A Complete Middle School Program

At Keystone, we help middle school students grades 6-8 get off to a good start. Our program inspires and motivates students to acquire the skills they need to succeed in high school and beyond. We offer curriculum for a complete middle school education or individual courses to supplement a student’s traditional or homeschool education.

Students enrolled in a complete grade level take a total of five courses: four core courses – one in each core subject area – plus one elective per school year. The curriculum includes Language Arts, Mathematics, Science, and Social Studies for each grade level, and an array of elective and advanced courses.

The comprehensive Keystone curriculum offers online middle school courses based on a learner-centered model that draws from current educational research and meets the high standards of the North American Council for Online Learning (NACOL).

Core Curriculum

The Keystone middle school curriculum is online and includes all core subjects, with grade-specific coursework in Math, Science, Social Studies, and Language Arts. We also offer credit recovery options for students who want to get back on track.


Middle school students can choose from a variety of elective courses each year, including art appreciation, health, music, and foreign languages.

Advanced Courses

For 8th grade students who want a more challenging educational experience in preparation for high school, Keystone offers advanced courses: Algebra I, Spanish I, German I, and French I.

"There seemed to be no hope in finishing high school and I was about to give up. This is when my mom found out about Keystone (a branch of K12). I decided that I was going to give this new and exciting program all that I had, even though I would be starting out as a freshman at 16, I knew that I had it in me to give the program a shot. Keystone essentially gave me my life back."
