Excerpt from naums.net:

University-Model Schooling began in 1992 with the implementation of the GPA Project ... project organizers developed a new educational model called University-Model Schooling or UMS. This new model, with its university-structured schedule, was first implemented in a UMS test school formally established on December 18, 1992. The test school opened for its first year of operation in the fall of 1993 ... Positive results were experienced almost immediately and exceeded the project organizers' original expectations ... Formally established on April 8, 2005, NAUMS, Inc. now serves as the centerpiece of the University-Model School® Christian movement.
