15 Summer Internships for Mathematics Undergraduates
If you’re an undergraduate studying mathematics, an internship can be a valuable way to see how what you’ve learned in class applies outside the classroom. Internships let you test out potential career paths, strengthen problem-solving and analytical skills, and gain experience that can help with graduate school applications or future employment. They also give you the chance to work on projects that go beyond coursework, often in collaboration with mentors or professional teams.
Summer is an especially good time to pursue one of these opportunities, since you can commit fully without the demands of your regular academic schedule. A summer internship gives you space to focus on research, data analysis, or applied mathematics while also building a professional network that can support your next steps. Whether you’re curious about academia, industry, or public-sector work, summer internships can help you clarify your goals and strengthen your preparation.
