TL;DR
Here’s what’s below: what Texas Tech actually publishes about Clark Scholars selection, the eligibility rules, whether you get another shot, programs still open, and a two-week plan to turn this into real work. Clark Scholars takes 12 people a summer. Twelve. If what you actually wanted was a mentor and a paper with your name on it, you don’t have to wait until next summer to start. Apply to the Horizon Academic Research Program.
Twelve. That’s how many students Texas Tech takes into Clark Scholars every summer, chosen from a pool that spans the whole country and a fair bit of the world.
So before anything else: the odds were terrible for everyone, including people with better scores than you and people with worse ones. Let’s go through what the numbers really say, the rule that trips up more applicants than you’d think, whether you can try again, and what to actually do with the next few months.
What is the Clark Scholars Program acceptance rate?
Texas Tech doesn’t publish one. No applicant count, no percentage. You’ll see “2%” and “3%” thrown around on other sites, but that’s a guess being passed from one blog to the next, not something the university released.
What Texas Tech does tell you is the cohort size, which honestly says more:
| What Texas Tech states | Figure |
| Participants each summer | 12 |
| Program length | Seven weeks |
| Stipend | $750, tax free |
| Room and board | Included |
| Eligible grades | Juniors and seniors |
| Age requirement | Must be 17 by the start date. No exceptions |
| International students | Eligible and welcome to apply |
| Judged on | Academic accomplishments, teacher recommendations, career objectives |
Twelve seats. Open to the whole country plus international applicants. Free, paid, seven weeks on a real research campus.
You don’t need a percentage to see what that does. Offer that to every strong junior and senior out there, then hand out twelve spots. Almost everyone who deserved one didn’t get one. That’s math, not a verdict on you.
And the thing that decided it was probably something you couldn’t touch. Which faculty had room for a student that summer. Which research areas were already taken. Whether your subject lined up with a mentor who happened to be free. Your rejection is sitting in a scheduling spreadsheet somewhere, not in your transcript.

The rule that knocks people out before the essays get read
This one catches people, so check it now: you have to be 17 by the program start date. Texas Tech writes “NO EXCEPTIONS” in capitals.
If you’re a young junior, that can end your application no matter how good everything else is. There’s no appeal and no grey area. Go check your birthday against the start date before you put another cycle into this.
Good news, though. Clark takes juniors and seniors, so for most people the age problem sorts itself out in a year.
Can you apply to Clark Scholars again?
Yes, and that’s a real advantage over most programs at this level.
Because they take juniors and seniors, a rejected junior can come back as a senior. Lots of comparable programs don’t work that way. RSI is juniors only, so a rejected junior there is just done.
But reapplying only works if something’s different. Send the same application and you’ll get the same answer. They’re judging academic accomplishments, teacher recommendations and career objectives, so here’s what you can actually move in twelve months:
- Research you’ve finished, with something written to show for it
- A teacher or mentor who can talk about your research ability specifically, not just your grades
- A sharper answer to what you want to study and why
The first one unlocks the other two. Someone who’s watched you build a question, dig through the literature, and write up a result has something real to say about you. Someone who’s only seen you in class writes a class letter.
That’s the whole case for spending this year doing research instead of waiting for it. Horizon Labs run year-round, one-on-one with a PhD or post-doc, and you finish holding a paper. That’s exactly the thing that changes a second Clark application.
What should you do in the next two weeks?
Rejections hurt less once you’ve put something real in the gap. Here’s a fortnight that works.
Days 1 to 3: pick a question, not a subject. Not “I’m into biomedical research” but “does X change Y in Z.” If that sounds impossible right now, our guide to choosing a research topic shows you how to narrow it, and the mistakes students make picking a focus covers the usual traps. Need prompts to push against? Try the lists for STEM and humanities.
Days 4 to 7: read five real papers. Actual papers, not summaries, not AI overviews. Start on Google Scholar or Semantic Scholar, and our roundup of free databases has more. You’re hunting for the line in the discussion where the authors admit what they couldn’t do. That gap is usually where a high school project fits.
Days 8 to 10: apply somewhere that’s actually open. Table’s below. Apply to more than one. Our lists of research mentorship programs and paid summer research programs widen things out, and if money’s tight, start with free online STEM research programs.
Days 11 to 14: make a file. A two-page proposal. An annotated bibliography. A literature review. Something that exists on your laptop instead of in your head. The students who bounce back fastest are holding a document within a month. For the long version, writing a research paper in 90 days has the full timeline.
Want the structure instead of doing all this alone? That’s what Horizon is. A PhD or post-doc instructor, a deadline, and a finished paper at the end. Start your application.
What research programs are still open?
Clark isn’t the only route, and plenty of these run on different calendars. Deadlines move every year, so check each site before you apply.
| Program | Format | Cost | Who it suits |
| Horizon Academic Research Program | Online, 1-on-1 or small group, 10 to 16 weeks | $6,950, need-based aid available | Year-round starts. You finish with a paper |
| SIMR (Stanford) | In person, 8 weeks, summer | Free, stipend | Biomedical, if you can get to the Bay Area |
| RSI (MIT) | In person, 7 weeks, summer | Free | Juniors only, 100 seats |
| MITES (MIT) | In person or online, summer | Free | STEM enrichment, good on access |
| Research competitions | Varies | Usually free | Anyone who already has a project |
More in our roundups of the most prestigious summer research programs and competitive research programs. Don’t want to wait for summer at all? We track research you can do during the school year too.
One thing on strategy. Firing off five more applications to twelve-seat programs is the same move that just didn’t work. Keep the long shots. But add one route where the outcome depends on your work and not on how many faculty mentors were free that July.
How does Horizon compare to Clark Scholars?
