A virtual school or cyberschool escribes an institution that teaches courses entirely or primarily through online methods. Though there are tens of thousands of commercial and non-accredited courses available online, the term "virtual school" is generally reserved for accredited schools that teach a full-time (or nearly full-time) course of instruction designed to lead to a degree. At the primary and secondary level, accreditation means that virtual schools tend to receive public funding; some publicly funded and private universities also provide accredited online degrees.
