All Online Summer Internships for High School Students in 2026

Here’s everything worth applying to, grouped by subject. Pick yours and scroll down for details:

Coding & Tech Programs

If you want to build apps, write code, or learn AI, these four programs are the best online options in 2026. All of them are free except for the basic Forage certificates, which are also free.

Kode With Klossy is a free 2-week coding camp for girls and gender-expansive teens ages 13-18. Three tracks are offered in 2026: Web Development, Machine Learning, and Data Science.

Camps run virtually and in-person in June, July, and August. The program is a 501(c)(3) nonprofit founded by Karlie Kloss and headquartered in NYC.

Girls Who Code Pathways is a free, flexible, fully virtual summer program for high school girls and non-binary students.

The 2026 curriculum focuses on AI, coding, and building tech for social good. Applications usually open in early spring. No prior coding experience is required.

Code in Place is Stanford’s free 5-week introduction to computer science. You work through the same CS106A content as Stanford undergrads, with a volunteer section leader helping a small group.

Applications open in March or April each year. Perfect if you’ve never coded before.

Forage offers free virtual job simulations from tech companies including Deloitte (STEM track), Goldman Sachs (engineering), and Accenture.

Each simulation takes 5-7 hours, requires no application, and gives you a certificate. Do 2-3 to explore tech careers in different industries.

Research Programs

These are competitive academic research internships with real faculty supervision. Acceptance rates are low, but the credentials carry real weight for college applications. Most pay a stipend or are free.

Johns Hopkins Brain Sciences Internship (Remote) is a 5-week nationwide remote research program. You work with Hopkins neuroscientists on brain-related projects. The program includes stipends. Applications typically open in January with a March deadline.

Stanford AIMI Summer Research is for students interested in artificial intelligence in medical imaging. You work alongside Stanford researchers and clinicians on AI/ML projects.

Remote options available. Paid. Very competitive, so a strong math and coding background helps.

NASA SEES (STEM Enhancement in Earth Science) is nationwide, free, and one of the strongest free research programs available.

You analyze NASA data on projects ranging from astrophysics to climate. Must be 16 by July 5, 2026, US citizen. The 2026 deadline is February 22.

Smithsonian Virtual High School Internships places students remotely with various Smithsonian museums and research units over 8 weeks.

Projects include digitizing historical collections, supporting education programs, and research writing. Unpaid but highly respected.

ASSIP at George Mason University is an 8-week research mentorship with university faculty across sciences. Stipends vary by track.

Remote options have expanded since 2023. Applications typically open in December with a February deadline.

If you're specifically interested in aerospace and space science, our aerospace engineering summer internships for high school students guide walks NASA HAS, SEES, AFRL Scholars, and Beaver Works in depth.

A note on Simons Summer Research at Stony Brook: it’s a strong program, but the 2026 application cycle has already closed. Juniors interested should plan for the 2027 cycle opening in fall 2026.

Writing & Editorial Programs

If your thing is writing, journalism, or publishing, these four programs offer real mentorship and portfolio-building opportunities. Two are free, one is paid, and one depends on the cycle.

The Adroit Journal Summer Mentorship is a free online program that pairs established writers with high school students.

The 2026 program accepts poetry, fiction, and creative nonfiction tracks. Graduating seniors and gap year students are eligible. This is one of the most respected free writing mentorships in the country.

Project Write Now (PWN) Teen Internship is for ages 15-18 and offers hands-on summer experience in education, publishing, or journalism.

Roles include teaching assistant, editorial assistant, and interview projects. Applications for 2026 open in February. The program runs through summer.

Macmillan Publishers Summer Internship is a paid, full-time remote program for summer 2026. Placements are in editorial, marketing, and publishing operations.

Typically college-level, but exceptional rising high school seniors occasionally break through. Applications open in winter.

EnergyMag Research Internship combines writing with renewable energy research. Part-time virtual roles run 2-8 weeks. You produce published articles on emerging technologies. Unpaid but gives you real publication credits on a real industry website.

Business & Finance Programs

For students interested in finance, consulting, entrepreneurship, or startup work, these options range from completely free simulations to paid placement programs. Start with the free ones.

Forage has multiple Forage finance simulations from JPMorgan (Investment Banking), Goldman Sachs, BNY Mellon, and Citi. Each is free, takes 5-7 hours, and results in a certificate. Complete 2-3 across different firms to explore finance before committing to a paid program.

Polygence is a research mentorship program founded by Stanford and MIT scholars. You work one-on-one with a mentor from a network of 2,000+ across 40+ fields.

Programs start at $495 for Pods (group format) or $3,000+ for individual mentorship. Not an internship in the traditional sense, but legitimate structured research.

