I know this issue has frequently come up on these forums and while most of us agreed that a LTCF would protect one from prosecution, the answer has never been definite. During some research for a different issue, I came across this PSP Newsletter that specifically states that a LTCF DOES allow one to have a firearm on school property. See:

Just wanted to make sure everyone was aware.
