ECFMG certification, and when a state asks for it
Almost every pathway names ECFMG certification somewhere. What varies is whether it is required at application, at licensure, or not at all.
Which states this affects
The answer depends on where you trained and what you have already done, so the useful version of this page is the one that reads your own circumstances.
That version is not published yet. No state has been read and signed off, so there is nothing yet to check your circumstances against — how the reference is built explains what has to happen first.
