The for-profit University of Phoenix, which has seen a significant enrollment decline in recent years, is planning to close more of its brick-and-mortar operations, the Phoenix New Times reports, citing internal communications and sources among school employees. The cutbacks will reportedly close about 20 locations nationwide.

The campuses include both full-sized campuses and smaller learning centers. The full-sized locations include ones in Albuquerque, Detroit, El Paso and Tucson; the smaller centers include ones in San Bernadino, California, and The Woodlands, Texas.

The university did not confirm the exact number of closures, but it did tell the Phoenix New Times it was "instituting a teach-out phase at several of our campus and learning center locations." Current students at those locations will not be affected, but the university is not accepting new students at those places.

This is not the first time the school has trimmed locations. In 2012, it closed 100 campuses and eliminated 800 jobs nationwide.

As recently as 2010, the University of Phoenix had about 500,000 students. In 2016, the enrollment was around 139,000.
