California Southern University (CalSouthern) is an online university founded in 1978, dedicated to providing accessible, affordable, and high-quality higher education to adult learners. It offers degree programs at the associate, bachelor's, master's, and doctoral levels, with a strong emphasis on fields like psychology, business, nursing, criminal justice, and law. In 2020, California Southern University was acquired by Perdoceo Education Corporation and is now part of the American InterContinental University System (AIUS), continuing its mission to serve students globally through its online platform. CalSouthern is regionally accredited by the WASC Senior College and University Commission (WSCUC).
Historically, this location served as the primary administrative office for California Southern University's online programs, student services, and faculty coordination. Operations are now integrated with American InterContinental University (AIU).
As an administrative office for an online university, the focus was on functional space for staff and technology infrastructure to support remote learners, rather than distinctive architectural features. Current infrastructure is managed by AIU.
Prior to full integration with AIU, the culture at CalSouthern likely emphasized innovation in online education, student support, and a collaborative environment among faculty and staff. This ethos continues within the AIU framework, supporting remote work and student-centric approaches.
The Irvine location historically served as the operational hub for CalSouthern, representing its commitment to providing accessible online education before its acquisition and integration into AIU. Its legacy is continued through AIU's national presence.
California Southern University, through its integration with American InterContinental University (AIU), supports a global student body by offering fully online degree programs. These programs are accessible from various countries, leveraging AIU's robust online learning platform and infrastructure designed to cater to distance learners worldwide, providing educational opportunities without geographical constraints. Student support services are also available remotely to assist international students.
