How much is the test? You get to take it as many times till you pass?
I think it was free for anyone from any state, and I think you can take it as many times as necessary. Once you pass it cost $25.oo a year to have your name listed, as being certified. And it is available to anyone, regardless of whether they are in the business, or not.
Once you pass, there are opportunities to get the (12 I think) continuing education credits needed over 5 years, either on line or at seminars to continue your certification, or after 5 years you can take the test again. The training is free, and can be accessed through:

There are people from other states, mostly neighboring listed on the " Certified Applicator" list. The current list is very small, since we need to send in the $25 each beginning of the year & I know I have not received notice that it is open now to pay for another year.
