The way Pennsylvania funds its "public system" is sorta weird compared to most others.
There's the top tier which are called "state-related" universities: Penn State, Pittsburgh, Temple and Lincoln U (one of PA's two HBCUs). They're nominally independent (and with the exception of Penn State, privately-owned) institutions that are state-funded (as opposed to being both state-owned, controlled and funded, like the top tier university systems in most states); the institutions themselves maintain control over their affairs without much in the way of state interference, but still get state money. It's actually a system that works kinda well on a basic level with a large state that has two significant power centers (Philadelphia and Pittsburgh), although there has been some friction at UPitt in recent years over the relationship.
Then there's the second tier of Pennsylvania's actually public universities, the PASSHE system, consisting of all the old teacher's colleges that are now universities (the PSAC D-IIs like Bloomsburg, Indiana, East Stroudsburg, Clarion, etc.), basically the PA equivalent of Connecticut's *CSU system.
