 After a reorganization that year, these campuses were grouped into four autonomous units, simply called the North La Union Main Campus (DMMMSU-NLUC), the Mid La Union Campus (DMMMSU-MLUC), the South La Union Campus (DMMMSU-SLUC), and the Open University System (DMMMSU-OU).Each unit is headed by a chancellor/director, while the whole system is headed by the university president Dr. Jaime I. Manuel Jr.The North La Union campus serves the seat of DMMMSU's central administration and was created in 1993 out of what were then the College of Agriculture and Forestry (CAF), Institute of Veterinary Medicine (IVM), Institute of Computer Studies (ICS), and Institute of Environmental Studies (IES).
