Summary
The five main STEM research competitions for US students are ISEF, the Regeneron Science Talent Search, the Davidson Fellows Scholarship, the Thermo Fisher Junior Innovators Challenge, and the 3M Young Scientist Challenge. ISEF and STS carry the most weight with top universities. The right one for you depends on your grade, whether you have completed original research, and whether you want to present at a fair or submit finished work.
If you're aiming to study science at an Ivy League school, STEM research competitions are an important step. They show universities that you have the research, problem-solving, and critical thinking skills you need to be a successful scientist.
In this guide, you'll get the advice of our ScienceFair mentors, who are past ISEF finalists, award winners, STS Scholars, and Davidson Fellows Laureates.

Regeneron International Science and Engineering Fair (ISEF)
ISEF is the world's largest and most prestigious pre-college science fair, where students advance through regional and state competitions before reaching the international stage. Often called the "Olympics of science fairs," it draws roughly 1,700 finalists from 60+ countries each year, who compete across 22 categories for more than $7 million in awards.
It is best for motivated high schoolers (grades 9-12) with an original research project and the confidence to present and defend their work in front of judges. It rewards depth over breadth, so it suits students genuinely curious about one problem that fills a real niche within a bigger world issue.
Beyond cash awards, ISEF is widely recognized by top universities and builds real research, presentation, and problem-solving skills that carry into college and beyond. You'll get the most out of ISEF if you compete across multiple years or publish your project in a journal.
Regeneron Science Talent Search (STS)
STS is a national competition, open only to US high school seniors who have completed an independent research project. Applicants advance through tiers, with the Top 40 traveling to Washington, D.C. to present their work and compete for prizes up to $250,000.
It's the ideal competition for students who have spent two or three years working on a single, original project. Since the application looks at the whole student the way a college application does, it is important to back up your research with strong grades, test scores, activities, and recommendations. The catch is timing: because it happens in senior fall, STS won't appear on your college applications. But those who do well are typically already on track for schools like MIT, Stanford, and the Ivies, and the recognition, network, and skill of distilling years of research into a tight 20-page paper open real doors in STEM.
The STS timing catch
STS runs in senior fall, so results land after early applications are in and won't appear on your Common App. Enter it for the research discipline, the network, and the scholarship money, and let ISEF carry the application-year signal.
Davidson Fellows Scholarship
The Davidson Fellows Scholarship awards US students under 18 college scholarships of $100,000, $50,000, and $25,000 for a completed "significant piece of work." Unlike most competitions on this list, it isn't science-only. Alongside STEM categories, there are tracks for literature, music, philosophy, and an "outside the box" option, though the common thread is deep, years-long work with real impact.
The scholarship rewards students who have already made a meaningful contribution to their field, so it is usually for students whose research is fully developed, rather than students who are just starting out. What sets it apart is the money itself. The awards must go toward an accredited college, and the $100,000 top award makes it the most valuable pure scholarship in the field. Beyond the funding, winners join a well-connected alumni network and often present their work on national news.
Thermo Fisher Junior Innovators Challenge
The Junior Innovators Challenge is the premier national STEM research competition for US students in grades 6-8. It starts at local affiliated science fairs, where the top 10% of competitors are nominated to the challenge. The top 300 are named Innovators nationally, and 30 finalists travel to Washington, D.C., where they compete for awards up to $25,000.
No experience is needed to enter. You just need a topic you're genuinely curious about to research, which makes it the natural first competition for younger students testing whether research is for them, either solo or in teams of up to three.
On its own, it won't move the needle with colleges given how young competitors are. JIC is a stepping stone that builds real research and communication skills and sets students up for ISEF, STS, and the competitions that admissions officers do value.
3M Young Scientist Challenge
The 3M Young Scientist Challenge is the most prestigious middle school science competition in the US, open to students in grades 5-8. Each student submits a short video pitching an invention that solves an everyday problem affecting them, their family, or their community. Then the ten finalists spend a summer working one-on-one with 3M scientists before competing for $25,000 and the title of "America's Top Young Scientist."
What sets YSC apart is that it rewards inventing over researching: you're judged on a creative solution and how well you pitch it on camera rather than on a lab write-up, so communication counts from the very first submission. That makes it a natural fit for hands-on 10-to-14-year-olds who like building things and explaining their ideas.
Since it's individual-only with no experience required, it's one of the most accessible ways for a younger student to test-drive independent science before moving toward research-heavy competitions like JIC and ISEF.
How to choose the right competition for you
To choose the right competition, be clear about eligibility, your research experience, your time frame, and what you're aiming for.
• ISEF requires you to be in grades 9-12 with a research project completed in the past 12 months. It's ideal if you have a clearly defined project and want to stand out to universities, meet like-minded students, and compete at the international level.
• STS is only open to high school seniors in the USA or American citizens living abroad. Students normally apply with projects developed over several years, sometimes published. The application is intense and time-consuming, so it suits students who want to engage with their research on a deeper level and potentially win financial awards that help with university.
• The Davidson Fellows Scholarship is open to US citizens or permanent residents aged 18 or younger, across several categories beyond STEM, and you can apply in pairs. It requires a significant piece of work that has been tested or proven. It's similar to STS, but there is no final competition element, and you win a scholarship rather than prize money.
