The Keystone School

What The Keystone School does

The Keystone School is an accredited online private school serving Pre-K-12 students across the United States, operating as a wholly-owned subsidiary of Stride, Inc. (formerly K12 Inc.). Founded in 1974 and headquartered in Bloomsburg, PA, the school delivers self-paced online education through its own platform integrated with K12.com login infrastructure. Current offerings include full-time elementary, middle, and high school programs, homeschool curriculum options, individual course purchases, credit recovery programs, Advanced Placement and Honors courses, and curated grade-level Core Collections (1st-8th grade bundles). The school holds full accreditation and NCAA approval, with diplomas recognized in every U.S. state.

The school serves a diversified customer base across two primary motions: direct-to-consumer (homeschool families, full-time and part-time students, credit recovery students, and adults completing high school diplomas) and B2B channel partnerships (the "Solutions for Schools" program serving over 5,000 middle schools, high schools, and institutions with blended learning courses). Revenue is generated through subscription-based tuition across all programs, with enrollment processed via website, phone, and online information sessions. The school is supported by 29 employees and licensed, state-certified teachers delivering instruction across the platform.

The school's distribution is purely domestic, with explicit enrollment restrictions on residents of numerous countries due to U.S. Treasury requirements. The Keystone School competes in the online K-12 private school market alongside other Stride, Inc. brands and independent accredited online schools, with differentiation centered on long-tenured brand equity, NCAA approval, state accreditation, and the institutional channel breadth.
