Top 20 Free Summer Programs for High School Students

Summer programs are a great way for high school students to gain new skills and explore academic interests and potential careers, while preparing for college. While many of these programs come with a high price tag, there are several free and low-cost options that offer high-quality experiences. So whether you're passionate about writing, science, leadership, or the arts, this article highlights ten programs that make meaningful summer opportunities accessible to all students.

Why Join a Summer Program in High School?

Summer programs allow high school students to build academic, creative, and leadership skills outside of the traditional classroom setting. In addition to skill-building, summer programs foster personal growth and confidence while providing valuable networking opportunities with peers, mentors, and professionals. Overall, these experiences strengthen college applications by demonstrating initiative and passion, as well as help students explore potential career paths through hands-on learning and mentorship opportunities.

How to Find the Right Program for You

Before you can find the perfect program for you, you’ll need to engage in some self-reflection: What academic subjects do you enjoy most? Are there any careers you’d like to explore? What are some of your strengths and weaknesses? Take time to explore your interests, as well as any short-term and long-term goals you may have. This will be key in identifying summer programs that most align with your interests and values. 

Next, you’ll want to consider other factors, like location, duration, eligibility requirements, and cost. These parameters will play a large role in which summer programs will be accessible to you and your family. And finally, remember that cost is not necessarily reflective of quality. After all, some of the most prestigious summer programs offer full scholarships. So instead of looking at cost as an indicator of quality, look at faculty, curriculum, and student reviews instead.

Why Choose Free and Affordable Summer Programs?

It’s easy to assume that quality summer programs always come with a hefty price tag, but that’s simply not true. Many free and affordable summer programs are hosted by top universities, nonprofit organizations, and government agencies committed to providing equitable access to enriching educational experiences.

These programs often offer:

• Rigorous academics taught by expert faculty and professionals.

• Hands-on projects and research opportunities that develop skills beyond the classroom.

• Stipends or scholarships to remove financial barriers and cover travel or living expenses.

• Networking with like-minded peers and mentors who can help guide your future.

Choosing a free or low-cost program means you can gain meaningful experience without the financial strain, making it possible to combine multiple programs or pursue other summer goals.

What Makes a Summer Program Accessible?

So, what makes a summer program accessible? Well, accessibility varies from student to student. So what works for one student may not work for another student. Broadly speaking, though, accessibility is determined by cost, location, and assistive technologies. 

Financial barriers are among the most common issues faced by students and their families. This is why it’s important to explore summer programs that are fully-funded, offer scholarships, or other low-cost options, like a commuter rate. You’ll also want to consider whether there are housing and travel costs associated with a particular program. Finally, you may want to look into programs that offer stipends. After all, some students can’t afford not to work during the summer!

Location can also pose accessibility concerns. Beyond the cost of travel, students with accessibility concerns may need to explore whether buildings are ADA compliant, with wheelchair ramps, elevators, ground-level housing, and more. While some programs may be compatible with ADA standards, virtual programs can also be great options!

Other accessibility concerns may include communication standards and whether a program can reasonably accommodate students with hearing, speech, or cognitive impairments, or students whose first language isn’t English. There are lots of assistive technologies that can be helpful in these circumstances and many virtual programs are designed with these technologies in mind.