• JIC is for students in 6th-8th grade in the USA. It's a strong choice for younger students who want to do research, engage with science, and compete for up to $25,000. Many go on to high school STEM competitions.
• YSC is for students in 5th-8th grade who are legal US residents. Unlike JIC, it focuses on creating an invention or solution to an everyday problem that affects you, your family, or your community. Finalists then join a mentorship program with a 3M scientist before presenting their solution to win up to $25,000. It rewards communication and suits curious young scientists.
How colleges view STEM research competitions
Penn's admissions dean reported that nearly a third of students admitted to the Class of 2026 did academic research in high school, and Yale and Columbia both give applicants a dedicated place to submit research: Yale through its optional STEM research supplement, and Columbia through an optional research section in its application. T20 schools take research seriously.

What STEM competitions add is external validation: independent judges have evaluated your work, and even if you haven't won an award, that carries weight in your college applications.
It is especially valuable when the competition is a high school one, such as ISEF or STS. If you just did JIC or YSC in middle school, and then didn't continue to do research, compete, or publish a paper in high school, it won't be impressive.
Three common misconceptions about STEM competitions
You need expensive equipment
You don't need cutting-edge technology or lab equipment to win an award at ISEF or other STEM research competitions. Winning projects do well because they show originality and critical thinking and are clearly explained. Simple projects done at home or in a school lab are just as likely to win as complex ones when they show those markers.
Not winning an award is failing
Reaching any of the competitions in this article is impressive. Making it to ISEF means being one of roughly 1,700 finalists drawn from the millions of students who compete in affiliated fairs worldwide. Reaching the Top 300 at STS is already an incredible achievement. You don't need an award to stand out, and admissions officers agree, so include these achievements in the relevant section of your Common App.
STEM competitions guarantee Ivy League admission
Nothing can guarantee admission to a T20 school. STEM research competitions show that you have valuable skills and the potential to be a great scientist, and the way you present your achievements makes a real difference. Poor framing can make a national or international honor sound forgettable, so order your science fair wins from most to least important so that your accomplishments are clear.
How to build a project that competes and wins
Every competition on this list rewards the same thing underneath: original research, done thoroughly and explained clearly. Getting there takes more than a good idea; it takes a clear research plan from the start, the discipline to see it through alongside school, and the ability to defend your work when a judge starts asking hard questions.
That's where Crimson's partnership with ScienceFair comes in. ScienceFair's mentors have competed in and won these exact competitions, as ISEF Grand Award winners, STS finalists, and Davidson Fellows Laureates, so they know what separates a strong project from a winning one. They'll help you sharpen your research question, build a project that stands out, and walk into your judging Q&A ready for anything. And through Crimson's Ivy League research mentors, you'll have expert guidance to shape your work from the first question to the final presentation.
Frequently asked questions
Which STEM competition is most prestigious for high school students?
ISEF and the Regeneron Science Talent Search are the two most prestigious STEM competitions for high school students.
What grade should my child start competing?
There are national STEM competitions for students from 5th grade all the way to the last year of high school. The 3M Young Scientist Challenge is open to students in grades 5-8, then the Junior Innovators Challenge is for students in grades 6-8. Students can compete at ISEF in grades 9-12, and STS is open to high school seniors only.
Do STEM research competitions actually help with college admissions?
Yes. Penn's admissions dean reported that nearly a third of admitted students did research in high school, and schools like Yale and Columbia invite research submissions in their applications. Competitions give that research external validation from independent judges, which helps you stand out. Research strengthens college applications, but it doesn't guarantee a spot.
Are these competitions open to international students?
ISEF is an international competition, and you should check if your country has an affiliated fair. There are also other STEM competitions, including the S.T. Yau High School Science Award, EUCYS, Stockholm Junior Water Prize, BT Young Scientist, I-SWEEEP, and Genius Olympiad.
Do I need original research or a finished project to enter?
Depending on the competition, you may need original research to enter. ISEF and JIC need a research project, STS needs a completed independent paper, Davidson needs finished work, and 3M needs only an invention idea on video.
Can I enter more than one competition?
Yes, many students participate in different competitions over time, and one research project can be submitted to multiple competitions.
For instance, ScienceFair's founder, Rishab Jain, was named America's Top Young Scientist after winning the 3M Young Scientist Challenge. He then participated in Broadcom MASTERS (now the Thermo Fisher Junior Innovators Challenge). After that, he qualified for ISEF three times, winning awards three times. He also published his research, participated in RSI, won JSHS twice, and became a Coca-Cola Scholar.
How much does it cost to enter these competitions?
Entering all the competitions in this list is free, and the competitions pay for your travel to their finals. The real investment is your time to do the research well, plus any equipment your project may need.
Do you need a mentor or a university lab to win?
Some competitions, such as ISEF, require you to have an unpaid mentor to compete, such as a teacher or parent who can sign off on key paperwork. You don't need a lab or a lab-based project to win. However, many students do have extra guidance from research experts to support them. ScienceFair can provide that expert advice.
