There has been talk of making you go to truck driving school to obtain a CDL. I'm not sure it's not already the case in TN. A friend of mine lost his job and was wanting to get a CDL to open up more options. They told him at the local drivers testing station that they wouldn't let him take the test unless he had a "diploma" from a accredited truck driving school.
I got my CDL back when I was 18. It has always came in handy even without a truck driving job.
TN is changing alot of the requirements for this year. You will have to have a specific endorsement if you have a F450 and 10,001 # trailer in tow. This is just one of the ones I know of. Good news is they have a school now for your CDL at exit 188 on I-40.
