High School Tuition
Keystone offers you the best of both worlds—the reputation of a leading online education program and an affordable, flexible program. Whether you're seeking a high school diploma or need courses to supplement your existing education solution, our program can meet your goal.
Per-Course Pricing
Tuition for The Keystone School courses is paid per course, whether you buy a single course or buy multiple courses at once to create a full-time curriculum. In either case, you have one full calendar year from the date of purchase to complete each course.
Diploma-seeking, full-time students generally take 5–6 full-credit courses per year, with a goal of earning at least the minimum 21 credits to graduate within four years, as in a traditional high school program. Course options and prices vary; for example, a science course that includes labs will cost a little more, and correspondence (print-based) courses will cost a little less. But a student can generally expect a full year of full-time high school courses to cost between $1800 and $2800, depending on your chosen course options.
Please note that students have the option to enroll in as many courses as they choose and may progress toward a diploma at their own pace.
Multiple-Course Discounts
Keystone offers a discount to students taking a traditional full course load. The discount applies only when all the courses are purchased at the same time and for the same student:
- 5-course discount: 5%
- 6-course discount: 10%
Please note that the discounts are available only if you enroll by phone. These discounts are not given if you enroll online or by faxing or mailing the enrollment form, and cannot be applied retroactively.
To ensure that Keystone is exactly the academic experience you were looking for, we also offer a 30-day money-back guarantee for all new students. Learn about the Keystone Payment Plan, our family and military discounts, our money-back guarantee, and our refund policy.
