The primary difference is in the type of benchmark that the programs are trying to attain. Most of the 4 to 5 years schools have been started by Manual Osteopathic Therapists that have been trained and emigrated from Europe, Australia or Asian countries where the training is 4 to 5 years. In Canada, Massage Therapists go through rigorous training in Anatomy, and Physiology, whereas most other places in the world, and even in the United States, the requirements for Massage Therapy training are much lower. It is with this preconceived idea that many of those school approach the requirement to have a 4 to 5-year program, as such based on a Type 1 WHO model. Those schools who have a condensed model are the ones who require that the individual taking Manual Osteopathic Therapy have prior experience in the health-care industry(ies) and take the approach of the Type 2 WHO model.