Side by side, using what each program says about itself.
| Clark Scholars | Horizon Academic | |
| Students per year | 12 | Up to 200 |
| Admit rate | Not published | About 26% |
| Cost | Free, plus $750 stipend and room and board | $6,950, need-based aid under $75,000 household income |
| Format | In person in Lubbock, 7 weeks, summer only | Online, year-round cohorts |
| Eligibility | Juniors and seniors, must be 17 | Grades 9 to 12, most admits in 10 and 11 |
| Entry bar | Not published | 3.67 unweighted GPA or equivalent |
| International students | Eligible | Eligible, and it’s fully online |
| Mentorship | Faculty researcher | 1-on-1 with a PhD or post-doc, or a 3 to 6 student seminar |
| What you leave with | Lab experience, seminars, field trips | A capstone paper, about 5,000 words, graded on a university rubric |
| Publication support | Not listed | Up to 3 rounds of journal submission support (Labs) |
| Time | Full time, residential, 7 weeks | 8 to 10 hours a week, 100+ hours total |
Clark is free, it pays you, and it puts you in a real lab for seven weeks. None of this is an argument that it isn’t great. If you’re eligible next year, go again.
Here’s where the two actually differ for someone who just got a no.
You can get into Horizon. About 26% of applicants are admitted, out of up to 200 students a year. Still selective, and lots of people don’t get in, but it’s not twelve seats. If you’re shortlisted you’ll do a 30 minute interview. The admissions committee wrote up what they look for, and if you’re feeling written off right now, read about students who got in off the waitlist.
You leave with something. The whole program points at one thing: a capstone paper of about 5,000 words. Labs students get 15 one-on-one sessions with a PhD or post-doc, plus 4 with a writing coach and 4 with a publication specialist. Seminars run 20 instructor sessions in groups of 3 to 6, with the same writing and publication support. You keep all intellectual property and authorship rights. Labs students also get help through up to three rounds of journal submissions, though Horizon’s own page says straight out that it cannot and does not promise publication. That’s the honest line on something a journal decides, not a program.
You don’t have to move, or wait, or be 17. Clark runs once a year, in summer, in Lubbock, and you need to be 17 and free for seven weeks. Horizon Labs run year-round over 16 weeks, fully online. No flights, no housing, no June. The Winter 2026 cohort has a priority deadline of October 18, 2026, a final deadline of November 22, and starts December 14. If a seven week residential summer in Texas was never realistic for your family, this is the version that is.
The honest downsides. It’s $6,950, which is a real gap against a program that pays you $750 to show up. There’s need-based aid for households under $75,000, but Horizon calls that pool very competitive, so plan as if you won’t get it. Two scholarships exist: $695 for the top 25% of a cohort, $3,000 for the strongest application. And 8 to 10 hours a week on top of school is actual work, not a line you buy for your resume.
No prior research experience needed, which matters a lot if the hole in your Clark application was having nothing concrete to point at.
Apply to Horizon here. Priority deadline October 18.
Does a Clark Scholars rejection hurt your college applications?
No. Colleges never find out. There’s no box on the Common App for program rejections, no shared database of summer decisions, and no admissions officer who’ll ever know you applied.
What they see is what you did instead. Someone turned down by Clark who spent the summer doing real research looks, on paper, exactly like someone who never applied and did the same thing. The rejection leaves no trace. The work does.
Which is the part worth sitting with. What you wanted from Clark was never the acceptance email. It was seven weeks of real research with a real mentor and something to show at the end. You can still get all three. Clark was just one way in, and it was twelve seats wide.
Can you just research on your own?
Yes, and if cost is the blocker, this is your route.
You’ll be finding your own mentor, which means emailing faculty at a nearby university with a short, specific note about their actual published work. Most won’t write back. Send a lot of them. You’ll also be teaching yourself method and academic writing, which is slower on your own but completely doable. Our guides on getting research opportunities in high school and publishing research in high school cover the how, and doing biology research in high school gets specific if that’s your field.
The catch is follow-through. Way more students start a solo project than finish one. Programs work because a deadline and someone expecting you on Thursday are what get papers written. If you know you’ll hold yourself to it, go for it. If you’ve got honest doubts, that structure is the thing you’d be paying for.
So what now?
You’ve got three real options, and only one of them involves waiting.
Apply again next year as a senior, with something finished to point at. Chase another free program and hope the seat count works out this time. Or start the research now and stop depending on anyone’s cohort size.
If it’s the third one, Horizon Labs start year-round, and you’ll finish with a paper that has your name on it. About 26% of applicants get in. The work is 8 to 10 hours a week for 16 weeks, one-on-one with a PhD or post-doc, and you keep every right to what you produce.
The Winter 2026 cohort closes to priority applicants on October 18 and starts December 14.

Frequently asked questions
Texas Tech doesn’t publish one. What’s public is that 12 students take part each summer, picked from a national and international pool of juniors and seniors. The real rate is clearly tiny, but there’s no official figure.
Twelve each summer, per Texas Tech’s own program page.
Yes. They take juniors and seniors, so a junior who gets turned down can come back as a senior.
Yes. Texas Tech lists a $750 tax-free stipend, with room and board included.
Yes. The program says international students are eligible and welcome.
You have to be 17 by the start date, and Texas Tech says there are no exceptions.
It’s usually mid-February. Check the official Texas Tech page for the current cycle, since their published dates sometimes lag.
Depends on what you want. For free in-person lab work, look at SIMR and RSI. For year-round starts, a 26% admit rate, and a finished paper, Horizon is built for exactly that.
Horizon students do 8 to 10 hours a week, at least 100 hours total, across 10 to 16 weeks. On your own, budget more. We break it down by how long it takes to write a research paper.
