I have several friends who have graduated from Southern's nursing program. I've only heard good things from them about it. I'm not sure about the admissions or entrance test, but I just looked on their website and there is some information: www.southern.edu/nursing
I do know the school has a reputation just from hearing that it has such a high pass rate on the NCLEX. My friends were all anxious about taking it after finishing their degree because the School of Nursing had like a 98% pass rate and so you stand out if you don't pass (They all passed easily).
I live in Collegedale, but I know people who commute from Georgia (some even from Alabama). Its about 10 minutes from Highway 75, but there is a shortcut from the Ringgold exit if you're that far south.
Collegedale is very safe little college town. No worries on that front. And the campus has safety officers that routinely patrol (but mostly just help with flat tires/unlocking doors)
Anyway, when I was on their site, I saw this was who you contact for info about their undergrad program:
Linda Marlowe, B.A.
