Stanford Math Tournament: Who Can Actually Compete (Onsite vs. Online)

A high schooler in Lagos can register for the Stanford Math Tournament this year. A high schooler in Palo Alto can get turned away from the onsite event if their school isn’t sending a team.

Same competition name, two different sets of rules, and most overviews online talk about “Stanford Math Tournament” like it’s a single thing with a single door in.

The Stanford Math Tournament (SMT) is an annual math competition for high schoolers, run by Stanford students through the Stanford Undergraduate Mathematics Organization (SUMO).

It splits into two divisions: an onsite competition on Stanford’s campus, restricted to US high schoolers, and SMT Online, open worldwide to any student in high school or below. Which one your student can even register for depends on where they live and how they’re entering, not on how strong they are at math.

What Is the Stanford Math Tournament?

Stanford Math Tournament is a student-run competition for high schoolers, held every spring by SUMO and Stanford’s math department.

It started in 1999, running alongside the Harvard-MIT Math Tournament that year, with a format modeled on the Rice Math Tournament, one of the older university-run contests in the country. It now runs as two separate events each year: an in-person tournament on Stanford’s campus and SMT Online, held a day or two later for a global field.

Both divisions cover the same subjects (algebra, geometry, combinatorics, calculus) at a comparable difficulty. SMT Online isn’t a simplified version of the onsite event. It’s the same tournament, offered a second way for students who can’t get to Palo Alto or who haven’t reached high school yet.

There’s no separate qualifying exam to enter either one. Registering a team by the deadline, and meeting that division’s eligibility rule, is the only gate.

Who Can Compete

Onsite SMT: US high school students only

Onsite SMT is limited to high schoolers currently living in the United States, age 14 or older. Registration happens as a school or organization team of 5 to 6 students.

If your school can’t field a full team, you can register as an individual and get placed on a team of strangers, grouped by geography. Reserved spots exist for strong teams from the previous year and for teams that are low-income or historically underrepresented in competition math, so a solo entry is competing for a smaller share of the room than a full school team.

Getting to campus is part of the commitment. Onsite SMT runs as a full weekend visit, not a single test in an afternoon: students travel in, compete across the individual and team rounds, and the registration fee covers a tournament shirt and shared meals along the way. A student who can’t make that trip isn’t out of options. That’s exactly what SMT Online exists to solve.

SMT Online: open worldwide, high school and below

SMT Online removes the residency rule. Any student in high school or below, in any country, can register a team of 5 to 6 and compete from wherever they are, with individuals able to register directly instead of waiting on a geographic match.

Your eighth grader isn’t locked out of Stanford Math Tournament. They’re locked out of the campus event only, because SUMO runs two full tournaments under one name.

	Onsite SMT	SMT Online
Who can register	US high schoolers, age 14+	High school and below, any country

How Stanford Math Tournament Is Structured

Subject tests and the General Test

Every competitor picks one of two paths for the individual round. Take two Subject Tests: 50 minutes and 10 short-answer questions each, chosen from Algebra, Calculus, Discrete Math (number theory and combinatorics) or Geometry.

Or take the General Test: a single 110-minute exam with 25 short-answer questions, built for students without a specialized background in any one of those four areas. The trade-off is real: the General Test only counts for 60 percent of the points two Subject Tests would earn, so choosing it trades ceiling for accessibility.

That trade-off is exactly where a newer competitor should start. Most guides to Stanford Math Tournament assume you’ve already worked through pages of AIME problems before you register. T

he General Test doesn’t assume that. It’s built for a student with solid grade-level math who hasn’t specialized into calculus or olympiad number theory yet, and that’s a real gap Gonit’s practice format fits. Grade-wise questions, a hint before you answer and a full explanation after a wrong one build the broad footing the General Test rewards across arithmetic, algebra, geometry and logic instead of one deep track.

Gonit’s confirmed grade coverage runs through grade 10 live, with 11 and 12 in progress, right at the edge of SMT’s core grades 9 to 12 audience, so younger competitors in that range get the most direct fit.

The Team Round

The Team Round sits apart from the individual tests: 50 minutes, 15 short-answer questions, worked by the whole team on the same problem set. It carries roughly the same weight as one Subject Test in the standings, and it rewards teams that walked in already used to solving as a group.

Is Stanford Math Tournament Prestigious?

It depends what you’re comparing it to. Next to a school math club or a regional meet: yes. SMT draws several thousand competitors across both divisions each year. It runs in partnership with Stanford’s math department and, in past years, with collaborators including Rice, Columbia and Johns Hopkins.

Next to AIME or the IMO track, it’s a strong credential rather than a golden ticket. SMT sits in the same tier as HMMT, ARML and Math Prize for Girls: elite, university-run, selective by team placement instead of an admissions committee, and a real signal that a student can perform under timed pressure against a national and international field.

None of that guarantees an admissions outcome by itself. Treat it as one strong data point, the way you’d treat an AIME qualification or an ARML team spot.

Selective colleges see plenty of AMC scores every fall. A team result from an elite invitational is a rarer, more specific line on an application, mostly because far fewer students attempt a team-format tournament than sit for the AMC. Rare isn’t the same as decisive. It’s one signal among the many an admissions file carries.

How to Register and What It Costs

Registration numbers move year to year, so treat the figures below as a snapshot of the 2026 cycle and confirm the current cycle directly on stanfordmathtournament.org before you plan around them.

As of this writing, SMT 2027 dates hadn’t been posted yet; SUMO typically opens registration in winter for a spring competition.

For the 2026 cycle: onsite registration cost $30 per student, covering a tournament T-shirt, Friday dinner and Saturday lunch, for a field of roughly 800 students on campus.

SMT Online used a three-tier fee structure that rewarded registering early: $25 per student for Early Bird, $30 for Regular, and $35 for Late. Both divisions require teams of 5 to 6.

FAQ

Stanford Math Tournament isn’t one gate. It’s two, and where your student lives decides which one they can even walk through. Settle that question before you settle on a prep plan.

Then build the broad footing the General Test rewards: grade-wise practice, a hint when you’re stuck, and a full explanation when you get it wrong. Gonit is built for exactly that stretch of practice.
