Ok I started this morning, but got sidetracked on a call. There is no national FF test, there are some states that have adopted the national standards due to a lack of there own program, however the move is on to due this as per a NIMS directive. The big 3, Florida, Illinois and Oklahoma have the highest FF standards in the nation and I can only speak for Illinois, our system is changing. Currently we have essentials 1-4, FF II and FF III all have the same subject matter in 24 areas each just a little more involved. The new system will be simply, basic and advanced, beyond that I have no idea but they have been saying it's coming for 3 years.
If you mean the Pro-Board certification, as far as I know it is still up to each state to accept or decline the certification. All the extra really means is that your class and test met a standard. I know here in CT the state will accept the class but still make you take the test for most pro board certification levels.
