15 STEM Internships for High Schoolers

Why wait until college to start doing internships? Now more than ever, organizations are actively searching for high school talent to help them with important research and project development initiatives. Heads up: many of these are even paid opportunities, which means your summer job could be the first step in your future career!


Why Do Internships in High School?


There are so many reasons that starting internships in high school can give you a competitive edge for both college and future careers. Here are just a few of the top reasons to look for an internship:


Gain relevant industry experience. Although other experiences, such as volunteering and traditional part-time jobs, help you develop important soft skills that you can take to any job, internships show you what it takes to succeed in the industry you’re interested in. STEM internships in particular will often allow you to focus on developing your logical and analytical thinking skills, solve problems, and acquire skills such as research, data analysis, or coding.


Connect with professionals in your field. Many of the internships below pair you with a mentor, who not only guide you through some of the tasks you may be unfamiliar with, but they can share their educational and professional journey with you. You can ask them about what to do in your high school years to prepare for success in college and in your anticipated career.


Strengthen your resume or portfolio. Internships count as a form of work experience, and they might catch the eye of future employers or college admissions counselors. Not only that, but the life experiences you have during an internship could provide you with rich material for an engaging admissions essay.


As you can see, there are plenty of reasons to get an internship, and the best news is that many of the internships listed below are paid opportunities, so you can even earn money while you pursue your passion.
