Note: When an organization certifies someone, it may not be meaningful at all, because it is about a company certifying itself and its instructors might not know what they are doing; what they do might be wrong and unscientific (think about those Chi masters). (This is how the commercial world works.) Think about how a Wing Chun or Yoga school certifies itself and others. It is just a business/company that thinks it knows what it is doing and teaching. These organizations' teachings are rarely verified through scientific or logical means.
