HARRISBURG (AP) – The PA State System of Higher Education could merge six of its 14 universities into two new institutions. It released planning documents Monday, two days before an expected board vote on the plan. A vote to proceed starts a 60-day public comment period. A final vote would be scheduled for this summer, with implementation in 2022. Chancellor Dan Greenstein warns that some system schools are not sustainable without radical change. Under the plan, Bloomsburg, Mansfield, and Lock Haven Universities would merge, as would California, Clarion, and Edinboro. All six campuses would remain open, with integrated faculty and curriculum.
