Grantham University (Grantham University) was established in 1951 and is located in Los Angeles. It is a private school and a Grantham radio license school. Its founder, Donald Grantham, is an engineer and a World War II veteran who provides certification courses for the Federal Communications Commission after returning from the battlefield, and other World War II veterans. In the 1950s and 1960s, new campuses were opened in Washington, DC; Hollywood, California; Seattle, Washington; and Kansas City, Missouri. In 1961, the university was officially recognized by the U.S. Department of Education. Grantham School of Electronics (GSE) is accredited by the Distance Education and Training Committee. In 1968, GSE was renamed Grantham School of Engineering (GCE). A second campus was established in Los Angeles in 1974. In the next few years, GCE consolidated all its activities into Los Angeles and offered only distance learning courses. In 1990, GCE was approved to operate in Louisiana and moved to Slidell. It was licensed by the Louisiana Regent in 1993.
In 2005, Hurricane Katrina struck the main campus of Grantham University in Slidell, Louisiana, destroying approximately 80% of its facilities. A few days later, more than 140 employees reopened the university in a temporary office in Kansas City, Missouri. The university decided to permanently relocate to Kansas City and obtained an operating certificate from the Missouri Department of Higher Education. In June 2006, Grantham University signed an articulation agreement with Bellevue University and Wyoming Central College. Grantham University signed a memorandum of understanding with the National Defense Acquisition University (DAU) in January 2007 to accept educational credits obtained through successful completion of DAU courses and programs at Grantham University as transfer or elective credits.
