High School Internships That Actually Impress Colleges: NASA, Palantir & More

The most prestigious high school internships — NASA OSTEM, Palantir, and RSI — accept just 2% to 10% of applicants, making them more selective than many elite colleges. When most students think about internships, they picture college juniors fetching coffee. But a growing number of high-profile organizations now offer structured internship and research programs specifically for high school students, and admissions officers at top colleges have taken notice. A legitimate internship at NASA, Palantir, or a Department of Defense lab tells a selection committee something no AP score ever could: this student can contribute to real work in a professional setting.

This guide covers the high school internships that genuinely move the needle on college applications in 2026. We break down what each program involves, how competitive it is, when to apply, and what it signals to admissions officers. Whether you are a rising sophomore exploring STEM or a junior looking to stand out before early decision applications, this is your roadmap to the internships that matter most.

Why High School Internships Matter for College Admissions

College admissions officers evaluate applicants on the depth and authenticity of their engagement outside the classroom. An internship at a recognized institution demonstrates initiative, professional maturity, and the ability to apply academic knowledge in a real-world context. These qualities are difficult to demonstrate through coursework or standardized tests alone.

Tier 1: The Most Competitive and Impressive High School Internships

These programs are nationally recognized, highly selective, and carry significant weight in college applications. They typically involve real research or project work alongside professionals and often come with stipends or full funding.

NASA OSTEM (Office of STEM Engagement) Internships

NASA offers paid internships to high school students (16 and older) through its Office of STEM Engagement. Interns work at NASA centers across the country, including the Jet Propulsion Laboratory, Kennedy Space Center, and Goddard Space Flight Center, on projects ranging from aerospace engineering to data science and environmental research. The application process is centralized through NASA’s OSTEM portal, and placements are highly competitive. NASA does not publish exact acceptance rates for high school applicants, but the overall OSTEM internship acceptance rate across all levels is estimated at roughly 10% to 15%. Internships typically run for 10 to 16 weeks during the summer, and students receive a stipend. Applications usually open in early fall for the following summer. The NASA name on a resume is one of the strongest signals a high school student can send to admissions committees, particularly for STEM-focused applicants.

Palantir High School Internship (Launch Program)

Palantir Technologies, the data analytics and defense technology company, runs a selective internship program that occasionally includes high school students through its Launch initiative and related programs. Palantir internships focus on software engineering, data analysis, and product development. The program is based in Palo Alto and other Palantir offices. Acceptance rates are not publicly disclosed, but given the company’s selectivity at the college level (where acceptance rates hover around 1% to 2%), the high school pathway is extraordinarily competitive. Students who land a Palantir internship typically have strong coding backgrounds and demonstrable project portfolios. Applications open on Palantir’s careers page, and networking through hackathons and coding competitions can help students get noticed. For students interested in technology and defense applications, a Palantir internship is among the most impressive credentials a high school student can earn.

AEOP (Army Educational Outreach Program) Internships

The Army Educational Outreach Program is one of the largest and most accessible pipelines to legitimate STEM research for high school students. AEOP runs several programs, including UNITE (a summer STEM enrichment program), the Research and Engineering Apprenticeship Program (REAP), and the High School Apprenticeship Program. REAP places students in research positions at universities and Army research labs, where they work alongside scientists and engineers on real projects. The apprenticeship is paid, typically providing a stipend of $2,000 to $3,000 for the summer. AEOP programs collectively accept several hundred high school students per year across the country. The application process is centralized through the AEOP website, with deadlines typically in February or March. AEOP programs are particularly valuable because they provide genuine research experience, often leading to co-authored publications or conference presentations. Admissions officers at top STEM programs recognize AEOP as a credible and competitive credential.

NIH High School Scientific Training and Enrichment Program (NIH SIP)

The National Institutes of Health Summer Internship Program places high school students (ages 17 and up) in research laboratories at the NIH campus in Bethesda, Maryland. Interns work directly with NIH scientists on biomedical research projects spanning cancer biology, neuroscience, genomics, and public health. The program runs for eight weeks during the summer and provides a stipend. Acceptance is competitive, with approximately 15% to 20% of applicants receiving offers. The NIH name carries enormous weight in college admissions, particularly for students applying to pre-medical, biology, and public health programs. Applications open in November with a March deadline. Students who complete the program often co-author research papers and present at the NIH poster day, both of which are strong additions to college applications.

