K12 Inc was founded in 2000. It was incorporated in Delaware. It is a technology-based education company. It offers proprietary curriculum and educational services created for online delivery to students in kindergarten through 12th grade, or K-12. The Company's curriculum consists of the K12 online lessons, offline learning kits and lesson guides. It has developed an extensive catalogue of proprietary courses, consisting of more than 21,000 lessons, designed to teach concepts to students from kindergarten through 12th grade. Each lesson is designed to last approximately 45 to 60 minutes, although students are able to work at their own pace. A single course generally consists of 120 to 180 individual lessons. The Company's online lessons are accessed through an Online School (OLS) platform. Each online lesson provides the roadmap for the entire lesson including direction to specific online and offline materials, online lesson content and a summary of the major objectives for the lesson. Lessons utilize a combination of technologies including flash animations, audio, video and other online interactivity, coordinated textbooks and hands-on materials and individualized feedback to create an engaging, responsive and effective curriculum. Pronunciation guides for key words and references to suggested additional resources, specific to each lesson and each student's assessment, are also included. Its courses utilize a series of offline learning kits in conjunction with the online lessons to help maximize the effectiveness of its learning system. In addition to receiving access to its online lessons through the Internet, each student receives a shipment of offline materials, including award winning textbooks, art supplies, laboratory supplies (e.g. microscopes and scales) and other reference materials which are incorporated throughout its curriculum. The Company's courses are generally paired with a lesson guide. Lesson guides work in coordination with the online lessons and include the following: overview information for learning coaches, lesson objectives, lesson outlines and activities, answer keys to student exercises and suggestions for explaining difficult concepts to students. From kindergarten through 8th grade, its courses are categorized into seven major subject areas: English and Language Arts, Mathematics, Science, History, Art Music, and World Languages. The Company's Online School platform is an intuitive, web-based software platform that provides access to its online lessons as well as its lesson planning and scheduling tools and its progress tracking tool, both of which serve a key role in assisting parents and teachers in managing each student's progress. It distributes its products and services mainly to virtual public schools, school districts, private schools, charter schools, and directly to consumers. It competes with Connections Academy, LLC; Kaplan, Inc.; KC Distance Learning Inc.; Insight Schools, Inc.; Plato Learning, Inc.; White Hat Management, LLC, and National Network of Digital Schools among others. The Company and the virtual public schools that purchase its curriculum and management services are subject to regulation by each of the states in which it operates.
