High school is a great time to lock in your academic interests and really focus on your strengths. If mathematics is your area of expertise, or even if it is something you wish to hone and better, online math programs for high school students might be just what you’re looking for. 

These programs offer you the unique opportunity to be within the comfort of your home and collaborate with a diverse pool of peers from various backgrounds, cultures, and educational experiences worldwide. 

An online learning format academically covers everything an in-person class provides, and all at lower rates, since there are no housing or travel costs. The social experiences in an online program are also curated to complement the academic experience. Additionally, a virtual program offers you a flexible schedule, allowing you to manage your time on your own terms.

What kind of online math programs are available for high school students?

An online math program, when structured correctly, can act as the foundation for your transition to college and help you prepare for university life. However, not all math programs offer the same level of rigor. That’s why careful research is important, so you can pick the programs that are best for you.

Universities worldwide offer online math programs for high school students that cover advanced mathematics, research internships, or mentorship. During these programs, your math skills will be nurtured under the guidance of undergraduate and graduate mentors.

What runs throughout the programs in the list is the rigor of the curriculum, the prestige of the institution, and the networking and learning opportunities you’ll have. With that, here’s a list of 15 Online Math Programs for High School Students.

Additionally, if you’re also interested in in-person math programs, you can have a look at them here.
