Although it was nearly a year in the making, the largest collapse in U.S. higher education finally occurred Sunday, as embattled for-profit education chain Corinthian Colleges Inc. – the operator of Everest University, Heald College and WyoTech – announced it would close the remainder of its campuses effective Monday. CCI, which has been at the center of a very public downfall since last July, published a notification on its website Sunday declaring it would cease all operations and discontinue instruction at its remaining 28 campuses. By shutting its doors on Monday, the California-based for-profit chain will end the current college careers of some 16,000 students.
