Butler County Community College joined the Cal U Educational Alliance on Monday, along with three other Pennsylvania community colleges.

Graduates of BC3, the Community College of Allegheny County, the Community College of Beaver County and Penn Highlands who have earned a two-year associate of arts or associate of science degree will pay 20% less for tuition if they enroll at California University of Pennsylvania, according to a news release from the institution.

Transfer students make up about one-third of each year’s incoming class, said Tracey Sheetz, dean of admissions at Cal U, in a statement.
