12 Business Internships for High School Students in Florida

For high school students, internships are a great way to explore a field of interest while gaining practical experience. If you’re interested in business, whether that’s entrepreneurship, marketing, finance, or project management, internships allow you to get a behind-the-scenes look at how businesses operate across different industries. Many programs pair you with experienced mentors, let you contribute to projects, and offer structured workshops to help build workplace and leadership skills.

You don’t need to have a set career path in mind to benefit from a business internship. These opportunities help you build transferable skills, such as communication, collaboration, critical thinking, and time management, that will serve you well in any future academic or professional setting. Some programs are paid, others may offer academic credit or career training benefits, and many are designed to support your college and career readiness.
