Summer Math Programs for High School Students: 15 Real 2026 Options

Here’s something most people don’t know: the best summer math programs in the country are completely free. Ross, PROMYS, MIT PRIMES, RSI, SUMaC with full aid. No tuition. No catch. The only filter is how picky they are about who gets in.

If you want a summer that feels like math camp (the good kind), this guide covers the programs worth your time.

Some are free and competitive. Some cost money but offer strong aid. A few are online and cheaper if you just want to learn without the travel.

One heads-up before you keep scrolling: most of the top programs close between February and March.

You’re reading this at the right time if you start your applications now. Wait until April and you’ll be targeting 2027 instead.

Rolling and Online Programs (Apply Anytime)

If fixed March deadlines feel tight, start here. These programs run rolling admissions, online-first models, or year-round enrollment. You can still apply even if you’re reading this later in the cycle, though spots in the popular ones fill quickly.

HCSSiM (Hampshire College Summer Studies in Mathematics) takes applications until late April with rolling decisions. Six weeks of 4-hour morning classes Monday through Saturday, plus evening problem sessions.

Tuition is $7,208 with financial aid available. If you can turn an application around fast, this is the best in-person bet for summer 2026.

Texas State Honors Summer Math Camp (HSMC) runs 6 weeks, June 21 through August 1, 2026. Tuition is $6,600.

Rolling admissions started February 15 and run through early summer, but spots fill quickly. Worth a shot if you live in Texas or can travel there for six weeks.

Idea Math Summer 2026 has sessions in Boston, California Bay Area, Plano/Frisco Texas, and online.

Tuition starts at $1,675 with early enrollment pricing. The online sessions have later deadlines and are typically still open into April and May.

MOSA (Math Online Summer Academy) is free and covers geometry, number theory, and combinatorics online.

You need to pass an admission test, but once you’re in, all materials cost nothing. Applications are processed year-round, so there’s no hard deadline.

Art of Problem Solving (AoPS) runs structured online classes with homework and real instructor feedback. Classes run $300-500 each.

They have summer sessions plus fall, winter, and spring schedules. Registration usually stays open until the class start date.

AwesomeMath Summer Program had a main February 18 deadline but sometimes accepts late applications depending on session availability. If you email them directly, they may still have room. 3 weeks online, 2.5 hours a day, good for AMC and AIME prep.

For completely free self-study, Khan Academy covers pre-algebra through calculus and into college-level topics. Not a "program" in the traditional sense, but a solid way to level up your skills if none of the options above work out.

The Complete 2026 Program List

Here’s the full landscape. Rolling programs first, then the elite ones with fixed deadlines (most between February and March):

Elite Free Programs (Apply by March)

These are the holy grail of math programs. Fully free, world-class faculty, ridiculously competitive. Most close between February and March, so if you’re reading this early in the year, you still have time to apply. If not, mark them for 2027.

Ross Mathematics Program runs 6 weeks at Ohio State, deep-diving into number theory and abstract math.

It technically costs $7,500, but they offer strong financial aid. Acceptance rate is under 10%. Mostly ages 15-18. The 2026 deadline is March 8. Apply this winter if you haven’t already.

PROMYS at Boston University is basically the Ross of New England. Same 6-week format, same deep number theory focus. The big difference: PROMYS offers full-tuition need-based financial aid, so if money is tight at home, this is the one to push for.

RSI (Research Science Institute) is the most selective free STEM program for high schoolers in the country. MIT hosts it, and 100 students get in from around 3,100 applicants (about 2.5% acceptance). You do real research with a mentor. Math is one of the tracks.

The 2026 deadline was December 10, 2025, so the 2026 application is closed. Start prepping for the 2027 round now if you’re a sophomore or junior.

MIT PRIMES and PRIMES-USA lets you work on research projects with MIT grad students for almost a full year. PRIMES is for Boston-area students, PRIMES-USA is nationwide and fully remote. Free.

The 2026 application closed December 1, 2025. That makes PRIMES a 2027 target. If you’re a sophomore or junior, start prepping now.

CMU SAMS (Summer Academy for Math and Science) at Carnegie Mellon is free, residential, 6 weeks, for rising high school seniors.

It focuses on students from underrepresented backgrounds in STEM. Applications usually open in early spring.

Paid Residential Programs

These cost money but deliver serious value. Deadlines spread from winter through spring, so check each one. If your family can afford tuition or you can pull financial aid, any of these is worth applying to.

SUMaC at Stanford (Stanford University Mathematics Camp) is a 3-week program for rising juniors and seniors. The residential version costs $8,575 and takes 40 students. The online version costs $3,580 and takes 64 students. Financial aid is available based on need.

Canada/USA Mathcamp is a 5-week camp for talented high schoolers. Location changes each year. Less about rigid courses, more about problem-solving culture. Strong community among students. Scholarships cover tuition for many participants.

MathILy at Bryn Mawr is 5 weeks of inquiry-based learning. Seven hours of math a day, six days a week, split morning and evening. Yes, that is the point. It’s built for students who want to eat, sleep, and breathe math for a summer.