Brookhaven National Laboratory High School Research Program

Brookhaven National Laboratory on Long Island runs a competitive summer research program for high school students. Participants spend several weeks working in one of Brookhaven’s research departments, which include physics, chemistry, biology, and environmental science. The program provides a stipend and offers students the chance to work with cutting-edge equipment and collaborate with professional researchers. Brookhaven accepts a limited number of high school students each year, and the program is most accessible to students in the New York metropolitan area, though national applicants are also considered. Applications typically open in winter with a spring deadline.

Tier 2: Highly Respected Internship and Research Programs

These programs are well-known within their respective fields and carry real weight in college applications. They may be slightly less selective than Tier 1 or focused on a specific geographic area, but they still represent exceptional opportunities.

SYEP (Summer Youth Employment Program) and Government Internships

The Summer Youth Employment Program is the largest youth employment initiative in the United States, operated primarily in New York City. SYEP places young people ages 14 to 24 in paid internships across city agencies, nonprofits, hospitals, and private companies for six weeks during the summer. While SYEP is not as selective as NASA or NIH programs, the sheer scale of the program means placements range widely in quality. The most impressive SYEP placements include positions at city government offices, research hospitals, and technology organizations. SYEP uses a lottery system with roughly 75,000 to 100,000 participants selected from over 150,000 applicants each year. Applications open in spring. For college applications, an SYEP placement is most valuable when the student can articulate what they learned and how they contributed meaningfully to their host organization. Similar municipal youth employment programs exist in Boston, Chicago, Los Angeles, and other cities.

MITES (MIT Introduction to Technology, Engineering, and Science)

While MITES is technically a summer program rather than an internship, it deserves mention here because of its strong research and project components. MITES places students in an intensive six-week experience at MIT that includes hands-on engineering projects and exposure to working laboratories. The program is completely free and has an acceptance rate of approximately 5% to 8%. For a detailed breakdown of MITES and similar programs, see our guide to the most prestigious summer programs for high school students.

Congressional Internships

Many members of Congress offer unpaid internships to high school students, particularly during the summer. Interns typically work in the member’s district office or Washington, D.C. office, handling constituent correspondence, attending hearings, and assisting with research. The competitiveness varies by office, but securing a congressional internship demonstrates initiative and interest in public service. These internships are especially valuable for students interested in political science, law, and public policy. To apply, contact your local representative or senator’s office directly, as most do not centralize applications. Students who are most successful at landing these positions often have strong writing samples and prior involvement in student government, debate, or community service.

Microsoft High School Internship and TEALS Program

Microsoft offers limited high school internship opportunities, primarily through its Explore and TEALS (Technology Education and Literacy in Schools) initiatives. While the formal high school internship track is extremely competitive and not always available, Microsoft’s TEALS program connects high school students with volunteer software engineers who co-teach computer science courses. Students who participate in TEALS-affiliated projects and demonstrate exceptional coding skills occasionally gain access to internship-like experiences with Microsoft mentors. The company’s main internship pipeline targets college students, but high school students with strong portfolios (competitive programming results, significant open-source contributions, or published apps) have occasionally been offered positions. Applications are posted on Microsoft’s careers page.

Fermilab Saturday Morning Physics and Internships

Fermi National Accelerator Laboratory near Chicago offers a Saturday Morning Physics program for high school students, and selected participants may be invited to summer internship opportunities in particle physics research. Fermilab also participates in the Department of Energy’s Science Undergraduate Laboratory Internships (SULI) program, which occasionally includes advanced high school students. Working at one of the world’s premier particle physics laboratories is a remarkable credential for any student interested in physics, and the program provides direct exposure to the kind of research environment students would encounter at top university physics departments.

Tier 3: Valuable Internships That Build Strong Profiles

These internships are accessible to a broader range of students and still add meaningful depth to college applications when framed properly.

