A more general question from someone who grew up in PA but haven't been a resident for 30 years:
How are those old teacher's colleges in general doing -- Bloom, Shippensburg, Millersville, West Chester, etc.?
Have they had the same funding battles that PSU has had; do they offer a lower tuition than PSU?
It would take some time to fully answer your questions. Let me try to offer some thoughts, without fully answering your questions.
The PA state schools are doing OK, but beyond that you need to look at each of them specifically.
The baby boomlet peaked in PA HS seniors around 5-6 years ago, and is projected to go down through 2028. This has had a serious impact on the state colleges. Many of them have had to greatly increase their spending on efforts to attract students, with a large part of the focus in states outside of PA and contiguous states, and even going after international students.
West Chester U has done very well. It's located in the Philadelphia suburbs, and thus has a very large college-age population that lives within an hour. Their BOT (believe it's actually a Council of Trustees) was even looking into the possibility of breaking away from the Pennsylvania State System of Higher Education (basically, the state schools), though that no longer seems to be the case.
IUP has new dorms that put to shame anything at PSU. Elizabethtown also really improved their dorms. Several others have put effort and money into assorted physical plant initiatives to attract new students.
The state schools, collectively, suffered the same funding issues under former Gov. Corbett as did PSU. In 2011, Corbett proposed to radically cut their funding. In the end, the funding was cut 18%, and was flat for the rest of Corbett's administration. Gov. Wolf has tried to improve the funding, and has to some extent, but funding has not yet returned to earlier levels.
Between the funding cuts, and the dropping graduation numbers of PA seniors, attendance dropped at most state colleges. It's since risen in several of them, due in part to the initiatives I mentioned above.
Many of these colleges are, as you referenced, formerly teacher's colleges. Around 6-10 years ago, these colleges, and others in PA, were pumping out four times as many teachers as were needed in PA schools. Because of the oversupply, many of these graduates could not get jobs in their field. It took a few years for younger high school students and their families to react to this, but the number of PA degrees in teaching has greatly decreased. Last year, I believe the number of graduates with such degrees was about 1/4 of what it was 6-10 years ago. As a result, many school districts are scrambling to fill positions, and most of these graduates are landing jobs, so it's likely that the numbers will start to increase.
As El-Jefe indicated, the state colleges have significantly lower costs, both in-state and out-of-state than does PSU.
PSU costs: resident tuition - $17,514; non-resident tuition - $31,346; room and board (same for resident and non-resident) - $10,926 (these are University Park costs. Commonwealth Campus tuition rates are lower).
Each State College sets their own rates. Two examples:
West Chester costs: resident tuition - $9,462; non-resident tuition - $20,052; room and board (same for resident and non-resident) - $12,780.
Bloomsburg costs: resident tuition - $7,238; non-resident tuition - $18,096; room and board -- so many options (single, double, triple, quad, dorms; apartments) with different prices for each
