If you're talking about being able to call yourself a Certified Raw Nutritionist or something like that, you might want to do some research at your local library. My understanding is that, in many fields, anyone can put together a certification -- just make one up. They are often put together by businesses who train people on their systems, for example. A certification, therefore, can be very meaningful, completely meaningless, or anything in between, depending on who put it together. A license is a different matter. It almost always involves governmental regulation and testing. (This doesn't mean, of course, that it's always a reflection of real skill and useful knowledge, but it does have legal oomph.) The last time I checked, there wasn't even a licensure program for "nutritionist" in most US states, so it'll be a long time, I'm sure, before there is governmental recognition or regulation of anything like a raw food expert. If you're in the USA, the following link may be of help. http://www.looksmart.com/eus1/eus317836/eus317916/eus64407/eus53476/eus282281/eus287113/eus282309/r?l&&hl=6&ss=1&key=licensing Good luck! :) Carol
