On March 18, 1993, the Superior Council for Education in plenary session ratified Universidad Diego Portales as successfully fulfilling its institution mission, for which it was designated as having "Full Institutional Autonomy", authorized to bestow all categories of academic degree and title independently.
In 2004 Universidad Diego Portales became one of the first private universities to achieve institutional accreditation as a university from the National Undergraduate Accreditation Commission (CNAP) in three areas: Institutional Management, Undergraduate Teaching, and Equipment and Infrastructure.
