K12 Inc. (K¹²) is a US-based private education company that offers online curriculum and educational services for students in kindergarten through 12th grade. It is the the largest online learning provider serving K-12 online schools in the US, offering online public high schools in over half of the states in the US.
Both K-8 (kindergarten through eighth grade) and high school programmes are available.
K12 Inc. virtual schools are typically state-funded schools that use K12's programme and curriculum to offer distance education. The schools are considered virtual public schools.
K12 became a publicly traded company in December 2007.
The company "K12" (un-hyphenated) should not be confused with the general US term "K-12" (with a hyphen). The latter is the North American designation for primary and secondary education, i.e. "kindergarten through grade 12".
