If you’re a high schooler interested in science, technology, engineering, or math, a STEM internship can be one of the most best ways to use your summer vacation to explore your interests outside the classroom.
STEM internships for high school students can help you explore advanced academic interests, building practical skills, gaining experience and getting exposed to college-level research and professional environments. This real world experience can also help students learn and gain skills: both hard skills, like data analysis, lab techniques, coding, or technical writing; and soft skills, like presentation skills, collaboration, time management, critical thinking and leadership skills.
STEM internships for high school students can range from university-hosted research internships and government-sponsored lab programs to industry placements, nonprofit initiatives, and remote internship programs. Depending on the program, high school students may work on scientific research, engineering design, computer science projects, data analysis, public health studies, environmental science, or other hands-on STEM career fields.
A strong STEM internship can show that a student has demonstrated curiosity, initiative, technical ability, problem-solving skills, leadership skills and intellectual maturity, and experience that could be utilize to bolster a college application. For motivated high school students, STEM internships could be a great opportunity for those with interest to explore new frontiers of research, informing directions of study for the next generation of researchers.
This guide covers the 16 best STEM internships for high school students, featuring highly selective research internships, university-based lab programs, government and nonprofit opportunities, and faculty mentor-led experiences, along with key insights on how to evaluate programs and navigate the application process.
STEM programs for high school students generally fall into three structural types. Understanding the differences helps you read past marketing language, see how a program actually works, and direct students toward opportunities with real structure, mentorship, and academic value.
While this is a brief introduction to the different program types, we encourage you to look at our in-depth analysis on these program types, which includes the “pros and cons” of each, as well as a list of programs that fall within them.
The best STEM internships and research programs are usually university-driven because their institutionally defined standards and oversight help guarantee a rigorous academic experience for all who participate. There are also select non-profit opportunities that provide analogous experiences, especially when they offer the highest quality of mentorship, a high degree of student agency, and/or clearly defined academic outcomes.
The programs below represent the top echelon of STEM internship or internship-like programs. These experiences were selected with the following criteria:
RSI is one of the most prestigious STEM research programs available, combining advanced coursework with mentored original research in science, mathematics, and engineering. You will need exceptional academic preparation and strong research potential to qualify. Because RSI is fully funded and admits only a very small cohort each year, it is both highly accessible financially and extraordinarily competitive academically.
SIMR is one of the strongest biomedical internships available, especially if you’re interested in biology, medicine, bioengineering, genetics, immunology, cancer biology, neuroscience, or any related fields. High school students work on medically oriented research projects under the guidance of Stanford faculty, postdoctoral fellows, students, and researchers. Because the program is commuter-only and housing is not provided, it’s most practical if you already have a reliable place to stay near Stanford.
If you would like to learn more about the SMIR internship program, you can check out our comprehensive guide to the program here.
Pioneer Research Institute gives you the opportunity to do original research online under the guidance of university professors, making it a strong fit for students who want a structured alternative to a traditional in-person STEM internship. Students can pursue research in fields such as computer science, artificial intelligence, mathematics, engineering, biology, physics, economics, and other STEM-related disciplines, depending on mentor availability.
If you want a rigorous, credit-bearing research experience with a substantial final paper rather than a short-term lab placement or observational internship, this might be a good choice. Pioneer Academics also offers need-based scholarships for high school students.
You can learn more about the Pioneer Research Institute in our comprehensive program guide to Pioneer Academics here.
The Simons Summer Research Program is a strong match if you want a serious, hands-on research apprenticeship in science, mathematics, or engineering before college. Simons places students with faculty mentors and active research groups so you can have exposure to how university-level research is actually done. Applicants must be nominated by their high school and the program is highly selective.
If you would like to learn more about the Simons Research Internship Program, you can check out our full guide to the program here.
