it is a big deal and Louisiana/LSU should make it a priority to rise to that level.
No it's not. REGIONAL accreditation is what really matters. The vast majority of schools aren't nationally accredited, mainly because they don't need to be. Harvard, Yale, Stanford and plenty of other great schools are only regionally accredited. Why would they waste money and time on a misconception around national accreditation. Most schools won't even accept all transfer credits from nationally accredited schools
