Frequently Asked Questions
What kinds of online learning programs are available to high school students?
You’ll find a mix of formats, including structured university coursework like the Harvard 7-Week Online Secondary School Program and Cornell’s Pre-College Online Program, research-focused experiences like NASA SEES and NASA GeneLab for High Schools, and skills-based tracks like the Girls Who Code Pathways Program. Horizon’s Research Seminars and Labs offers a different kind of option, letting you conduct independent, mentored research across subjects like data science, machine learning, and political theory rather than following a fixed course curriculum.
Do you need prior experience in a subject to apply?
It depends on the program. Some, like the Girls Who Code Pathways Program, are designed to introduce concepts to students without prior background, while others, like NASA GeneLab for High Schools, require you to have already completed at least one relevant course, such as biology. Research-focused programs like Horizon are generally open to students in good academic standing rather than requiring specific subject prerequisites, though a few of Horizon’s specialized tracks do have prerequisites.
Are there free options available?
Yes, several programs on this list don’t charge a fee. MITES Semester, NASA SEES, the Girls Who Code Pathways Program, Gilder Lehrman’s History U, and NASA GeneLab for High Schools are all free to participate in. Horizon’s cost varies depending on the program type you select, but financial aid is available there as well.
Which programs let you study a specific academic subject in depth?
If you want to go deep on a single subject, Stanford Pre-Collegiate Summer Institutes, Johns Hopkins CTY Online Programs, and the Columbia University Online Summer Program all let you focus intensively on one area, whether that’s computer science, mathematics, or the humanities. Gilder Lehrman’s History U is a strong option specifically for historical topics, offering ongoing courses you can take on a rolling basis throughout the year.
Can you earn academic credit through these programs?
Some of these programs offer credit-bearing options. The Harvard 7-Week Online Secondary School Program and Cornell’s Pre-College Online Program both offer courses that can carry academic credit, with cost varying based on how many credits you take. Others, like MITES Semester and NASA SEES, are non-credit but provide strong academic enrichment and, in some cases, letters of recommendation or research experience that can support college applications.
Is there a way to pursue independent research rather than structured coursework?
Yes. If you want to move from taking courses into producing an original research project, Horizon’s Research Seminars and Labs pairs you with a professor or PhD scholar to develop a 20-page research paper you can submit for academic publication. The program also provides a letter of recommendation and detailed feedback, and covers over 600 research specializations. You can find the application here.
When should you apply?
Application deadlines for these programs are spread throughout the year, so it’s worth planning ahead. Several early deadlines fall between November and February, including MITES Semester (November to February 1), NASA SEES (typically February), and the Harvard 7-Week Online Program (February 11). March brings a cluster of deadlines, including MIT Beaver Works Summer Institute (March 30), NASA GeneLab for High Schools (March 15), and Stanford CNI-X (March 2), while the Girls Who Code Pathways Program has a later deadline of August 26. Horizon, by contrast, has multiple deadlines throughout the year across its Spring, Summer, and Fall cohorts, giving you more flexibility if you miss an earlier cutoff.