The Anson L. Clark Scholars Program is one of the most selective programs in the US, offering a small cohort of students the chance to work closely with Texas Tech faculty on college-level research. It’s great for students who want a fully residential experience across STEM and selected non-STEM fields, rather than a classroom-based summer program. Because only around a dozen students are admitted each year, successful applicants typically need exceptional academic preparation, strong essays, and a clear fit with the available disciplines.

The Hutton Junior Fisheries Biology Program is for students interested in marine biology, freshwater ecology, fisheries science, environmental science, conservation, or natural resource management. Hutton matches students with local fisheries professionals, making the experience more geographically accessible for students who can commute to a nearby placement. Students who want field-based experience rather than a classroom-based summer program or purely virtual STEM project would find this particularly useful.
The Jackson Laboratory Summer Student Program is great for students interested in genetics, genomics, molecular biology, computational biology, biomedical science, or related research fields. Students join active research programs under scientific mentors, develop an independent project, and present their findings at the end of the summer.
Because it is fully funded and open to both graduating seniors and undergraduates, you should be prepared to show strong academic maturity, research motivation, and readiness for a full-time laboratory environment.
NIH SIP is a strong federal research opportunity for students interested in biomedical science, environmental health, public health, behavioral science, bioinformatics, engineering, computer science, mathematics, or other health-related fields.
Selection depends heavily on mentor availability and fit with individual NIH labs or institutes. The eligibility rules for high schoolers are narrower than many summer STEM programs, so it is best suited for graduating seniors who can commit to a full-time, in-person research position.
To learn more about the NIH Summer Internship program, including application information and thoughts on whether it is worth it, we encourage you to check out our full guide to the program here.
The AFRL Scholars Program is a strong fit for students interested in aerospace engineering, computer science, physics, materials science, cybersecurity, robotics, space systems, sensors, or other defense-related STEM fields. These programs are tied to specific research sites and defense-related projects, so students should review location-specific requirements carefully before applying.
NASA Office of STEM Engagement internships give high school students the chance to contribute to real NASA projects in areas such as aerospace engineering, robotics, computer science, data analysis, Earth science, space science, mission operations, and technical communications.
Be careful: NASA’s current central internship FAQ emphasizes college-level eligibility, while some STEM Gateway listings may include pre-college opportunities. Students should therefore search NASA STEM Gateway directly for high school-eligible projects rather than assuming that every OSTEM internship is open.
Meta Summer Academy is specifically for local Bay Area students who want early exposure to the technology industry without needing prior coding or professional experience. It’s not a traditional research internship. The program focuses on career exploration, mentorship, workplace skills, and hands-on learning in a corporate technology environment. Eligibility is limited to specific local communities, so it’s more of a targeted access program than a broadly available STEM internship.
MIT PRIMES is one of the most rigorous math-focused research opportunities available to high school students, especially those prepared for proof-based work, advanced mathematical reading, and sustained mentor-guided research. This is geared for sophomores and juniors who already have substantial mathematical maturity, with MIT noting that preferred applicants may have experience such as USAMO/USAJMO qualification, a college-level proof-based math course, or a major summer math program.
Because PRIMES is a year-round program rather than a short summer internship, students should be prepared for a significant long-term commitment. For more, please find our full participation guide here.
ASSIP gives undergraduate and high school students the chance to work one-on-one with faculty researchers on hypothesis-driven projects in fields such as biology, chemistry, neuroscience, computer science, engineering, environmental science, and related STEM areas.
Its flexible in-person, hybrid, and virtual formats make it more accessible than many residential lab programs, while the college-credit structure provides students with a formal academic outcome from the experience.

Lockheed Martin’s High School Internship Program is perfect for high school students interested in aerospace, defense technology, engineering, manufacturing, cybersecurity, software, or applied STEM careers. This is a corporate workplace experience where students may receive on-the-job training, mentoring, leader shadowing, professional development, facility tours, and exposure to real technical teams. Students should search current Lockheed Martin high school postings and confirm eligibility.
