Hear from Students
“I had been in public school up until 8th grade. I decided that I was tired of how the other students treated me and ran over me. I searched for hours until I came across Keystone. Keystone has given me opportunities that no other school has. The teachers care and respond very quickly. If you mess up, Keystone allows you to try again and do a better job. They want to see every student in here succeed and have a great life.”

— Beverly C

You have questions.
We have answers.

At The Keystone School, we offer accredited online courses for homeschool students in pre-kindergarten through 12th grade as well as credit recovery courses and our adult diploma program.
Keystone fits students’ lives by allowing them to study on their own time and at their own pace. That extends to enrollment – feel free to enroll whenever you like by phone, on the web, or by mail. There is no specific time when you must enroll. Whether you purchase a single course or buy multiple courses to create a full-time curriculum, students have one full calendar year from the date of purchase to complete each course at their own pace.
Individual courses start at $250 (with Credit Recovery courses as low as $116) and vary based on type and length. Families can expect full time enrollment to cost between $1,800 and $2,900, depending on the grade level and courses selected. All Keystone courses include:
– Quick, Expert Teacher Support
– High-Quality Learning Materials
– Personalized Grading & Feedback
– Flexible, Self-Paced Curriculum
– Comprehensive Records & Transcripts

Keystone offers a discount to students taking a traditional full course load. The discount is applied to your shopping cart at time of purchase when 5 or more courses are purchased at the same time: Buy 5 courses and get a 5% discount, buy 6 courses and get a 10% discount.

Keystone awards up to 5 scholarships for tuition-free, full-time enrollment per school year to new or returning students.

In addition, Keystone is proud to participate in Arizona’s Empowerment Scholarship Account (ESA). Arizona’s ESA fully covers Keystone’s costs, meaning Arizona students can receive a private education 100% cost-free.

To make Keystone more accessible, we provide a variety of discounts to eligible students, including family discounts, and military discounts. We also offer payment plans.
