Westech College's Moreno Valley campus and other locations were abruptly closed Monday amid apparent financial troubles.
Students who showed up for classes at the Moreno Valley, Fontana and Victorville campuses encountered locked doors and notices indicating that all programs had been suspended because of financial challenges, the Los Angeles Times reported.
Calls to the for-profit trade school went unanswered, or were routed to voice mailboxes with automated messages saying that they were "full."
Online representatives were still responding to chat requests and providing information about courses, though they were non-committal when asked about speaking to someone in person.
The Westech College website, westech.edu, did not offer any explanations.
The Moreno Valley campus lists career programs in computer science, design drafting, medical office administration, veterinary care and HVAC repair.
Westech began operations in 1988, with the opening of a campus in Pomona, which closed in 2004 with the opening of the Fontana facility. The college was accredited by the Bureau for Private Postsecondary Education and later the Accrediting Commission of Career Schools and Colleges Technology.
