A couple things to add here.

Within the past bunch of years the Georgia Board of Regents has consolidated quite a few institutions.
Georgia State University (D1) and Georgia Perimeter College (NJCAA) = Goergia State University (D1)
Waycross College (NJCAA) and South Goergia College (NJCAA) = South Georgia State College (NJCAA for now)
Macon State College (No Athletics) and Middle Georgia College (NJCAA) = Middle Georgia State College (NAIA)
Gainesville State College (No Athletics) and North Georgia State College and University (D2) = University of North Georgia (D2)
Augusta State University (D2) and Georgia Health Sciences University (No Athletics) = Georgia Regents University (until they were sued) = Augusta University (D2, except for golf)
Abraham Baldwin Agricultural College (NJCAA) and Bainbridge College (no athletics) = ABAC (NJCAA for now. They have multiple 4-year programs)
Georgia Southern (DII) and Armstrong State (DII) = Georgia Southern (D1)
Albany State University (DII) and Darton State (NJCAA) = Albany State (D2)
Kennesaw State (DI) and Southern Poly (NAIA) = Kennesaw State (D1)

Many of the other NJCAA schools in the state are moving to a hybrid system where they also offer 4 year degrees. The Technical College System is expanding their role and replacing the community colleges in many areas. A few of them play sports as part of the NJCAA's Georgia Collegiate Athletic Conference.

So in terms of movement, I would expect that there are a few more schools that would make the jump to NAIA in Georgia within the next few years. There might even be a school or two that drop from D2 to D3. I was talking to a senior admin at one of the public schools in the state who mentioned to me that their school is considering dropping to D3. The school has quite high academic standards and the discussion has started. One sticking point is that the fee to submit the application is above 100k!



On a side note, I am a NJCAA cross country coach. We compete against NJCAA, NAIA, D3, and D2. Schools. By and large the difference between a NAIA school and D2 in cross country depends on the amount of money for scholarships. There are a few really good NAIA schools (SCAD-Atlanta comes to mind) but also some really bad ones. There are some good D2 schools (Augusta, GCSU) and some really bad ones (FVSU, Paine). It depends on the amount of money a school is willing to spend.

One last thing. West Georgia has hinted at moves up to D1 for a while. They and UNA were good competition. With the deal that the A-Sun and the Big South have, they also might make the move. Recently, they hired away the Cross Country coach from Mercer.
