The “C” in CK-12 has an intentionally open meaning, reflecting the open nature of the CK-12 platform itself. It can represent ideas such as content, classroom, customizable, connections, and collaboration; all centered around the mission of providing free, accessible learning resources for anyone, anywhere.
Originally, the “C” stood for “connect,” symbolizing CK-12’s goal of serving as a connecting force in K-12 education.