Michigan Math & Science Scholars (MMSS) runs 2-week sessions at the University of Michigan. Costs $3,800.

The 2026 deadline is March 15, and sessions typically fill within weeks. Apply as early as possible. Subjects range from cryptography to mathematical modeling.

The Math Competition Path (AMC to USAMO)

If you love competitive math, you’ve probably heard of AMC and USAMO. Here’s how the path works, explained simply:

AMC 10 and AMC 12 are the entry tests. Both are 25-question, 75-minute multiple-choice exams. AMC 10 is for students in 10th grade and below. AMC 12 covers the full high school curriculum. The 2025-2026 dates were November 5 and 13, 2025.

Score well on AMC, and you qualify for the AIME (American Invitational Mathematics Examination). AIME is 15 problems, 3 hours, with answers between 0 and 999. AIME 2026 runs February 5 and 11.

Score well on AIME (the top 11% or so), and you get invited to the USAMO or USAJMO. These are 6 proof-based problems over two days, totaling 9 hours.

USAMO/USAJMO 2026 runs March 21-22. The top scorers head to the International Math Olympiad training.

The algorithmic thinking behind competition math also shows up in programming contests. If coding challenges appeal to you, our best coding internships for high school students guide covers USACO and the competitive programming world that shares this mindset.

Building Toward 2027 (If This Summer Isn’t Right)

If you’re in 9th or 10th grade, or you missed this year’s deadlines, here’s how to build a stronger application than 90% of next year’s applicants:

• Do AoPS classes or Khan Academy all summer. Build your skills with consistent self-study. A strong AoPS track record helps selective programs take you seriously next year.

• Prep for fall AMC 10 or AMC 12. If you’re in 10th or 11th grade, study for the November AMC contests. A strong AMC score is part of why programs accept you.

• Set up a 2027 application tracker now. Mark RSI (Dec 10), MIT PRIMES (Dec 1), Ross (March 8), PROMYS (early spring), SUMaC (winter). Start recommendation requests by September.

• Start a math research project on your own. Pick a question you find interesting. Work through it all summer. Document your process. This alone often beats a summer camp on college applications.

• Read one real math book cover to cover. Try "Concrete Mathematics" by Knuth or "Number Theory Through Inquiry" by Marshall, Odell, and Starbird. Working through a real math book shows real math maturity on your application.

How to Stand Out in Applications

These programs get way more applications than they can accept. What makes your application memorable:

• Solve the application problem set with real depth. Ross and PROMYS both use problem sets to judge applicants. Don’t just get answers. Show your reasoning, try multiple approaches, explain what you tried that didn’t work.

• Describe a math thought that surprised you. One that kept you up at night. This beats generic "I love math" essays every time.

• Get a math teacher recommendation. Not your English teacher. Your math teacher who’s watched you puzzle through hard problems and keep going.

• Mention your AMC scores if they’re strong. Even Bronze-level USACO or a solid AMC 10 placement helps.

• Keep it honest. Don’t exaggerate your level. Programs match you to the right track. Say where you are and let them work with it.

Application Timeline (Plan Your Year)

The math program year runs on a predictable calendar. Use this to plan for 2027 (or catch up if you’re behind on 2026):

Frequently Asked Questions

Do I need to be a math genius to apply?

No. You need to love math and be willing to work hard on challenging problems. Ross and PROMYS judge you on effort and reasoning, not just correct answers. Most programs accept students at various skill levels, not just olympiad champions.

What if I haven’t taken the AMC?

You’re not disqualified. Many top programs accept students without AMC scores. Strong grades, an interesting application essay, and a solid teacher recommendation can make up for it. That said, take AMC this fall if you can.

Are these programs worth the money?

Free programs like Ross, PROMYS, RSI, MIT PRIMES, and SAMS are clearly worth it if you can get in. Paid programs like SUMaC and MMSS deliver real value if your family can afford them. If money is tight, push for financial aid or try Canada/USA Mathcamp which offers solid scholarships.

Do colleges really care if I went to Ross or PROMYS?

Yes, but maybe not the way you think. Ross or PROMYS on your application signals that you can handle serious math and stuck with a 6-week program full of hard problems. Admissions officers at top schools know these programs. But what matters more is what you DO with the experience: the research you continue after, the math club you start, the AMC scores that go up. The program is a platform, not the finish line.

Can I do more than one program in a summer?

Usually no. The residential programs overlap in dates and each takes 2-6 weeks. Pick your top program and give it full attention. If you finish early, add AoPS online or a self-study project.

What if I’m only in 9th or 10th grade?

Most elite programs accept 10th-11th graders. For 9th graders, focus on AMC 10, Khan Academy, and AoPS intro classes. Build your foundation now. Apply to the big programs in 10th or 11th grade.

Final Word

Summer math programs for high school students are real, varied, and more accessible than they look. The free ones are incredibly competitive but worth every application hour.
