, preparation, and communication demands are educational for everyone.
Preparing for the Three Kinds of Events
Every event falls roughly into one of three types, and each demands a different preparation style.
Study Events
Study events reward deep content knowledge, prepared reference materials where the rules allow them, and efficient recall. Flashcards, annotated notes, and past exams are the core tools, and the official event pages and archives are the authoritative source for what each event covers.
Lab Events
Lab events add hands-on technique. Preparation means getting comfortable with the equipment, dividing tasks between partners before competition day, and running the procedures enough times that execution is automatic under time pressure.
Build Events
Build events are engineering projects completed before the tournament: towers, vehicles, flight devices, and similar challenges. Success comes from reading the rules obsessively, since a technicality can disqualify a season of work, then iterating through design, testing, and rebuilding cycles long before the deadline. Official kits and the free rules PDFs define the constraints, and rules corrections published mid-season are required reading for every build team.
Across all three types, the single most common mistake is under-reading the rules. Every event has a detailed rules page, official clarifications are posted during the season, and top teams treat both as living documents.
Competition Day
On tournament day, the fundamentals matter: rest the night before, materials packed per each event's guidelines, comfortable clothes, and structures securely packed for transport.
Build a shared equipment checklist with your teammates weeks in advance, assign responsibility for every item, and run a final check the night before. Establish how you will reach each other quickly during the day, because with 15 students spread across dozens of events and rooms, last-minute adjustments are guaranteed.
Funding Your Team
Competing costs money: state membership fees, travel, uniforms, build materials, and study resources.
Teams fund themselves through school budgets, local business sponsorships, community organizations, and parents, and the strongest pitch highlights what Science Olympiad demonstrably builds: STEM skills, teamwork, and academic growth.
Fundraisers, grant programs aimed at STEM education, and Science Olympiad's own initiatives, including scholarship programs and an Urban Schools Initiative serving high-need regions, round out the funding landscape. If resources are tight, start with your state chapter, which knows what support exists locally.
The Tournament Ladder
Invitational tournaments, hosted by high schools and universities early in the season, are unofficial but invaluable: they are the best practice environment available, and the official organization itself recommends them for exactly that. The official ladder then runs regionals, states, and nationals, with teams advancing on performance, though some states skip regionals and send teams directly to the state tournament. The National Tournament, hosted by a different university each year, gathers the top team or teams from every state, with highly competitive states earning multiple bids.
Science Olympiad vs. the International Olympiads
The name causes endless confusion, so here is the distinction. Science Olympiad is a US team competition: interdisciplinary, 46 events, 15-student rosters, and a national championship as its summit. The International Science Olympiads, like the International Mathematical Olympiad or International Physics Olympiad, are individual, single-subject competitions where national teams of four to six students compete globally after surviving exam-based qualification pipelines.
They reward different strengths. The internationals reward extreme depth in one subject; Science Olympiad rewards breadth, collaboration, and hands-on execution across many. Plenty of students do both, using SciOly's event variety to discover the subject they later pursue to international depth.
From Science Olympiad to Original Research
Science Olympiad often reveals the discipline a student wants to go deeper in, and original research is the natural next step: taking a question from an event you loved and pursuing it beyond any rules manual. Research projects compete at science fairs like the Regeneron International Science and Engineering Fair (ISEF), the world's largest pre-college STEM research competition, where the hands-on skills SciOly builds translate directly.
Want To Do In-Depth Research?
We do not coach for Science Olympiad, but turning scientific curiosity into an award-winning research project is exactly what we do. Our coaches include ISEF Grand Awardees and Regeneron STS Scholars who have built winning projects of their own.
