If you're a high school student interested in math and looking to build skills beyond the classroom in a flexible format, an online internship is a solid way to start. These internships cover areas like data science, cryptography, finance, healthcare, engineering, and AI.
Doing an internship shows admissions officers that you take charge of your learning and are passionate about the field. Internships can also help you understand how math works in practice, which can strengthen your college application. Being good at math is often linked to strong reasoning and problem-solving skills, which are important in many academic fields.
There are many online math programs, but not all offer the same level of prestige, rigor of professional experience, or opportunities to network. We’ve thus compiled a list of 15 great online math internships for high school students.
