15 Best Summer Programs for High School Students

Most "best summer programs" lists are ranked by nothing. They mix free national research programmes with open-enrolment paid courses, quote acceptance rates that no programme publishes, and link to pages that moved two years ago.

This list is grouped by the two things that actually decide whether you can apply: what it costs and who is eligible. Every number comes from the programme's own site.

At a glance

Free, selective, and worth structuring a year around

1. Research Science Institute. The benchmark. 100 students at MIT each summer at no cost, with an additional 50 places at Stanford from 2027. One week of intensive STEM classes, a five-week research internship, a final week of presentations. The catch that eliminates a lot of applicants: juniors are eligible and seniors are not. Applications for 2027 closed at 11:59pm on 11 December 2026.

2. MITES Summer. Six weeks at MIT, late June to early August, free of charge with room and board covered — students pay only travel. Open to high school juniors who are US citizens or permanent residents. Applications open in the autumn of junior year.

3. Simons Summer Research Program. Stony Brook's flagship. No programme fees or tuition. You must be in 11th grade when you apply, 16 by the start, and a US citizen or permanent resident — visa holders without a green card are explicitly ineligible. The unusual requirement is nomination: a designated school official must nominate you, and each school may nominate only three students, so there is a selection round inside your own school. Deadline 5 February 2027, $75 application fee with waivers available.

4. Anson L. Clark Scholars Program. The smallest cohort of any well-known programme: twelve students, seven weeks at Texas Tech from 21 June to 6 August 2026, a $750 stipend on completion of a successful research report, and no participation fee — room, board and meals covered. You must be 17 by the start date and graduating in 2026 or 2027. US citizens and permanent residents only; the page says "NO EXCEPTIONS".

5. SIMR. Stanford's medical research programme, 8 June to 30 July 2026, about eight weeks. Juniors and seniors, 16 by the start date with no exceptions, US citizens or permanent residents living in the US. Students within roughly an hour of the Bay Area get preference. Stipends are limited and needs-based — generally for adjusted gross income under $80,000 — not a flat payment to everyone, whatever the aggregator guides say.

6. Summer Science Program. The one genuinely open to international applicants. Around 700 participants were admitted in 2026, admission is need-blind, and selected participants who would otherwise have to work over the summer can receive $3,000 stipends. Disciplines are astrophysics, bacterial genomics, biochemistry and cell biology. Note the site has moved from summerscience.org to ssp.org, so older guides point at a dead address.

Paid research placements

These put you in a real lab and charge for it. That is a defensible model — somebody has to cover consumables — but check the geography first.

7. Garcia Center, Stony Brook. A $4,000 laboratory usage fee for roughly six weeks, 24 June to 7 August 2026, with housing a further $2,599 for a double, a $66 health services fee and a $50 registration fee. Entry requirements are specific: an unweighted GPA of 95/100, three of English, Chemistry, Mathematics and Physics, standardised scores at the 60th percentile or above, and three references.

8. UT Austin High School Research Academy. $4,500 flat for 7 June to 14 July 2027, with a $400 non-refundable deposit credited against it. You must be 15 by 1 June. The limitation that catches people: the programme "cannot accept out-of-state or international applicants." Participants can earn three credit hours through UT Extension. We cover it in more detail in our guide to the UT Austin programme.

Free, selective, and UK-only

If you are at school in the UK, this is the group to start with, because the applicant pools are smaller than they should be.

9. Nuffield Research Placements put Year 12 students into real research projects over the summer at no cost, with priority for students who face barriers to progression. 10. Sutton Trust UK Summer Schools are free residential weeks at UK universities for students meeting widening-participation criteria. 11. UNIQ is Oxford's own free residential programme. 12. In2STEM places students with STEM professionals.

We have individual guides to Nuffield, Sutton Trust, UNIQ and In2STEM, including the eligibility rules, which are the part most students get wrong.

Paid pre-college courses

Legitimate, well-taught, and not selective in the way the programmes above are.

13. Harvard Secondary School Program. $15,980 for seven weeks residential in 2027 — $7,960 tuition for the required eight credits plus $7,820 room and meals, with $75 application and $200 programme fees. Four weeks residential is $9,260; commuting or online runs $4,180 to $8,160.

14. Brown Pre-College. From $3,748 for one residential week of Summer@Brown in 2026, rising to $10,858 for five weeks hybrid. Its Oxford-based BEE programme is $8,270 for twelve days.

Both are good experiences. Neither is a selection signal, because the test was payment. Our comparison of free and paid research programmes sets out when the spend is justified.

The option nobody ranks

15. A placement you arrange yourself. Email faculty at a university near you and ask whether they host school students over the summer. It costs nothing, it happens where you live, and it does not appear on any list because nobody profits from it.

Two things to know first. Many wet labs cannot host under-18s: the University of North Carolina's minors in laboratories policy shows the kind of age and supervision rules that make it difficult. And reply rates are low — the University of Arizona's careers service suggests contacting three to five faculty members, which is a useful calibration. Computational, archival and data-based groups face neither problem as sharply.

Our guide to emailing a professor about research covers what the message should say.

What this list tells you

Three patterns are worth noticing. The most selective programmes are free. The most expensive are the least selective. And the deadlines for everything in the first group fall between December and February — six to eight months before the summer they govern.

If you take one thing from this list, make it that timing point. Merit decides who gets in among the people who applied on time, and most students never join that group.

Frequently asked questions

Which summer programme is the most selective?

On cohort size, the Anson L. Clark Scholars Program at Texas Tech takes twelve students a year. The Research Science Institute takes 100 at MIT with a further 50 at Stanford from 2027, drawn from a national and international applicant pool. Neither publishes an acceptance rate, and nor do the other selective programmes on this list, so any percentage you see quoted is an estimate.

Are there good free summer programmes for international students?

The Summer Science Program admits international students and uses need-blind admission. Most of the other free US programmes — MITES, Simons, SIMR, Clark Scholars — require US citizenship or permanent residency with no exceptions. UK students have their own free options, including Nuffield Research Placements and UNIQ, which are open only to UK applicants.

Do I need a teacher to nominate me?

For some, yes. The Simons Summer Research Program requires nomination by a designated school official, and each school may nominate at most three students, so there is an internal competition before the external one. Ask your school in September, not February.

What is the cheapest way to do real research over the summer?

Arranging a placement yourself at a local university, which costs nothing but your time writing emails. After that, the free selective programmes if you are eligible. Paid pre-college courses are the most expensive option and the least selective, which is the opposite of what most students assume when they apply.

How early do applications close?

Earlier than the summer they relate to by six to eight months. RSI's 2027 applications closed on 11 December 2026. MITES and Simons deadlines fall in early February. SIMR's 2026 deadline was 21 February. If you are starting to look in April, the selective options for that summer have gone.

Does a programme name matter to admissions tutors?

Less than students hope and more than nothing. A free programme with a small cohort is a selection signal, because somebody with no commercial interest chose you. A paid course is not a selection signal, because the only test was payment. In both cases what you can describe doing is what carries the application.
