If you are planning to practice in Florida, you will need to complete a state approved program for licensing. The national exam is only a part of the process. Contact the Florida Massage Therapy Board. I doubt the board will allow on-line programs (hands-on or otherwise) to be acceptable for training. I also doubt a massage school will allow someone to just do the hands-on training classes without requiring the rest of the coursework to be completed.
