I liked both philosophies. So, I chose a school that taught both methods. I was also trained in Neuro Linguistic Programming, NLP, and hypno-anesthesiology, the ability to teach a client to induce their own pain management. You do not need a college degree, but I do have a BS in Business Administration. Other criteria for choosing the school I attended was the fact that they were accredited by the California Board of Education and the California Board of Nurses.
Training is based on hours.
My initial 100 hours, level one, certified me as a Master Hypnotist. This training gives you an overview and foundation of hypnosis. I also did a lateral training of 50 hours to be a Certified Hypno-Anesthesiologist. In January of 1990, I took an oral and written test and graduated as a Certified Clinical Hypnotherapist. Today, the training is an additional 50 hours with each level.