The HOPP Summer Student Program is one of the strongest biomedical research internships for high school students interested in cancer biology, oncology, computational biology, genetics, immunology, or translational medicine. Students are placed in MSK research labs and work with mentors on biomedical or computational projects.
Fred Hutch SHIP is great for rising seniors in the Seattle area interested in biomedical research, cancer biology, laboratory science, data science, or related health fields. The program begins with two weeks of hands-on laboratory safety and technique training, followed by six weeks in a Fred Hutch research group, giving students both structured preparation and direct exposure to mentored research.
You can find STEM internships for high school students by applying to structured programs or by contacting local labs, universities, hospitals, companies, and research centers directly. Structured programs usually have formal applications, deadlines, eligibility requirements, essays, transcripts, and mentor-matching processes, while independent opportunities often require students to email professors or STEM professionals with a short resume and a clear explanation of their interests.
To improve their chances, students should start early, apply broadly, and tailor each application to the specific research area or STEM field involved. For formal programs, structured personal essays can help students explain why they are interested in the opportunity, what skills or coursework have prepared them, and what they hope to learn. Letters of recommendation should usually come from math, science, or STEM-related teachers who can speak directly to the student’s academic ability, curiosity, work ethic, and readiness for challenging research or technical work.
Cold outreach can also help students find local or remote high school internships, especially when they are interested in computational research, data science, coding, software engineering design, or other projects that do not require daily access to a physical lab. Because many professors and professionals may not respond or may not have space for a high school intern, students should expect to contact multiple potential mentors, and in some cases 50 or more, while keeping each email concise, specific, and respectful.
High school students should usually start looking for summer STEM internships in early fall. Many selective programs open applications in November or December, with deadlines often falling between January and March, months before the school year ends.
Starting early gives students time to compare programs, check eligibility rules, prepare a resume, request recommendations, gather transcripts, and complete essays or short-answer questions. Some local internships or mentor-based opportunities may appear later, but students targeting competitive research programs should not wait until spring to begin.
STEM internships can strengthen college applications when they show real academic curiosity, initiative, and the ability to work on challenging problems beyond the classroom. Selective programs, lab placements, and research internships may help students demonstrate that they have explored a STEM field seriously, especially when the experience connects clearly to their coursework, intended major, or long-term interests.
The most meaningful internships usually provide students with something specific to discuss in their applications, such as a research question they investigated, data they analyzed, or a technical skill they learned. A STEM internship does not guarantee admission to a selective college, but it can become a strong part of an application when the student can explain what they contributed, what they learned, and why the experience shaped their academic direction.
Yes, there are remote and virtual internships available for high school students, especially in fields that can be done with a computer. These opportunities may include online research programs, virtual mentorships, coding internships, computational projects, or structured programs where remote interns work with a mentor and complete a final project or research paper.
Students, however, should evaluate any online internship carefully by looking at the quality of mentorship, the structure of the project, the expected time commitment, and whether the program produces a meaningful final outcome.
Yes, 9th and 10th graders can sometimes find STEM internships or research-style programs, but their options are usually more limited than those available to juniors and seniors. Many university labs, hospital programs, and wet-lab internships require students to be at least 16 or 17 because of safety, supervision, liability, and lab access rules.
Younger high school students may have better luck with virtual research programs, coding or data science projects, university enrichment programs, science fairs, nonprofit STEM programs, or project-based mentorships that do not require access to a physical lab.
Choosing the “best” STEM internship depends on your interests, eligibility, location, career goals, and readiness for independent work. If you want a full-time research experience, programs like RSI, Simons, JAX, Fred Hutch, MSK, and NIH can offer serious exposure to university, hospital, or laboratory-based STEM research. If you want to explore careers in aerospace, engineering, technology, or applied science, check out opportunities through NASA, AFRL, Lockheed Martin, Meta, local businesses, or other government and industry programs. These can help students gain job experience and better understand future employment opportunities.
For students who want a structured research experience with more control over the direction of their work, Pioneer Academics can also be a strong option, especially for those who need a flexible online format.
