10 Internships for High School Students During School Breaks in 2025
Why Internships Matter
For many high schoolers, the idea of “internship” sounds like something reserved for college students. But more and more companies, nonprofits, and labs are opening their doors to ambitious teens. Internships during school breaks — whether summer, winter, or even spring — allow students to test-drive career paths, build professional networks, and add real-world experience to their resumes.
These opportunities not only develop hard skills like coding, research, or design but also soft skills such as communication, teamwork, and time management. Most importantly, internships give high school students stories and experiences they can bring into college applications, interviews, and future career choices.
