Well, as a massage therapist we have to pass a twenty four hour course every two years to keep out massage license. These classes can be in any modality we choose, deep tissue, myofascial trigger point release, reflexology, ayurveda massage, Thai massage, tuina, amma,californian massage, esalen massage, medical massage, craniosacral. Some courses are live hands-on and really you get the most training this way and learn the most as you can practice the new skills you are learning on real people. But I also found that many LMT's (licensed massage therapists) order videos to watch at home to practice and then they can pass a test online where you are asked a series of questions and need a certain number of correct answers to pass and get your certification in whatever modality you are taking!
The videos usually go with a books which is most of the times about 30 pages long and ends with a test where you can test your learning, then when you are ready, after having practiced the exercises on a live person, a friend of yours, or family member, you can go online to their website and pass the real test, where you are required to have at least 60 percent right answers. If you fail you are able to pass again and pay a repays fee; some of these courses are very expensive 300-400 dollars if you order the videos and the texts. The state of Florida requires 24 hours of CEU's every two years.