Local University Research Assistantships

One of the most underrated paths to a genuine research internship is reaching out directly to professors at local universities. Many faculty members are willing to take on motivated high school students as research assistants, particularly in STEM fields. This approach requires initiative: students should identify professors whose work aligns with their interests, read one or two of their recent papers, and send a concise email explaining their background and enthusiasm. There is no centralized application, and “acceptance rates” do not apply in the traditional sense, but students who demonstrate genuine knowledge and willingness to commit time are often welcomed. These positions may be unpaid but can lead to co-authored publications, strong recommendation letters, and authentic research experience that rivals formal programs.

Hospital and Clinical Internships

Many hospitals offer volunteer and internship programs for high school students interested in healthcare. Programs at major academic medical centers (such as Johns Hopkins, Cleveland Clinic, and Mass General Hospital) are more competitive and carry more weight than general hospital volunteering. The most impressive clinical internships involve exposure to research, patient care observation, or administrative projects in specialized departments. While basic hospital volunteering is common among pre-medical applicants, a structured internship program with defined responsibilities stands out on applications.

Nonprofit and Social Impact Internships

Internships at established nonprofits and social impact organizations can be powerful additions to college applications, particularly for students interested in humanities, social sciences, and public policy. Organizations like the ACLU, local chapters of Habitat for Humanity, and community development corporations often welcome high school interns. The key is choosing organizations where you will do substantive work rather than administrative tasks. An internship where you helped draft policy briefs, organized community programs, or analyzed data for a nonprofit’s annual report tells a much stronger story than generic office assistance.

Startup Internships

Working at a startup can provide high school students with an unusually broad range of responsibilities and direct mentorship from founders. Because startups operate with small teams, interns often contribute meaningfully to product development, marketing, customer research, or engineering. The challenge is finding legitimate opportunities, as startup internships are rarely formalized. Platforms like LinkedIn, AngelList, and local startup incubators can help students identify opportunities. For college applications, a startup internship is most impressive when the student can describe specific contributions and measurable outcomes.

How to Land a Competitive High School Internship

Earning a spot in a top internship program requires more than good grades. Here is what the most successful applicants do differently.

Build a Portfolio Before You Apply

The strongest internship applicants do not wait until the application to start building their credentials. Students who land NASA, Palantir, or NIH internships typically have prior experience in relevant areas: science fair projects, independent research, competitive programming results, published writing, or meaningful community projects. Start building this portfolio as early as sophomore year so that by the time you apply, you have tangible evidence of your abilities and interests.

Write Application Materials That Show Specificity

Generic essays about “wanting to make a difference” will not get you into competitive programs. The best applications reference specific projects, research questions, or problems that excite the student. If you are applying to NASA, mention a particular mission or research area that fascinates you. If you are applying to NIH, discuss a specific disease mechanism or public health question. Selection committees want evidence that you understand what the organization does and can articulate why you belong there.

Leverage Your Network Ethically

Networking is a legitimate part of the professional world, and high school students should learn to do it well. Attending science fairs, hackathons, and academic conferences puts you in contact with researchers and professionals who may later become mentors or recommend you for opportunities. The key is authenticity: reach out because you are genuinely interested in someone’s work, not because you want a line on your resume. Teachers, guidance counselors, and family friends who work in relevant fields can also help you learn about opportunities you might not find on your own.

Apply Broadly and Have a Backup Plan

Given the competitiveness of top internships, applying to only one or two programs is risky. Create a tiered list of reach, target, and safety opportunities, similar to the approach you would use for college applications. If you do not land a formal internship, remember that self-directed projects, independent research, and community work can be equally impressive to admissions officers. What matters is how you use your time, not whether a specific institution’s name appears on your activity list.

What If You Do Not Get a Formal Internship?

Not landing a formal internship is completely normal and not a disadvantage in college admissions. Many students who gain admission to Ivy League and other highly selective schools never held a formal internship in high school. What matters is demonstrating initiative, depth, and genuine engagement with your interests.

Strong alternatives to formal internships include conducting independent research under a university professor’s guidance, launching an entrepreneurial or community project, attending a competitive summer program like those covered in our prestigious summer programs guide, getting a regular job that demonstrates responsibility and maturity, or pursuing intensive self-study in a field that excites you. Admissions officers at top colleges value authenticity and depth over brand names. A student who spent the summer building a meaningful community organization or conducting original research at a local lab can be just as competitive as one who interned at NASA.
