Broad Summer Scholars Acceptance Rate 2026
Updated: 29th October, 2026
TL;DR
The Broad Summer Scholars Program doesn't publish an acceptance rate, but it's a small, paid, six-week research program for Massachusetts juniors. Only students at Massachusetts high schools within commuting distance of the Broad can apply, and the 2026 scholars page lists 18 students. Applications for the 2027 cycle open November 23, 2026 and close January 20, 2027. If you live elsewhere or can't commit to a full summer, look at the Lumiere Research Scholar Program. It pairs you 1:1 with a PhD mentor for online research.
Does the Broad Summer Scholars Program publish an acceptance rate?
No. The Broad Institute does not post a percentage anywhere on its official pages. Any exact rate you see online is an estimate, not a figure the program confirms. The program FAQ (as of October 2026) describes how it reviews applicants but never gives a number. Treat round figures with care, and plan around what the program really controls. The table below shows the numbers the official pages do give.
Figure | Detail | Year or cycle | Source |
Acceptance rate | Not officially published | 2027 cycle | |
Cohort size | Not officially published. The 2026 scholars page lists 18 students | 2026 | |
Cost and stipend | Paid, no program fee. Amount not listed on the 2027 page | 2027 cycle | |
Application deadline | January 20, 2027 (opens November 23, 2026) | 2027 cycle | |
Program dates | July 6 to August 13, 2027 (6 weeks) | 2027 cycle | |
Eligibility | Rising senior at a Massachusetts high school within commuting distance, B or better in science and math | 2027 cycle |
How selective is it, really?
Very. The program caps a small group each summer and pays every scholar. Paid slots and a six-week, full-time schedule keep the cohort small on purpose. The 2026 scholars page lists 18 students (as of October 2026), and Lumiere's deep dive on the Broad Summer Scholars Program describes fewer than 20 students per year. A small cohort plus a Massachusetts-only rule makes each seat competitive.
Who gets into BSSP, and what does it look for?
Strong, curious science students with room to grow. The program reads the whole application and picks scholars only on its published criteria. Reviewers look at coursework, extracurricular interests, enthusiasm for science, teacher recommendations, and what you would add to the Broad community. You do not need prior research experience. The official program page says students with limited STEM participation are especially encouraged to apply. Real enthusiasm for biology and genomics matters more than a polished resume.
Who is eligible to apply to the Broad Summer Scholars Program?
The gate is narrow, and it is the biggest filter. You must attend a high school in Massachusetts and live within daily commuting distance of the Broad in Cambridge. Students outside Massachusetts cannot apply, even if they arrange their own housing. You apply during junior year and attend as a rising senior. You also need a B or better in science and math classes. You must be a US citizen, permanent resident, or non-citizen with employment authorization, per the official page (as of October 2026).
When is the application deadline and when does the program run?
The 2027 application opens November 23, 2026 and closes January 20, 2027. The program itself runs July 6 to August 13, 2027, for six weeks. Notifications go out in mid to late March 2027, so expect a wait after you apply. These dates come from the official Broad Institute page (as of October 2026). Scholars attend daily from 9:00am to 5:00pm, per the program FAQ, and can't be in other courses or programs, or hold other jobs, during program hours.
Does BSSP pay a stipend, and is there a cost?
Yes, it pays you, and there is no program fee. The official 2027 page calls it paid but does not list the amount (as of October 2026). Confirm the current stipend when the application opens. Lumiere's BSSP review reported $3,600 for the 2024 cycle. A paid program with no fee is rare at this level, which is part of why demand runs high.
How can you improve your chances of getting in?
Focus on the parts you control. Keep your science and math grades strong, since a B or better is the floor. Ask a science teacher early for a recommendation that speaks to your curiosity, not just your grades. Write application answers that show interest in the kind of work the Broad does, like cancer biology or genomics. If you cannot commit to the full six weeks, wait for a year when you can. Partial attendance is not allowed.
How does BSSP compare to other research programs?
BSSP is one of a few paid, in-person options in the state. For context, see Lumiere's roundups of research programs for high school students in Massachusetts and free summer programs in Massachusetts. Most strong summer research programs are selective and do not publish acceptance rates, so compare them on cost, format, and who teaches. If where you live or the summer window rules BSSP out, look for a research option you can do online.
Is the Broad Summer Scholars Program worth it?
For eligible Massachusetts juniors, yes. It's paid, free to attend, and gives you six weeks of lab research. The tradeoff is time and location, as the official page requires the full six weeks.
Pros -
It's paid and has no program fee, so cost won't block you.
You don't need prior research experience, and students with limited STEM participation are encouraged to apply.
You get six weeks of original biomedical research at the Broad Institute, plus a poster session and college readiness support.
The small cohort of about 18 students means a lot of attention from mentors.
Cons -
Only juniors at Massachusetts high schools within commuting distance can apply.
You must attend every day from 9:00am to 5:00pm for six weeks, so you can't take other courses or jobs.
The acceptance rate isn't published, so you can't judge your odds from a number.
The stipend amount isn't listed on the 2027 page, so you can't plan around it yet.
Frequently asked questions: Broad Summer Scholars Program acceptance rate for high school students
What GPA do you need for the Broad Summer Scholars Program?
The program does not set a GPA cutoff. It asks for a B or better in your science and math classes, per the official page (as of October 2026). Beyond that bar, reviewers weigh your full record and your interest in science. Strong grades help, but they are not the only factor.
Can out-of-state students apply to BSSP?
No. You must attend a high school in Massachusetts and be able to commute to Cambridge each day. The program FAQ states that students from neighboring states and students who live outside Massachusetts cannot apply, even with their own housing. This residency rule is the single largest filter on the applicant pool.
Do you need research experience to join BSSP?
No. The program says you don't need prior research experience. Instead, it looks for curiosity and interest in Broad research areas, which you can show in your application materials. The official page also says students with limited STEM participation are especially encouraged to apply.
What do BSSP scholars do all summer?
You work on a mentored biomedical research project for six weeks. The official page also lists a poster session, college readiness coursework, a career mixer, scientific talks, and social events. The program FAQ adds a first-week wet lab training and weekly one-on-one academic support. Expect full days, from 9:00am to 5:00pm.
Does BSSP help with college admissions?
A selective, paid research program on your application shows initiative and lab experience. It will not get you in on its own, and no program should promise that. What helps most is what you do with the work, like a strong poster or a clear story about what you learned. Depth of experience reads better than the name alone.
What should you do if you're not eligible for BSSP?
Plenty of students live outside Massachusetts or can't free up six full weeks. In that case, look for a mentored research path you can do from anywhere, or for a program near you with a different schedule. Lumiere's list of free summer programs in Massachusetts is a good place to compare options. Check each program's own page for current eligibility and dates.
Live outside Massachusetts, or can't give up six full weeks of 9-to-5 days? Look at the Lumiere Research Scholar Program. It pairs you 1:1 with a PhD mentor for an independent research project done entirely online, with no residency rule and no daily on-site schedule. Apply here.
