For structural engineers in the USA, there is now a movement afoot to create a structural "certification". This is the result of an effort to alter tha way engineers are licensed.
It goes like this: Doctors are certified by a board that reviews their qualifications, education, experience, references, etc. and then "certifies" them. This doesn't license them in a state, it simply creates a monitored and professional statement about the person.
A state, then, can see that certification and know for a fact that they have the proper credentials to get licensed, and they do.
For engineers, and specifically structural engineers, the certification goal is to create a consensus amoung professionals as to how qualified a particular engineer is. The movement to create a national license will never happen. This is because the entire US constitution would have to be amended to allow it. One state cannot tell another state that it MUST recognize its licensed engineers. Won't ever happen.
But by setting up a certification process, then all states can buy in to that system and individually license the engineer based on that certification....sort of like what the NCEES does currently in keeping a file on you. But now the structural certification is focused on one discipline, and instead of just a file of info, they go the next step and make the certifying statement that the person is qualified. NCEES doesn't render an opinion, it just streamlines the info-communication process.
