1. Ladder Internships

Dates: Fall cohorts run ~8 weeks; multiple start dates annually
Location: Virtual
Benefits: Unpaid internship

Ladder Internships is a world-class internship program designed for ambitious students who want a structured, meaningful experience during the school year. The program partners with top start-ups and NGOs, giving students the opportunity to contribute to real-world projects while learning professional communication, research, and project-management skills.

Fall internships for high school students offer three tracks:

  • The Startup Internship Program runs for eight weeks, includes weekly meetings with a company supervisor, and costs $2,990. It’s designed for students who want hands-on experience contributing to growth, product, marketing, research, or engineering initiatives inside active start-ups.
  • The CEO Internship Program, priced at $4,990, is built for highly driven students who want to work directly with a start-up CEO—often from a FAANG background. This track offers exceptional mentorship and exposure to strategic decision-making.
  • The Combination Program includes both the CEO internship and a mentored research track, offering dual experience for $7,400.

All tracks offer full financial aid for students with demonstrated need, and the program is selective, reviewing applications carefully to match students with the right placement. For students applying to the upcoming Winternship cycle, the application deadline is December 19, with the cohort beginning January 5.

2. Harvard–Smithsonian Science Research Mentoring Program (SRMP)

Dates: September 2025 – May 2026
Location: Cambridge, Massachusetts
Benefits: Paid internship; stipends provided by the City of Cambridge

The Harvard–Smithsonian SRMP is one of the most rigorous and respected school-year research internships available to high school students. Run by the Center for Astrophysics | Harvard & Smithsonian (CfA), the program pairs selected students with astrophysicists and data scientists.

Interns meet weekly, complete analysis assignments, and receive direct mentorship from CfA researchers. By the end of the program, each student develops a research poster and presents their work at a formal scientific symposium.

SRMP is free for participants and includes stipends funded by the City of Cambridge. Students must live in or attend school in Cambridge and demonstrate a strong interest and preparation in science and math. With its small cohort size and intensive research expectations, SRMP remains one of the most valuable STEM-focused academic-year opportunities available to high school students.

3. New York City Office of the Mayor Internship

Dates: Dates vary depending on internship type
Location: New York City
Benefits: Paid and unpaid internship (varies by role/agency)

The NYC Mayor’s Office offers a substantial school-year internship where students support departments ranging from digital strategy to community affairs, public health, operations, and sustainability.  

Interns work 10–15 hours per week on research, event coordination, communications support, and policy-adjacent tasks. They also attend professional development sessions and speaker events with city leaders.

The program is open to NYC high school students who are at least 16 and can balance weekly commitments. While exact acceptance numbers aren’t published, city internships naturally remain selective due to departmental capacity. For students exploring public service or policy, this is one of the most respected high school fall internships in government.

4. U.S. Senate Page Program

Dates: Dates vary
Location: Washington, D.C.
Benefits: Roughly $37,238 annualized (varies by senator)

The U.S. Senate Page Program is among the most historic and sought-after internships for high school students. Pages live in supervised residence halls, study at the Senate Page School, and work inside the Senate chamber supporting daily legislative operations. Duties include preparing the chamber, delivering correspondence, and assisting senators and staff with official documents.

Only U.S. high school juniors are eligible, and a senator must formally sponsor applicants. Because each senator can nominate only a small number of students, and the national cohort is tiny, this politics program is consistently recognized as one of the most competitive academic-year opportunities in civic leadership.

5. Student Historian Internship – New-York Historical Society

Dates: October 29, 2025 – June 24, 2026
Location: New-York Historical Society, New York City
Benefits: $700 stipend upon successful completion

This internship is ideal for students who love history, museums, and storytelling. The Student Historian program includes weekly after-school sessions where interns learn archival research, public programming, and digital storytelling. The internship is a free, paid program where high school students earn a $700 stipend upon completion.

The 2025–2026 theme centers on “Our Composite Nation: Frederick Douglass’ America,” allowing interns to research issues of identity, citizenship, and social change through original historical sources.

Interns meet weekly after school during the academic year, participate in seminars led by museum historians and educators, and develop a final digital or physical project for public presentation.

6. NASA OSTEM Internships

Dates: Fall 2026
Location: NASA centers nationwide + virtual options
Benefits: Paid internship

​​NASA OSTEM internships allow high school juniors and seniors (age 16+) to support mission-aligned technical projects. Fall interns work part-time during the school year in areas like engineering, coding, robotics, astrophysics, and communications.

Eligibility requires U.S. citizenship and a minimum 3.0 GPA. Because each NASA center selects its own interns and most positions attract large applicant pools, students should treat the program as very competitive. The opportunity to contribute to real scientific and engineering missions makes it one of the most respected STEM-driven fall internships for high school students.

Application deadline for the fall cohort is on May 22, 2026, 11:59 p.m. ET.

7. U.S. Treasury Student Internship

Dates: September – December 2025
Location: Washington, D.C. & hybrid options
Benefits: Unpaid internship

The U.S. Treasury’s student internship invites high school, college, and graduate applicants to join team projects in economic policy, domestic finance, tax analysis, and international economics. Interns help prepare research notes, data models, and policy briefs and may attend internal seminars and meetings.

Since the program primarily serves university students, opportunities for high schoolers are competitive but possible for those with strong quantitative performance and interest in economics or policy. It’s a standout choice for students considering economics, government, or international relations majors.

8. Project TRUE Internship

Dates: Runs September – December annually
Location: Bronx Zoo + NYC park sites
Benefits: Paid internship; students receive a stipend and MetroCard

9. EnergyMag Research Internship

Dates: Quarter-time placements (1–9 months) offered year-round, including fall

Benefits: Unpaid internship

EnergyMag is among the fall internships for high school students that offer online research participation focused on battery storage, energy innovation, and renewable energy markets. Students complete literature reviews, technology analyses, and industry reports under the guidance of an editor or research mentor. The flexible quarter-time format works well for students who want to gain research experience without a rigid weekly schedule.

This virtual research internship is tied to fast-evolving sustainability trends. It lets students gain a stronger understanding of how renewable technologies move from research into real-world adoption.

10. Tech Flex Leaders

Dates: 9-month academic-year program (Fall + Spring)
Location: NYC, Los Angeles, and Miami (hybrid)

Participants receive a stipend, build a portfolio, and gain access to summer internships with partner companies. Plus, the program prioritizes motivated students from underrepresented groups in tech.

The internship program partners with corporate sponsors and local employers. These partnerships allow students to gain exposure to workplace expectations and emerging tech roles they can pursue after graduation.
