Ah, to be a medical doctor. To only have to pass the boards once, and then be done with it. MFT license portability isn’t so easy.
Marriage and family therapists — who, at least in theory, practice the same profession no matter where they roam — are subject to a mishmash of licensure laws around the 50 states, with similar-but-different requirements for education, experience, and examinations. Taking your MFT license to a new state can be a challenge, as you may be forced to provide transcripts and even syllabi from classes taken decades ago, register as an intern or associate even if you’ve been fully licensed, and in some states, go through another testing process.