Lumiere Education offers a similar research mentorship model with focus on publication outcomes. Pricing is in the same $2,500-4,500 range. Mentors include Harvard, Stanford, and other top-school PhDs. Rolling applications.

Pioneer Academics is more expensive than Polygence or Lumiere and more research-focused. It offers college credit in some cases. Typically runs $6,000+ and is the most prestigious of the paid research programs. Competitive admissions.

Ladder Internships matches students with startup projects for 8 weeks virtually at 10-15 hours/week. The 2026 summer cohort deadline is May 10.

Costs run $2,990 for basic placement to $7,400 for the combination program. No stipend, you pay them. Financial aid is available for families earning under roughly $50,000.

If creative fields like fashion or design interest you more than finance, our fashion internships for high school students guide covers pre-college programs at Parsons, Pratt, RISD, and the Condé Nast Summer Internship.

Build Your Own Online Internship

A real option that’s often better than paid placement programs: create your own. You can learn more, build a stronger resume, and spend $0 if you use the right free tools.

• Code an app or website that solves a problem in your school or community. Push it to GitHub. Write about your process on a blog.

• Start a YouTube channel or podcast focused on a niche you love. Fashion, coding tutorials, college prep advice, whatever. Show consistent work.

• Freelance on Fiverr or Upwork doing logo design, tutoring, writing, or translation. You’ll learn client communication and earn real money.

• Write for your school newspaper or start one. Pitch articles to Teen Vogue, Medium, or a local paper. Published writing is valuable.

• Email university professors whose research interests you. Many accept unpaid high school volunteers for data entry, literature review, or basic lab work. Cold outreach works more than you’d expect.

• Build a portfolio on Behance or Dribbble if you’re into design. Document your creative work publicly.

For students aimed at medicine or dermatology specifically, our dermatology internships for high school students guide covers the AAD Pathways program, NIH opportunities, and how to find a local dermatologist to shadow.

How to Apply to Competitive Programs

Johns Hopkins BSI, Stanford AIMI, NASA SEES, Smithsonian, and Adroit Journal have similar application pieces. Here’s what you’ll need:

• 1. Transcript: your current high school transcript, usually sent by your counselor.

• 2. Essays or personal statement: 250-500 words on why this specific program, your prior interests, and your goals.

• 3. Teacher recommendation: one or two letters. For research programs, science or math teachers. For writing programs, English or humanities teachers.

• 4. Standardized test scores (sometimes): SAT or ACT scores if available. Several programs are test-optional.

• 5. Writing sample (writing programs only): 1-2 polished pieces in the genre you’re applying to (poem, short story, article).

• 6. Portfolio (creative programs only): for Adroit Journal, your strongest 3-5 creative works.

When to Apply

Most summer 2026 programs open applications between December 2025 and April 2026. Here’s the timing:

How to Stand Out in Applications

Competitive programs get dozens of applicants for every spot. What makes your application memorable:

• Show prior exploration. Complete 2-3 Forage simulations in your field before applying. Mention them in your essay. It shows you’re committed.

• Write specific essays for each program. Mention the specific lab at Johns Hopkins, the Stanford AIMI project, or the Smithsonian department you’re targeting. Generic essays get rejected.

• Request recommendations 3-4 weeks early. Provide your teacher with your resume, your essay draft, and the program’s focus. They write stronger letters when they have context.

• Follow up respectfully. A short email 10-14 days after submission thanking the coordinator and confirming materials received shows you’re organized.

Frequently Asked Questions

What’s the best free online internship for a 10th grader?

Forage for general exploration. Kode With Klossy, Girls Who Code, or Code in Place for coding interest. Most other programs require juniors or seniors.

Are paid programs like Polygence or Ladder worth the money?

Depends on your family’s financial situation and what you need. For students who can’t get into free competitive programs and whose families can afford it, they provide structure and references. For most students, free programs offer better value.

How many online internships should I do?

One substantive program per summer (Johns Hopkins BSI, Stanford AIMI, or equivalent) plus 2-3 free Forage simulations is the sweet spot. More than that dilutes your focus.

Do colleges care about Forage certificates?

Somewhat. They recognize Forage as career exploration, not deep work experience. Use them as supporting evidence alongside real research or volunteer experience.

What if I haven’t taken AP Computer Science or other prerequisites?

Most programs don’t require prerequisites. Code in Place specifically teaches beginners. Kode With Klossy has no coding background requirement. Research programs teach you what you need in the first week.

Final Word

Online summer internships for high school students really do exist in every major field, though quality varies hugely. Free programs like Kode With Klossy, Girls Who Code, Johns Hopkins BSI, NASA SEES, and the Adroit Journal offer real value without cost.

The best moves: pick the subject area you love, apply to 2-3 free competitive programs, add 2-3 Forage simulations, and spend summer learning deeply in one.
