National American University was established in 1941 as a one-year secretarial school by Clarence Jacobson. It was called National College of Business and was located in a downtown Rapid City building. In 1960, Jacobson had the building that now houses administration for the Rapid City campus constructed at 321 Kansas City Street and moved National College to that location.
In 1962, NCB was acquired by Harold D. Buckingham and members of his family. Shortly after the Buckinghams purchased the school, a period of growth began which led to the construction of the classroom buildings, dormitories, a library, gymnasium, and an auditorium.
NCB was granted collegiate accreditation as a junior college by the Accrediting Commission of the Association of Independent Colleges and Schools in 1966. Senior college accreditation was granted in 1970.
The 1970s brought another period of growth, this time with the addition of several branch locations in the Midwest and Rocky Mountain regions. This trend toward reaching out to other communities resumed in the 90s with the addition of more campuses nationwide and continues today (See below for a complete listing of National American university campuses).
In 1985, NCB earned accreditation by the North Central Association of Colleges and Schools (now called the Higher Learning Commission) and in 1997 the university name was changed to National American University.
The university made its first foray into the world of online education in 1996 and currently offers many classes and several degrees completely online through its Distance Learning campus.
In 2012, the main Rapid City location was moved to its current location on Mount Rushmore Rd., south of Rapid City. This location also houses the central administration offices of the university.
In 2018, Robert Gravely, a former NAU official, filed a lawsuit alleging that the school defrauded the United States government out of millions of dollars in a student aid program, unlawfully paid bonuses to university employees for recruiting students and rigged the accreditation for its medical assisting program.  NAUH also mortgaged real property for $8 million in loans.  In 2018, more campus closings were also planned. 
NAU has closed 8 of their 32 campuses and are in the process of closing several more. 
In 1996 National American University began to develop online courses and degree options for students across the United States as well as internationally. Online programs include associate's, bachelor's and master's degrees in accounting, business, information technology, and health care. Students are also provided access to classes and extensive campus resources including learning resource center services, tutoring services, counseling services, and computer support through a student portal.
In 2012, 53 percent of NAU's students were studying online, while an additional 17 percent were taking some classes online.
In 2018, 77 percent of NAU's students were studying online, while an additional 12 percent were taking some classes online.
In August 2008, NAU's graduate studies program was renamed the Harold D. Buckingham Graduate School, in honor of the late owner of the university. Degrees currently offered are the Doctor of Education in Community College Leadership, a Master of Science in Global Supply Chain Management, a Master of Science in Human Resource Management, a Master of Science in Nursing, a Master of Business Administration degree, and a Master of Management degree with a variety of emphasis areas. Graduate degrees are offered primarily online.
NAU is regionally accredited by the Higher Learning Commission. Several NAU programs are separately accredited by multiple national, educational and professional associations. NAU's baccalaureate and master's degree programs in nursing are also accredited by the Commission on Collegiate Nursing Education 
According to the College Scorecard, NAUH students have a median income after graduation ranging from $19,500 to $34,800. The graduation rate varies between 10 percent and 52 percent.
