you will want to find your near TN Technology center. To my understanding they are the only places to get an LPN in TN (unless there are private school options)
you can just google tn technology centers and you should find a website where you can go to various locations.
LPN training is 12 months. If you later decide to do LPN-RN you can do that. BUT you will still have to have all the general education college classes (A&P 1,2, English, humanities, a few psych classes, possibly micro, etc) At my community college you do not have to take Foundations if you are an LPN (which is a 7 hr class) You do a summer bridge program that is very intense and is 12 credit hours, then you finish out the last 2 semesters with the RN students. So you still have to do like 34 credit hours of nursing classes. As a regular RN student I have to do 42 hrs of nursing classes - so you can see it really doesn't knock much off of your education time..only like 8 credit hours for being an LPN.
Personally this is the route I chose: 1yr of gen ed mostly online while i applied to RN program. One year into RN program (with one year to go) you can intern at many hospitals..make pay comparable to an LPN. So really you don't come out ahead doing an LPN program then bridge to RN in my book.
Once I finish my ADN I can work as RN and do my BSN bridge online.
Hope that helps..it's a little confusing I know.
